Atherosclerosis
Explanation:
Correct order of the sequence of events that leads to atherosclerosis is:
c, d, b, a
Development of atherosclerosis is caused by a high concentration of LDL‐cholesterol in the blood, and lowering the level of LDL‐cholesterol reverses atherosclerosis thus preventing cardiovascular disease
Cholesterol is the key component of arterial plaques which gave rise to the cholesterol hypothesis for the pathogenesis of atherosclerosis
Population studies have shown that elevated levels of both LDL cholesterol and apolipoprotein B (apoB) 100, which is the main structural protein of LDL, are directly associated with risk for atherosclerotic cardiovascular events
Answer:
C. Osmosis
Explanation:
Osmosis is the net movement of solvent molecules, usually water, from a region of lower solute concentration to a region of higher solute concentration through a partially permeable membrane. Osmosis is a very useful for moving materials in and out of the cell.
Solutions are mixtures of solutes and solvents. The main aim of osmosis is for all the mixture part to be uniform and the solvent equally dispersed to all the part of the solution.
Osmosis is controlled to a large extent by concentration gradient.
Diffusion on the otherhand is the movement of molecules of a substance from one position to another.
Facilitated diffusion and active transport are just mechanisms for transport within a cell or a body.
