Answer:
Higher the altitude, the thinner the atmosphere gets. The total heat content of a system is directly related to the amount of matter present, so it is cooler at higher elevations.
Here cooler means decrease in temperature.
The definition of Diffusion is: The movement of molecules from a high concentration to a low concentration. Many molecules diffuse across cell membranes.
I know this because I looked it up in my science text book and did some research online.
Hope I helped!

Answer:
A. Only a small percentage of cells in a tissue or cell culture are seen to be in mitosis at any given time.
Explanation:
<em>The evidence that suggests that a cell spends the majority of its time in interphase is the fact that only a small percentage of cells in a tissue or cell culture are seen to be in mitosis at any given time.</em>
If such is not the case, a moderate to a large number of cells in tissue or cell culture should be seen in active mitosis.
<em>Because of the longer nature of interphase when compared to mitosis, more cells are caught in the interphase stage of the cell cycle than the mitotic phase.</em>
The correct option is A.
Inbreeding can destroy the genetic variation that we get when two genetically different people reproduce. This can increase chances of birth defects.
