A mixture of liquids with different boiling points like water and ethanol or crude oil which is a mixture of hydrocarbons. It can also be used to separate a solution into its â¦ solvent and solute, for example salt solution (salt water) could be separated into water (solvent) and salt (solute).
Most of our success in understanding the genetic basis of common forms of atherosclerosis has come from studies of âcandidate genes,â genes identified by biochemists and subsequently examined for genetic differences and associations in populations. A good example of a candidate gene is apolipoprotein E (apoE).
Some hardening of the arteries is normal as you age. Exactly how atherosclerosis begins or what causes it isn't known, but some theories have been proposed. Many scientists believe plaque begins when an arteryâs inner lining (called the endothelium) becomes damaged. Three possible causes of damage are: Elevated levels of cholesterol and triglycerides in the blood; High blood pressure; Cigarette smoking; Smoking has a big role in the growth of atherosclerosis in the coronary arteries, aorta and arteries in the legs. It makes fatty deposits more likely to form and to grow bigger and faster. This content was last reviewed April 2017.
