Answer:
B the cell will lose water
Explanation:
Because of the hypertonic solution water will move on the concentration gradient leaving the cell and entering the solution. Thus the cell looses water.
Because it is the control center for many hormones
I think release of chlorofluorocarbons (cfcs) is most closely associated with sunburns. CFCs are green house chemicals that are more potent than the current greenhouse chemicals such as carbon dioxide and methane,and therefore should not be released to the atmosphere. CFCs release free chlorine which is responsible for destabilizing and destroying the ozone layer, which absorbs most of the UV radiations.
D. Plants have adapted to deal with the sun in many different ways, and this is one. The stomata are regulated by guard cells, which are activated by different things depending on the species of plant, and guard cells are supposed to keep the stomata from staying open all the time and losing too much water to evaporation. So, the solution is to have the stomata on the bottom of the leaf to prevent direct sunlight contact (and therefore more evaporation), and guard cells to protect the stomata.
