Answer:

C. an archaea cell

Explanation:

Both bacteria and archaea have a cell wall, but the bacteria cell wall has peptidoglycan. The archaeal doesn't have peptidoglycan, but some unique proteins. They both also don't have nuclei. A virus doesn't have a cell wall, and a host cell, if eukaryote, would have a nucleus.

4. The picture shows a full moon.
Anuta_ua [19.1K]

Answer:

A full moon occurs when the Moon appears as a complete circle in the sky.

Explanation:

- We see it as a full orb because the whole of the side of the Moon facing the Earth is lit up by the Sun's rays.

- The moon shows no visible light of its own, so we only see the parts of the moon that are lit up by other objects.
