Answer:
Diffusion
Explanation:
The movement of molecules and ions from a region of higher concentration gradient to the region of lower concentration gradient of the molecules. Its direction of movements depends totally on the direction of the concentration gradients.
Fick's Law is the principal law that underscores diffusion. And it sates that the rate of diffusion is directly proportional to the concentration gradients or differences; the surface area available for the molecules to pass through ;<u> but inversely proportional to the thickness of the separating membrane (diffusion distance. </u>
<u />

Thus the larger the surface area exposed the more molecules pass through into the membrane , the higher the concentration differences the greater the number of molecules willing to break free and escape; but the thicker the separating membranes, the slower the number of molecules getting chances to pass through and the lower the rate of diffusion.
Define objectives and standards, measure performance, compare progress, take required action.
I don't see any options, but it would most likely be the one that is most caring and understanding.
1. True- because scientific theory means that <span>idea supported through research that attempts to explain existing observations or predict new ones.</span>2. False- because a cross-sectional means that its a study that is about different groups.
3. B-<span>An extraneous variable clarifies the relationship between the independent and dependent variables.</span>
Answer:
The cardiovascular system pumps blood from the heart to the lungs to get oxygen. The heart then sends oxygenated blood through arteries to the rest of the body. The veins carry oxygen-poor blood back to the heart to start the circulation process over.
