Answer:
C. different alleles of the same gene
Plants absorb water through tiny hairs that cover the surface of the roots. Water is absorbed by osmosis — the movement of water molecules through a semipermeable membrane from an area of high concentration to an area of low concentration. Transpiration, the release of water vapor through the leaves, is the main force that controls the movement of water through a plant. Transpiration is regulated by the stomata, tiny pores on the underside of leaves that open and close to release water vapor and exchange carbon dioxide and oxygen. When the plant’s water concentration is high, the stomata open to release excess water; when the water level drops, the stomata close to conserve moisture.
I think you wanted to know whether the statement in question is true or false. Based on this assumption, i am answering this question and hope that it helps you. It is absolutely true that the slash and burn system of deforestation reduces the number of oxygen producing and puts more carbon in the air.
The correct answer is macrophage.
<span>The macrophage is a type of white blood cells with phagocyte activity which means its main function is to “eat” foreign particles such as bacteria. A macrophage has the ability to locate those particles (viruses, parasites, fungi, bacteria) and do the cleanup.</span>
as you climb higher in the atmosphere, there are three things that happen to your body, one is the circulatory affect, when there is hardly any oxygen in the blood, your body will start to react to this change in supply and either shut down, ((your lungs will give out, and you will pass out because of the lack of O2 in the brain)) or you will become Carbon-drunk. ((your cells will began to literally explode or shrink because of the fact there is no way to filter out your cells of the used up oxygen))
the second thing is with respiratory, your breathing will slow down and it will become hard to breath. its true that oxygen is lighter than carbon-dioxide, but oxygen is heavier then nitrogen and helium. Your body will start to feel heavier than normal and you will become weak. you will start to feel light-headed and eventually pass out if this feeling is new to you.
Third is the carbon affect, your body will end up dying because of it "reusing" carbon cells, and you will end up going into a coma because of the brain damage from no oxygen and too much carbon
