On a bar graph, the x axis represents the independent variable and the y axis the dependent variable.
Answer:
According to Fick's law, the rate of diffusion of any substance across any barrier is<u> directly proportional to the surface area of the membrane or any layer exposed. and the concentration of the diffusing substance available, but the rate is inversely proportional to the diffusion distance available.</u>

Thus the rate at which oxygen will move across the phospholipid bilayer will depend on the concentration or amount per mole of the oxygen molecule hitting the phopholipid at a prticular time and how permeable the phospholipd layer is to oxygen molecules, but the rate of its movement across will be reduced as the distance between the phosphoslipid bilayer and the diffusing molecules increases.
Therefore, the concentration of oxygen should be maximised, the surface area of the phospholipid bilayer should also be maximized. the distances between the phopholipid and the vessel containing the diffusing oxygen molecules should be drastically reduced. With this Fick's law has been applied , and therefore maximum oxygen molecules can diffuse across.

Answer:
The skeletal system is vital in supporting the immune system because : Bones contain marrow, a porous material which creates both white and red blood cells. This replenishment of cells allows the body to fight and expel harmful bacteria, environmental toxins, foreign material e.t.c.
The white blood cells formed by the marrow are instrumental in isolating and destroying harmful particles (either on the site or in lymph nodes), or transporting them to the kidneys or bowels for excretion.
NOTE : Some people have marrow disorders which prevent their marrow from forming new cells; this is caused most often by cancer. Today, it is possible to transplant marrow from a healthy individual to a sick patient, and so help their bone marrow form new white and red blood cells to fight their sickness.
I hope it helps :)
That organ is called the rectum, or more coomonly, the anus. The rectum is the final part of the large intestine and the digestive system, where food that has had all its nutrients extracted (as much as possible, anyway) is sent to be compacted and sent out through the anus in the form of excreta. The contents in the rectum is mostly indigestible fiber and other materials. The rectum at its end connects to the bodily orifice known as the anus.
