Answer:
a. True
Explanation:
Endothelial cells
These cells are found in all the parts of the circulatory system , these are about a cell thick , and composes a wall known as the edothelium , which lines all the blood vessels , i.e. , the arterioles , veins , capillaries , arteries , venules .
Beneath the endothelial cells , there is a layer of smooth muscle cells .
Answer:
Ximena's mom returned with the lab report of her blood lipid profile. Her HDL cholesterol was low and her LDL cholesterol levels were high. The doctor asked her to look closely at her diet. He asked her to increase unsaturated fats and to decrease saturated fats in her diet
Explanation:
Lipids are the most diverse range of compounds that are nonpolar in nature. The lipids are components of the cell membranes. They are formed of fatty acids, glycerol and a phosphate group. In the fatty acids of the unsaturated fats, there are the presence of double bonds. However, in case of the saturated fats, the double bonds are absent. Such fats are saturated with hydrogens atoms. A type of lipid that play important roles in the body is cholesterol.
There are two types of lipoprotein that carry cholesterol in blood. The HDL or high density lipoprotein is termed as good cholesterol, as it carries the cholesterol back to the liver to eliminate it from the body. LDL or low density lipoprotein is the bad cholesterol, as it carries cholesterol and accumulates it in the arteries to form plaques. A lipid profile is a routine blood test that assess the levels of HDL and LDL in blood. Increase in unsaturated fat causes rise in HDL, that is good for cardiovascular health.

Explanation:
Answer: The required [a] for slotion will be -62.7
Explanation:
The specific rotation of pure quinine= -165
% of pure quinine= 69%
% of its enantiomer=ee=31%
Enantiomer excess =(ee)=excess of a single enantiomer/entire mixture×100
Now,
Excess of a single enantiomer=69% - 31%=38%
Entire mixture=69% + 31%= 100%
(ee)=38/100 × 100
=38%
Net rotation= 0.69-0.31=0.38
Hence, [a] for solution will be = -0.38×165= -62.7
