- Which portion of the sperm cell contains an atrosome that digests the covering of the ovum?

In Eutherian mammals the acrosome contains degradative enzymes (including hyaluronidase and acrosin). These enzymes break down the outer membrane of the ovum, called the zona pellucida, allowing the haploid nucleus in the sperm cell to join with the haploid nucleus in the ovum.

Is this used on a test? ?

The most common stereotypes could be that boys don't cryboys don't get emotional boys are never as mature as girlsboys are lazyetc.
