Many protists vary from one another, the answer to this question varies as well. Protists that are similar to animals do not have cell walls at all. Plant- and fungi-like protists have cell walls that are similar to plants. Other protists have a unique cell wall that is different from cell walls seen in other eukaryotic kingdoms.

erma4kov [3.2K]
The number of green bodied insect would probably increase in the grass habitat. The insects that are green would be harder to spot by predators and therefore more likely to survive and produce offspring. The process of natural selection would favor the green color of the body and the future generations will have an increase in numbers of green bodied individuals over the tan bodied individuals.

Rashid [163]

Answer:

a) into the ER

b) into the ER

c) into mitochondria

Explanation:

a) This signal is located at the N-terminus of the protein and acts before the internal signal is synthesized for import into the nucleus. When the protein enters the ER, the sequence of the import signal in the nucleus cannot work because the protein would be prevented from interacting with the cytosolic receptors.

b) The signal that is imported into the peroxisome cannot function once the protein was sequestered in the ER.

c) In order for the protein to be retained in the ER, the protein must first be imported into the ER. Without there being no signal for that import of the protein into the ER, that retention signal could not work.
