Q:

How many chromosomes are in a human gamete?

A) 23	B) 46
C) 92	D) 102

Answer & Explanation Answer: A) 23

Explanation:

23 chromosomes are in a human gamete.

Human somatic cells have 46 chromosomes(23 pairs) but a gamete(germ cell) gets half the amount, i.e. 23 chromosomes, (one from each pair). There will be half the number of chromosomes an organism has in its somatic cells (all other body cells except gametes).

For example in humans, the somatic cells contain 46 chromosomes which are the diploid number (2n) and each sperm and egg has 23 chromosomes where one of them is the sex chromosome.

A) can focus very rapidly as pictures change	B) is quicker than the brain
C) can see 2 images separated only if the interval betwen seeing them is more than one-tenth of a second	D) can shut out some of the light

Answer & Explanation Answer: C) can see 2 images separated only if the interval betwen seeing them is more than one-tenth of a second

Explanation:

The eye can see images separately only if they are exhibited at an interval of more than 1/10 of a second. In the case of a movie, the still pictures come one after the other at less than this minimum interval. So we do not see them separately but only as a continuous moving picture.
