NEET 2024 Biology Question Paper with Answer and Solution

$(C)$ The correct matching is as follows:
$A$. Exophthalmic goiter $(III)$: Caused by hyper-secretion of thyroid hormone,leading to protruding eye balls.
$B$. Acromegaly $(IV)$: Caused by excessive secretion of growth hormone in adults.
$C$. Cushing's syndrome $(I)$: Caused by excess secretion of cortisol,resulting in moon face and hyperglycemia.
$D$. Cretinism $(II)$: Caused by hypo-secretion of thyroid hormone during development,leading to stunted growth.
Therefore,the correct sequence is $A-III, B-IV, C-I, D-II$,which corresponds to option $(C)$.

(B) The correct matching is as follows:
$A$. Unicellular glandular epithelium: These consist of isolated glandular cells, such as the $III$. Goblet cells of the alimentary canal.
$B$. Compound epithelium: This is made of more than one layer of cells and has a limited role in secretion and absorption. It provides protection against chemical and mechanical stresses, such as the $IV$. Moist surface of the buccal cavity.
$C$. Multicellular glandular epithelium: These consist of a cluster of cells, such as the $I$. Salivary glands.
$D$. Endocrine glandular epithelium: These are ductless glands that secrete hormones directly into the fluid bathing the gland, such as the $II$. Pancreas (which has both exocrine and endocrine functions).
Therefore, the correct sequence is $A-III, B-IV, C-I, D-II$, which corresponds to option $B$.
