What do you describe what happens to an egg during the first 14 days of the cycle if no fertilisation occurs? ​

Sagot :

The fertilized egg attaches to the lining of the uterus. The placenta then develops. The placenta transfers nutrition and oxygen to the fetus from mother. if the egg does not become fertilized, the lining of the uterus (endometrium) is shed during menstruation.
