Answer 2

Answer:

To enter the egg, the sperm has to do two things:

• Break through a group of cells known as the cumulus oophorus that surround the egg. The sperm dissolves these cells using an enzyme (1,7). Break through the outer membrane of the egg. The sperm essentially fuses to and digests this membrane using an enzyme (1,7).
