Match the following columns:
Column-$I$ Column-$II$
$a$. Palynology $p$. Silkworm
$b$. Oncology $q$. Pollen grains
$c$. Phycology $r$. Cancer
$d$. Sericulture $s$. Algae
A
$a-s, b-r, c-q, d-p$

$a-r, b-q, c-s, d-p$

Solution

(B) The correct matches are as follows:
$1$. Palynology $(a)$ is the study of pollen grains $(q)$.
$2$. Oncology $(b)$ is the medical study and treatment of tumors/cancer $(r)$.
$3$. Phycology $(c)$ is the scientific study of algae $(s)$.
$4$. Sericulture $(d)$ is the production of silk and the rearing of silkworms $(p)$.

MediumMCQ
In earlier times,the lack of proper care at the time of birth resulting in severe physical pain can be referred to as:
A
Serendipity
B
Teleology
C
Controlled experiment
D
Hypothesis

Solution

(B) The term $Teleology$ refers to the explanation of phenomena by the purpose they serve rather than by postulated causes. In the context of historical medical or biological discussions,it often relates to the philosophical study of design or purpose in nature. However,in the context of this specific question regarding the lack of care at birth leading to physical pain,it is often discussed in historical texts as a consequence of natural or teleological processes where the outcome (pain/suffering) is viewed as an inherent part of the biological or developmental process.
154
MediumMCQ
Which of the following sequences is correct for the scientific method?
A
Question,Define,Hypothesis,Observation,Experiment
B

Solution

(C) The scientific method is a systematic process used to investigate phenomena and acquire new knowledge.
$1$. Observation: Noticing a phenomenon or event.
$2$. Question: Formulating a question based on the observation.
$3$. Define: Clearly defining the scope or variables of the problem.
$4$. Hypothesis: Proposing a testable explanation or prediction.
$5$. Experiment: Conducting tests to verify the hypothesis.
Therefore,the correct sequence is: Observation $\rightarrow$ Question $\rightarrow$ Define $\rightarrow$ Hypothesis $\rightarrow$ Experiment.

Biology is primarily divided into which two branches?
A
Botany and Zoology
B
Zoology and Chemistry
C
Zoology and Physics
D
Chemistry and Botany

160
EasyMCQ
Which of the following is a branch of biology?
A
Botany
B
Zoology
C
Chemistry
D
Both $(A)$ and $(B)$

Solution

(D) Biology is the study of living organisms. It is broadly divided into two main branches:
$1$. Botany: The study of plants.
$2$. Zoology: The study of animals.
Chemistry is a branch of physical science,not biology.
Therefore,both Botany and Zoology are branches of biology.
161
EasyMCQ
What is science?
A
Effective information of every component
B
Systematized knowledge of everything
C
Information about every phenomenon
D
$(A), (B)$ and $(C)$ all three

Solution

(D) Science is derived from the Latin word $Scientia$,which means 'to know'. It is defined as a systematic and organized body of knowledge obtained through observation,experimentation,and logical reasoning. Therefore,it encompasses the effective information of components,the systematized knowledge of objects,and the study of various phenomena. Thus,all the given options are correct.

163
MediumMCQ
What is the first thing a student should consider before conducting a field study?
A
Prior study of the field
B
Season
C
Time of study
D
Climate of the field study area

Solution

(A) Before conducting a field study,the most important initial step is to have a clear understanding of the 'prior study' or background information regarding the specific field or area. This helps in formulating objectives,identifying the scope of the study,and preparing the necessary tools and methodology. While season,time,and climate are important factors,they are secondary to the initial planning and background research of the field.

Biology
B
Physics
C
Chemistry
D
Biochemistry

Solution

(C) Chemistry is the branch of science that deals with the study of matter,its properties,composition,and the changes it undergoes. Atoms are the fundamental building blocks of matter,and their structure,behavior,and interactions are primarily studied in Chemistry.
165
MediumMCQ
Which of the following is an incorrect pair?
A
Tissue - Histology
