Mix Examples- Strategies for Enhancement in Food Production Questions in English

(A) The correct matches are as follows:
$(a)$ Hilsa is a type of marine fish,so $(a-r)$.
$(b)$ Mrigal is a type of freshwater fish,so $(b-s)$.
$(c)$ Drone is the male bee,so $(c-p)$.
$(d)$ Apis is the genus name for honey bees,so $(d-q)$.
Therefore,the correct sequence is $(a-r), (b-s), (c-p), (d-q)$.

(B) $1$. Statement $S$ is true because dairy products like milk,cheese,and yogurt are rich sources of proteins,fats,vitamins,and minerals,which are essential for human nutrition.
$2$. Reason $R$ is also true because a mule is indeed the result of interspecific hybridization between a male horse ($Equus$ $caballus$) and a female donkey ($Equus$ $asinus$).
$3$. However,the reason $R$ does not explain why dairy products provide nutrition to humans. These are two independent biological facts.
$4$. Therefore,both statements are correct,but $R$ is not the explanation for $S$.

(A) The incorrect pair is $A$. Verghese Kurien is known as the 'Father of the White Revolution' in India,which focused on dairy production,not the 'Green Revolution'. The 'Green Revolution' is associated with $M$.$S$. Swaminathan. Huber is correctly identified as the father of Apiology (study of honey bees). Fa-Hien documented the medicinal properties of honey. Interspecific hybridization is the process of crossing two different species,and the mule is a classic example resulting from the cross between a male donkey and a female horse.

(C) $1$. Animal Husbandry is a broad agricultural practice of breeding and raising livestock,which includes Bee-keeping (Apiculture).
$2$. Plant Breeding involves the manipulation of plant species to create desired genotypes,and Callus culture is a technique used in plant tissue culture for this purpose.
$3$. Animal Breeding is the process of selective mating of animals to improve traits. Pisciculture (Fish farming) is a branch of Animal Husbandry,not specifically a method of Animal Breeding.
$4$. Dairy Industry is concerned with the production and processing of milk and milk products.
Therefore,the mismatched pair is Animal Breeding – Pisciculture.

(D) The correct answer is $D$.
$A$. White Revolution is associated with Dr. Verghese Kurien,known as the 'Father of the White Revolution' in India.
$B$. Apiculture (beekeeping) is scientifically associated with François Huber,who is often called the 'Father of Bee Science'.
$C$. The nutritional value and research related to poultry and eggs are studied at the Indian Veterinary Research Institute $(IVRI)$.
$D$. Animal Breeding is primarily associated with the National Dairy Research Institute $(NDRI)$ or specific animal husbandry departments,whereas the Indian Agricultural Research Institute $(IARI)$ is primarily focused on crop improvement and agricultural research. Therefore,this is the mismatched pair.

(B) The correct answer is $B$.
$IVRI$ stands for Indian Veterinary Research Institute,which is primarily involved in veterinary research and animal health,not in the development of maize hybrid varieties.
Maize hybrid varieties are typically developed by institutions like $IARI$ (Indian Agricultural Research Institute).
Embryo culture is successfully used for the germination of orchid seeds.
Pasteurization is a standard technique used in the dairy industry to eliminate pathogens.
Agar agar is the standard gelling agent used in plant tissue culture for callus induction.

(B) Statement $P$ is correct: Single-cell protein $(SCP)$ refers to the dried cells of microorganisms such as algae,bacteria,or fungi,which are grown in large-scale culture systems (fermentation) to be used as protein-rich food or feed.
Statement $Q$ is correct: In plant tissue culture,callus (an undifferentiated mass of cells) is typically grown and maintained on a solid culture medium,which is solidified using agar-agar gel.

$(B)$ Outcrossing is a breeding method where animals of the same breed are mated but have no common ancestors for $4-6$ generations. Santa Gertrudis is an example of this.
$(B)$ Interspecific hybridization involves mating between two different species. $A$ mule is the result of mating between a male donkey and a female horse.
$(C)$ Callus culture involves the growth of undifferentiated mass of cells (callus) on a solid medium, typically using agar-agar gel.
$(D)$ Suspension culture involves growing cells in a liquid medium, which requires constant agitation using a rotary shaker to ensure aeration and nutrient distribution.
Therefore, the correct match is $(A-iv), (B-ii), (C-i), (D-iii)$.

$(B)$ The correct matches are as follows:
$(1)$ Worker bee is a sterile female bee $(B)$.
$(2)$ Rohu is a freshwater fish $(D)$.
$(3)$ Wax is a lipid-based substance that is soluble in ether $(A)$.
$(4)$ Verghese Kurien is known as the father of the White Revolution $(C)$.
Therefore, the correct sequence is $(1)-(B), (2)-(D), (3)-(A), (4)-(C)$.

(B) The correct matches are as follows:
$(1)$ Outcrossing: This is a breeding method where animals of the same breed are mated, but they have no common ancestors on either side of their pedigree up to $4-6$ generations. Santa Gertrudis is an example of a breed developed through outcrossing.
$(2)$ Interspecific hybridization: This involves mating animals of two different related species. $A$ mule is produced by the mating of a male donkey and a female horse.
$(3)$ Callus culture: This is a technique in plant tissue culture where an unorganized mass of cells (callus) is grown on a solid medium, typically containing agar-agar gel.
$(4)$ Suspension culture: This involves growing cells or small clumps of cells in a liquid medium, which is kept in constant motion using a rotary shaker to ensure aeration and nutrient distribution.
Therefore, the correct matching is $(1)-(S), (2)-(Q), (3)-(P), (4)-(R)$.

(A) The correct matches are as follows:
$1$. Palanpur is the location of Banas Dairy $(1-Q)$.
$2$. Mehsana is the location of Dudhsagar Dairy $(2-R)$.
$3$. Anand is the location of Amul Dairy $(3-S)$.
$4$. Izatnagar is the location of the Indian Veterinary Research Institute $(IVRI)$ $(4-P)$.
Therefore,the correct sequence is $(1)-(Q), (2)-(R), (3)-(S), (4)-(P)$.

(C) In a honeybee colony,there are three castes:
$1$. Worker: These are sterile females that perform all the hive duties,hence $(1)-(P)$.
$2$. Queen: This is the only fertile female in the colony responsible for egg-laying,hence $(2)-(Q)$.
$3$. Drone: These are the fertile males responsible for mating with the queen,hence $(3)-(R)$.
$4$. Hilsa: It is a well-known edible marine fish,hence $(4)-(S)$.
Therefore,the correct matching is $(1)-(P), (2)-(Q), (3)-(R), (4)-(S)$.

(B) Plant breeding is the purposeful manipulation of plant species in order to create desired plant types that are better suited for cultivation,give better yields,and are disease resistant. This process involves the selection and hybridization of plants to introduce genetic variation,which leads to the development of improved varieties.
The objectives of plant breeding (such as increased yield,improved quality,and disease resistance) are fundamentally similar to the objectives of animal breeding,as both aim to improve the traits of organisms for human benefit.
Therefore,both statements $A$ and $R$ are true,but $R$ is not the direct explanation for why genetic variation is obtained through plant breeding; rather,it describes the shared purpose of these disciplines.

(A) Assertion $(A)$ is true because modern techniques like plant breeding and animal husbandry allow for the development of high-yielding,disease-resistant varieties.
Reason $(R)$ is also true because the primary goal of these agricultural advancements is to ensure food security for the rapidly increasing global population.
Since the production of high-quality,disease-free organisms is a direct strategy used to increase food production to meet population demands,$R$ provides the correct explanation for $A$.

(A) The evolutionary progress in the use of plants for food follows a chronological development of human civilization and scientific advancement:
$1$. Initially,humans were hunter-gatherers who collected fruits and edible parts of plants from the wild $(2)$.
$2$. With the discovery of agriculture,humans started cultivating crops systematically $(1)$.
$3$. With the advancement of biotechnology,techniques like tissue culture were developed to propagate plants rapidly $(3)$.
$4$. Finally,modern techniques allow for the production and cultivation of disease-free plants using meristem culture or other advanced methods $(4)$.
Thus,the correct sequence is $2, 1, 3, 4$.

(C) The correct answer is $C$. Amul (Anand Milk Union Limited) is located in Anand,not Ahmedabad. Dudhsagar Dairy is located in Mehsana,and Banas Dairy is located in Palanpur. Dairy farming is the industry involved in the management of animals for milk and its products.

(D) The dairy industry relies on cattle farmers as the primary producers. Their role is central because:
$1$. They maintain high-quality breeds of cattle which ensures better productivity.
$2$. They fulfill their own household nutritional requirements through milk production.
$3$. They contribute to the economy by selling surplus milk to dairy cooperatives or industries.
Therefore,all the given statements are correct.

(D) In a country like India,where a large portion of the population is vegetarian,milk is a primary source of animal protein. However,to ensure proper human nutrition and to address protein deficiency,other sources of animal-based food are also essential. Honey,eggs,and fish are all excellent sources of nutrients. Honey provides energy and medicinal benefits,while eggs and fish are rich sources of high-quality proteins,essential amino acids,and omega-$3$ fatty acids. Therefore,all three are considered important for balanced nutrition.

(D) In a honey bee colony,there are three castes:
$1$. Queen: The only fertile female responsible for egg-laying.
$2$. Workers: Sterile females that perform all colony tasks like foraging,cleaning,and nursing.
$3$. Drones: Fertile males whose primary role is to mate with the queen.
Option $D$ is incorrect because 'Worker' bees are always female,and there is no such caste as a 'non-reproductive male' in a honey bee colony.

(D) The process of plant breeding to develop a new variety with genetic variation involves several steps:
$1$. Collection of variability: Genetic variability is the root of any breeding program.
$2$. Evaluation and selection of parents: Parents having desirable traits are selected.
$3$. Cross-hybridization among the selected parents: This step combines the desired characters into one plant.
$4$. Selection and testing of superior recombinants: This is a crucial step to ensure the progeny has the desired combination of characters.
Therefore,all the mentioned steps are essential for obtaining a variety with genetic variation.

(B) $IARI$ stands for Indian Agricultural Research Institute. It is a premier national institute for agricultural research,education,and extension. It is located in New Delhi,India.

(D) The dairy industry,specifically the cooperative model represented by Amul (Anand Milk Union Limited),has seen massive development in Gujarat. It has revolutionized the rural economy and made India one of the largest milk producers in the world.

(D) Amul Dairy is located in Anand,Gujarat. Dudhsagar Dairy is located in Mehsana,Gujarat. Banas Dairy is located in Palanpur,Gujarat. Izzatnagar is a locality in Bareilly,Uttar Pradesh,and is not a dairy located in Gujarat.

(A) Dudhsagar Dairy,which is a part of the Mehsana District Co-operative Milk Producers' Union Limited,is located in Mehsana,Gujarat. It is one of the largest dairy cooperatives in Asia and plays a significant role in the White Revolution in India.

(C) The statement 'Industrial processing of milk began in the mid-$18^{th}$ century' is incorrect. In reality,the industrial processing of milk and the development of modern dairy techniques,such as pasteurization and sterile packaging,primarily emerged during the late $19^{th}$ century and early $20^{th}$ century,not the mid-$18^{th}$ century. Animal husbandry has indeed been a part of human history since ancient times,and modern technology has significantly improved the distribution of dairy products.

(B) In a country like India,where a large portion of the population is vegetarian,milk is a primary source of animal protein. However,to meet the nutritional requirements of a growing population and to combat malnutrition,the consumption of eggs and fish is highly recommended as they are rich sources of high-quality proteins,essential amino acids,and micronutrients. Among the given options,eggs are widely recognized as a complete and affordable source of protein that complements a milk-based diet to ensure proper human nutrition.

(A) The $ICAR$ (Indian Council of Agricultural Research) is the apex body in India that coordinates,guides,and manages research and education in agriculture,including animal husbandry and poultry science. It has established and promoted the fact that eggs are a source of high-quality protein with high biological value for human nutrition.

(A) The $IVRI$ (Indian Veterinary Research Institute) has conducted extensive research on poultry science. Their studies have demonstrated that eggs possess a high biological value,meaning they contain all essential amino acids in proportions that are highly beneficial for human nutrition. This finding highlights the importance of poultry products in human diet.

(C) In a honey bee colony,there is a division of labor.
$1$. The $Queen$ is the only fertile female responsible for laying eggs.
$2$. The $Worker$ bees are sterile females that perform various tasks like foraging and hive maintenance.
$3$. The $Drone$ is the male bee,which is fertile but does not perform labor; its primary role is to mate with the queen.
Therefore,the correct answer is the $Queen$.

(D) Statement $S$ is false because the majority of the world's fish production (more than $90\%$) comes from marine environments,not freshwater.
Reason $R$ is also false because while Major Carps (like Rohu,Catla,Mrigal) are freshwater fish,Hilsa and Sardines are marine or anadromous fish. Therefore,both statements are incorrect.

(B) Fisheries are an important industry in India because they provide a significant source of income and employment for a large section of the population,especially those living in coastal areas.
While it is true that India has a large number of fishermen,this fact alone does not explain why the industry is important. The importance of the fishery industry stems from its contribution to the national economy,food security,and export earnings.
Therefore,both statements are factually correct,but the reason $R$ does not provide the logical explanation for the importance of the industry $S$.

(B) In a honeybee colony,the caste system consists of the queen,workers,and drones.
$1$. The queen is the only fertile female in the colony,responsible for egg-laying.
$2$. Workers are sterile females that perform all colony tasks like foraging,cleaning,and nursing.
$3$. Drones are the males whose primary function is to mate with the queen.
$4$. Therefore,the statement 'Worker – Males that only perform the function of reproduction' is incorrect because workers are sterile females,and drones are the ones that perform reproduction.
$5$. Additionally,honey is produced from nectar collected by bees,which is processed in their honey stomach (crop) and regurgitated,making the description in option $D$ technically inaccurate as well,but option $B$ is fundamentally incorrect regarding the biological role of workers.

(A) In honey bees,wax is secreted by the abdominal glands (wax glands) of worker bees.
Honey is produced from nectar collected by bees,not by salivary glands.
Major carps (like Rohu,Catla,Mrigal) are freshwater fish,while Mackerel is a marine fish.
Rohu is a freshwater fish,not a marine edible fish.

(A) The White Revolution in India,also known as Operation Flood,was a massive initiative to increase milk production. Dr. $Verghese$ $Kurien$ is widely recognized as the 'Father of the White Revolution' in India for his pivotal role in establishing the $Amul$ cooperative movement and transforming India into the world's largest milk producer.

(B) $(i)$ Correct: Modern techniques like aquaculture and pisciculture are used to enhance production in marine and freshwater habitats.
$(ii)$ Incorrect: Catla,Rohu,and Mrigal are freshwater fish,while Hilsa is a marine/estuarine fish. Major Carps specifically refer to Catla,Rohu,and Mrigal.
$(iii)$ Incorrect: Rohu and Mrigal are freshwater fish,not marine.
$(iv)$ Correct: Fisheries are classified based on the water source as freshwater fisheries or marine (saltwater) fisheries.

(B) In a honey bee colony,there are three types of bees:
$1$. Worker: These are sterile females that perform all the work in the hive,such as collecting nectar and pollen. Thus,$(A-iii)$.
$2$. Queen: She is the only fertile female in the colony responsible for laying eggs. Thus,$(B-ii)$.
$3$. Drone: These are male bees whose primary function is to mate with the queen. Thus,$(C-i)$.
$4$. Major Carp: Mrigal (Cirrhinus mrigala) is a well-known species of major carp used in aquaculture. Thus,$(D-iv)$.
Therefore,the correct matching is $(A-iii), (B-ii), (C-i), (D-iv)$.

(A) $1$. Major carps are freshwater fishes like Catla,Rohu,and Mrigal. Hilsa is a marine fish (anadromous). Therefore,the pair 'Major carp $\to$ Hilsa' is incorrect.
$2$. Pomfret is a well-known marine edible fish.
$3$. In a honey bee colony,worker bees are sterile females.
$4$. Beeswax is secreted by the wax glands located in the abdomen of worker bees.

(C) The $IARI$ stands for the Indian Agricultural Research Institute. It is a premier national institute for agricultural research,education,and extension. It is located in New Delhi,India.

(C) $IARI$ stands for Indian Agricultural Research Institute. It is a premier national institute for agricultural research,education,and extension,located in New Delhi,India.

(C) germplasm bank is a facility designed to preserve genetic material,such as seeds,pollen,or tissues,to maintain biodiversity and support plant breeding programs.
$A$,$B$,and $D$ are directly related to the conservation and utilization of genetic diversity for agricultural and botanical purposes.
Landscape gardening,however,is an aesthetic and architectural practice focused on the design and arrangement of outdoor spaces,which is not the primary function or objective of a germplasm bank.
Therefore,option $C$ is the correct answer.

(C) The correct answer is $C$.
$A$. Germplasm banks are indeed associated with seed banks as they store genetic material.
$B$. Tissue culture is a technique used for the mass production of new plant varieties.
$C$. Grafting is a horticultural technique used for propagation,not for the conservation of species. Conservation involves methods like cryopreservation or seed banks.
$D$. Landscape gardening is often used for public service and beautification of public spaces.

(A) Statement $P$ describes the techniques used in plant breeding and biotechnology to develop new varieties,which is a correct description of modern agricultural practices.
Statement $Q$ describes the function of a botanical garden or a herbarium,which serves as a repository for plant specimens and provides information for their identification and classification.
Both statements are scientifically accurate in the context of biological studies and botanical research.

(D) The terms $A$,$B$,and $C$ represent pairs of techniques or facilities used for the study,propagation,or display of plants in a controlled or managed environment. $A$ (Tissue culture and cloning) involves plant propagation. $B$ (Glasshouse and conservatory) provides controlled environments for plant growth. $C$ (Botanical garden and landscape gardening) involves the cultivation and display of plants. However,$D$ (Conservation and hybridization) pairs a broad ecological goal (conservation) with a specific genetic breeding technique (hybridization),making it the odd one out as it does not represent a pair of similar facilities or cultivation methods.

(D) Floriculture is a branch of horticulture concerned with the cultivation of flowering and ornamental plants for gardens and for floristry,comprising the floral industry. It involves the production of bedding and garden plants,foliage plants,potted flowering plants,cut cultivated greens,and cut flowers.

(A) : The increased vigour displayed by the offspring from a cross between genetically different parents is called heterosis. Hybrids from crosses between different crop varieties ($F_1$ hybrids) are often stronger and produce better yields than the original varieties.

(C) : Ley farming is an agricultural system where the field is alternately seeded for grain and left fallow for growing hay or used for pasture.
During the fallow or pasture period,the soil is filled with the roots of grasses and other plants.
Subsequent ploughing mixes these organic materials into the soil,which improves soil structure and increases the nitrogen content,especially when legume forage crops are used.
This practice also protects the soil from erosion by maintaining constant soil coverage.

(A) The Green Revolution refers to the period of significant increase in agricultural production in India,which occurred during the mid-$1960s$.
This phase involved the development and use of high-yielding varieties $(HYVs)$ of wheat and rice,improved irrigation facilities,increased use of fertilizers,and better pest and disease control.
$Norman E. Borlaug$ is known as the Father of the Green Revolution globally for developing semi-dwarf wheat varieties.
In India,$Dr. M.S. Swaminathan$ is recognized as the Father of the Green Revolution.
In $1963$,wheat varieties like $Sonalika$ and $Kalyan Sona$ were introduced,and in $1966$,semi-dwarf rice varieties like $IR-8$ and $Taichung Native-1$ were introduced,marking the onset of this revolution.

(B) : Newcastle disease is a highly contagious viral disease affecting many domestic and wild avian species.
The causal agent,Newcastle disease virus $(NDV)$,is a negative-sense single-stranded $RNA$ virus.
Transmission occurs by exposure to faecal and other excretions from infected birds,and through contact with contaminated feed,water,equipment,and clothing.
Signs of infection with $NDV$ vary greatly depending on factors such as the strain of virus and the health,age,and species of the host.
Symptoms include respiratory signs (gasping,coughing),nervous signs (depression,inappetence,drooping wings,paralysis),swelling of the eyes and neck,diarrhoea,rough or thin-shelled eggs,and reduced egg production.

(C) The correct matches are as follows:
$A$. Cross breeding: Hisardale $(Q)$ is a new breed of sheep developed by crossing Bikaneri ewes and Marino rams.
$B$. Bee keeping: Apis indica $(S)$ is a common species of honey bee used in apiculture.
$C$. Fisheries: Sardines $(P)$ are a type of fish commonly harvested in fisheries.
$D$. Interspecific hybridization: A mule $(R)$ is produced by the mating of a male donkey and a female horse, which is an example of interspecific hybridization.
Therefore, the correct matching is $A-Q, B-S, C-P, D-R$.

(C) The incorrect statement is $C$. While it is true that India is an agricultural country and employs a large portion of the population ($62$ percent),the contribution of agriculture to India's $GDP$ is not $33$ percent. According to the $NCERT$ textbook,agriculture accounts for approximately $33$ percent of India's $GDP$ is an outdated figure; historically,it was higher,but the statement provided in the context of standard biology textbooks often highlights the $62$ percent employment figure while the $GDP$ contribution is significantly lower in modern data. However,in the context of the specific textbook question,the percentage value provided for $GDP$ is factually incorrect compared to the standard curriculum data.
