Answer:
True. Hypoxemia is indeed a deficiency of oxygen in body tissues. It occurs when there is a lower-than-normal level of oxygen in the blood. This can be caused by various conditions such as lung diseases, heart problems, or high altitudes where there is reduced oxygen availability. Hypoxemia can lead to symptoms like shortness of breath, rapid breathing, confusion, cyanosis (bluish discoloration of the skin), and can potentially be life-threatening if severe or left untreated.
HDLs remove the build-up of cholesterol on the walls of arteries.
High-density lipoproteins, or HDLs, are known as "good cholesterol" because they help remove excess cholesterol from the bloodstream and transport it to the liver for excretion. HDLs are essential for preventing atherosclerosis, or the buildup of cholesterol on the walls of the arteries. By acting as scavengers and removing cholesterol build-up from the walls of the arteries, they reduce the risk of plaque formation and narrowing of the arteries.
In contrast, LDL (low-density lipoprotein) is sometimes referred to as "bad cholesterol" because they can increase the risk of atherosclerosis by causing cholesterol to build up in the walls of arteries.
So, the correct option is A.

Every person have different body response on the way they store or burn fat. The ectomorphs are usually called skinny fat for they have low weight but relatively have high body fat. However, they are good in burning fat easily so they end up having little observable body fat.
The other body type is the endomorph that has high tendency to store body fat resulting to have big body because their genetic make-up limits their ability to put on muscle mass.
Lastly, people with mesomorph type can build muscle quickly. They have generally softer and rounder body with responsive muscle cells that tend to store fat easily.
