Answer:
It is impossible for a negative stain to colorize the cells in the smear because the chromogen of the negative stain carries a negative charge and is repelled as a result of the negative charge present on the surface of the cell. In this light, the stain can only colorize the background, thus permitting visibility of the capsule and the cell.

I don't think we can answer this question just like that. The question should be formulated a bit differently:
WHAT is in danger from the effects of overfishing?
Well, in the end of the "effect-spectrum" we are in danger, since we also eat fish. But the most affected species are the ones that form the aquatic ecosystems. Such as fish. Examples:
1 - Many of the fish we eat, feed on sea-weed. If there aren't enough fish to eat the growing population of sea-weed, many fish die of intoxication.
2 - We don't have almost any fish restrictions in a way, because we can eat basically all of them. Therefore, many fish (which are also being eaten) find themselves in a lack of food.
3 - Many times, we concentrate on a specific species, which is a main cause of the extinction of species.

Answer:
The movement of proteins and enzymes within a cell is facilitated by intracellular receptors.
Explanation:
Proteins and enzymes (which also are proteins) move inside the cell through intracellular receptors. These receptors are proteins capable of binding other molecules such as proteins and hormones in order to transport them to different cellular locations. Thus, intracellular receptors are key players in signaling pathways that trigger signaling events to regulate a particular function, for example, activating gene expression by transporting proteins to the nucleus.

What do you mean by I control all metabolic activities of the cell
