Question

Answer the following questions.

1)What happens when an ovum does not fuse with a sperm?


2) Why do fishes and frogs lay hundreds of eggs while the hen lays only one egg at a time?​

Answer 1

Answer: 1) If no sperm is around to fertilize the egg, it moves through the uterus and disintegrates. Your hormone levels go back to normal. Your body sheds the thick lining of the uterus, and your period starts.

2)Compared to hens, fish and frogs lay hundreds of eggs because: - In Fish and Frogs, external fertilization occurs. - In the external medium (water), the male releases a large number of gametes while the female parent lays a large number of eggs.
