Question

________ Changes occur in it that inhibit entry of sperm
A)Polar body
B)Capacitation
C)Acrosome
D)Zona pellucida
E)Pronuclei

The zona pellucida, a glycoprotein layer surrounding the egg cell, undergoes changes after fertilization that prevent additional sperm from entering, ensuring that only one sperm fertilizes the egg. This process is crucial for preventing polyspermy, which can lead to developmental abnormalities.
