Answers

1. A haploid cell contains only one complete set of chromosomes. Haploid numbers of chromosomes are usually found in the sex cells of an organism.

In the body (somatic) cells on the other hand the number of chromosomes is typically a diploid (a pair of each chromosome).

2. During anaphase, chromatids separate and move to opposite ends of the cell. Correct answer: A

Anaphsase is is the fourth stage of mitosis which ensures that each daughter cell receives an identical set of chromosomes. During this stage each pair of chromosomes is separated into two identical, independent chromosomes.

3. The joining of an egg and a sperm is called fertilization and it produces a zygote.

During fertilization two haploid gametes produce a diploid zygote. A fertilized egg is called a zygote until it divides into 16 cells, forming a ball-shaped structure called a morula.
