In which of the following ways does a fertilized egg differ from an unfertilized egg? a) a fertilized egg has more unpaired chromosomes than an unfertilized egg. b) a fertilized egg has chromosomes that will soon go through meiosis while an unfertilized egg's chromosomes have already divided. c) a fertilized egg has fewer chromosome mutations than an unfertilized egg. d) a fertilized egg has chromosomes from two parents while an unfertilized egg only has chromosomes from the mother.

D

Explanation:

The fertilized egg has 46 chromosomes since it is fertilized by the sperm which makes 23 + 23= 46 so, it is fertilized by both parents. HINT: The sperm is produced in the uterus by the father. An unfertilized egg has 23 chromosomes since it is not fertilized by it's father. Therefore, it is only fertilized by it's mother since the mother produces the egg through the ovaries.

i think the miocene epoch spans the time from 23 million to 12 million years ago.
