answer is D the answer is D the answer is D
Answer:
A group of parasites called myxozoans have traditionally been considered simple multicellular protists. However, because these organisms possess stinging cells, some scientists consider them to be animals in the phylum that is named for such cells, the <u>cnidarians</u>.
Explanation:
Cnidarians are animals with radial symmetry, that is, their bodies can be divided, by different planes, into equal parts. It includes hydras, jellyfish, anemones and marine corals. Its body is a kind of sac with an opening (the mouth) surrounded by a circle of tentacles. Some have a dominant jellyfish phase, others polyp, or both. They present defensive nematocysts with stinging action.
Avoid carcinogens (like smoking residues..etc), eat healthy and sleep well in order to maintain a strong immune system
Signal binding causes a conformational change in the cytoplasmic portion of receptor protein is the best description of how the information is passed across the plasma membrane.
<h3>What is plasma membrane?</h3>
- All cells' interiors are protected from the outside world by a biological membrane called the cell membrane.
- The plasma membrane, sometimes referred to as the cell membrane, is a membrane that exists in all cells and separates the interior of the cell from the outside world.
- A cell wall is affixed to the plasma membrane on the exterior of bacterial and plant cells.
- A cell's cytoplasm is surrounded by a thin, semi-permeable membrane known as the cell membrane (plasma membrane).
- By letting some chemicals into the cell while blocking others, it serves the purpose of preserving the integrity of the cell's interior.
- The semi-fluid living substance known as protoplasm, also known as plasm, is found inside each cell.
- The plasma membrane is a biological membrane that protects this live material, or plasm.

Question:
When an appropriate signal binds to a G protein-coupled receptor, what is the best description of how the information is passed across the plasma membrane?
a. Binding of the signal molecule triggers the cell to produce G protein.
b. The signal molecule is transported across the plasma membrane by the receptor protein.
c. Signal binding causes a conformational change in the cytoplasmic portion of receptor protein.
