Answer:

d.

Explanation:

Pubic lice, also known as crabs, are small parasites that feed on human blood. They're usually found on the pubic hair, but can also be found on other parts of the body where a person has coarse hair (such as armpits, eyelashes, and facial hair). Anyone can get crabs and they are very common.

Answer:

When a male and female crab mate, many female decapod crabs can store the male sperm until her eggs are ready to be released. When the eggs are released, the stored sperm flows over them and they become fertilised.

The female crab holds the fertilised eggs in a big spongy mass between its abdominal flap and the body. The eggs are cemented to the pleopods, which are small legs, creating the "berried" appearance.

To keep the eggs healthy, the female crab continually "waves" water over the eggs with the pleopods.
