The process of physical and chemical breakdown of food into absorbable form is: MCQ with Answer and Explanation

The process of physical and chemical breakdown of food into absorbable form is:
A. Assimilation
B. Digestion
C. Absorption
D. Egestion
Answer: Option B
Solution (By JKExamLibrary)
Digestion converts complex, insoluble food molecules into simple, soluble forms that can be absorbed. It involves mechanical action (chewing, churning) and enzymatic hydrolysis. Absorption is the uptake of nutrients, assimilation is incorporation into body tissues, egestion is elimination of undigested waste.

The structure of DNA was described as a double helix by:
A. Watson and Crick
B. Schrödinger and Heisenberg
C. Darwin and Wallace
D. Mendel and Morgan

Correct Answer: Option A


Explanation:
The double helix structure of DNA was proposed by James Watson and Francis Crick in 1953, based on X-ray diffraction data produced by Rosalind Franklin and Maurice Wilkins. They proposed that DNA consists of two antiparallel polynucleotide chains coiled around a common axis, with specific base pairing (A-T, G-C) holding the strands together.

Question #3
Consider statements about evolution: 1. The theory of use and disuse was given by Lamarck. 2. The theory of natural selection was given by Darwin. 3. The theory of mutation was given by Hugo de Vries. Which are correct?
A. 1 and 2 only
B. 1 and 3 only
C. 1, 2 and 3
D. 2 and 3 only

Correct Answer: Option C


Explanation:
Jean-Baptiste Lamarck proposed the theory of inheritance of acquired characters, based on the use and disuse of organs. Charles Darwin proposed the theory of evolution by natural selection, emphasizing survival of the fittest. Hugo de Vries, a Dutch botanist, proposed the mutation theory of evolution after working on evening primrose, stating that evolution occurs via sudden, large mutations (saltations). All statements are correct.
