Answer 1

Ans 30: b

The olfactory epithelium covers the superior turbinate.

Ans 31; a

Gametes are haploid and so undergo meiosis. Somatic cells are diploid and so undergo mitosis.

Ans 32: a

Chromosomes duplicate at a critical point in mitosis called as S phase.

Ans 33: d

Cytokinesis commences during or after the late stages of mitosis or meiiosis.

Ans 34: a

During metaphase chromosomes are engaged in a state of tug-of-war aligning themselves in the middle of the cell

Ans 35: a

RNA makes proteins.
