Answer:</h2>
The organisms is <u>D. Methanogens
</u>
<h2>
Explanation:</h2>
Prokaryotes are the organism which is made up of a cell that does not contain a membrane enclosed nucleus. They have a structure called as nucleiod which looks like a thread in appearance. The eukaryotes are the organism which has membrane bound nucleus.
Among the given list of organism in the options, Methanogens are microorganisms that produce methane as a metabolic result in hypoxic conditions. They are prokaryotic and have a place with the space of archaea.
Apart from this, amoeba, grass and cockroach have membrane bound nucleus.
Answer: Protons
Explanation: Every atom is defined by its protons every element. So if it has 1 proton its hydrogen no matter what. If it has 2 protons its helium no matter what and so on. So if you know the number of protons you know the element.

Answer: B
Explanation:
The epithelium is the thin tissue forming the outer layer of a body's surface and lining the alimentary canal and other hollow structures. And if it damaged the rate of cell fixture is slowed.
The effect of hydrostatic equilibrium on a solar system body is that It gives the body a spherical shape.
<h3 />
<h3>What is hydrostatic equilibrium?</h3>
Hydrostatic equilibrium describes liquid or fluid at rest.
A body of solar system such as Earth has a spherical shape which is not perfect. This spherical shape of Earth and other bodies of the solar system such as;
- Mars,
- Venus,
- Jupiter,
- Uranus etc are caused by the hydrostatic equilibrium.
Thus, we can conclude that, the effect of hydrostatic equilibrium on a solar system body is that It gives the body a spherical shape.
