Question #1
Consider statements about vitamins: 1. Vitamin A is stored in the liver. 2. Vitamin B complex is water-soluble. 3. Excess Vitamin D is easily excreted. Which are correct?
A. 2 and 3 only
B. 1 and 3 only
C. 1, 2 and 3
D. 1 and 2 only

Correct Answer: Option D


Explanation:
Vitamin A is a fat-soluble vitamin stored primarily in the liver, and excess can lead to toxicity. The B-complex vitamins are water-soluble and generally not stored in the body in significant amounts. Fat-soluble vitamins (A, D, E, K) are stored in body fat and liver, making excess Vitamin D difficult to excrete, potentially causing hypervitaminosis D. Thus, statements 1 and 2 are correct.

Question #2
The scientist who proposed the 'germ plasm theory' to disprove Lamarckism was:
A. Alfred Wallace
B. August Weismann
C. Charles Darwin
D. Hugo de Vries

Correct Answer: Option B


Explanation:
August Weismann proposed the germ plasm theory, stating that only changes in germ cells (sperm/egg) are inherited, not somatic changes. He cut off tails of mice for many generations but offspring had normal tails, disproving inheritance of acquired characters.

Question #3
Consider statements about vitamins: 1. Vitamin A deficiency causes night blindness. 2. Vitamin B1 deficiency causes beriberi. 3. Vitamin C is essential for blood clotting. Which are correct?
A. 2 and 3 only
B. 1 and 3 only
C. 1, 2 and 3
D. 1 and 2 only

Correct Answer: Option D


Explanation:
Vitamin A is essential for the formation of rhodopsin in the retina; its deficiency causes night blindness. Vitamin B1 (thiamine) deficiency leads to beriberi, characterized by nerve and heart issues. Vitamin K, not Vitamin C, is essential for the synthesis of blood clotting factors like prothrombin. Vitamin C is essential for collagen synthesis and immunity. Thus, statements 1 and 2 are correct.
