Question

Cleavage and Implantation
What is implantation? When does it occur?

Answer 1

well it’s how you make a baby if you can’t don’t want to go into detail

Answer 2

Implantation is what leads an egg to pregnancy. If implantation doesn’t occur then, the fertilized egg comes out with period blood. After fertilization, the egg undergoes series of divisions called cleavage. The cells remain enveloped in the protective egg membrane. This membrane layer hardens after entry of sperm.
