Answer:
The slow rate at which diffusion occurs over large distances.
Explanation:
Circulatory system may be defined as one of the most important system of the body that contains arteries and veins. Two main types of circulatory system are open circulatory system and closed circulatory system.
The blood flow all over the body to each cell with the help of the circulatory system. Arteries carry oxygenated blood and veins carry deoxygenated blood in the body. The circulatory system increases the rate of blood flow as diffusion do not allow the transport at long distances.
Thus, the correct answer is option (c).
The solution of wet mount should be hypertonic solution.
<h3><u>Explanation:</u></h3>
Wet mount is a preparation where the specimen is made to place in a glass slide and a drop of solution is put on the slide. The wet mount is primarily used to see vaginal swab, bacterial slides etc.
Here the wet mount uses a hypertonic solution which is primarily 30 to 40% salt solution in distilled water. The function of this solution is to draw water from the cells and to keep them dehydrated.
The dehydration of the cells maintain their shape, and help to keep any stain if provided. So wet mount uses a hypertonic solution.
The form of natural selection is called adaptive radiation
