Answer:
Hypercholesterolemia is intimately linked to atherosclerosis, a degenerative disorder that affects the arteries in which atheroma plaques form.
Explanation:
The main consequence of excess blood cholesterol is the development of coronary heart (CH) disease. Numerous studies have shown that CH are more frequent in populations whose diet is rich in saturated fats and cholesterol, and have elevated serum cholesterol levels, while in populations with low LDL cholesterol levels, such as Japan and China, it is lower the rate of coronary heart disease.
Atheroma plaques are deposits of various lipids, especially cholesterol, proteins and calcium salts, which totally or partially obstruct the vessels of the arteries and cause a lack of irrigation.
If the lack of irrigation is located in the coronary arteries that supply the heart, angina pectoris or myocardial infarction can occur. If it occurs in the cerebral arteries, cerebral hemorrhages and thrombosis are frequent. When the obstruction is located in the extremities it can favor the gangrene of a member and, in the worst case, its amputation. Likewise, atherosclerosis causes aneurysms or excessive dilations of the aorta that can cause its rupture.
Excess blood cholesterol can be deposited in various places in the body, such as the cornea, where yellowish plaques form on the skin and eyelids. Other factors that facilitate the onset of atheromas are tobacco use, diabetes, abdominal obesity and male membership.
The expected weight for this child at the age of 4 months would be 13lb (5900g)
<h3><u>
Explanation:</u></h3>
There are some predictions that exists in the growth of the baby. The weight of boy babies tend to be more than baby girls. There will a loss of weight of five to ten percent initially in the first week of born babies. They will again gain their wight in the next coming two to three weeks.
The weight of the infants usually tend to be double of the weight that was during their birth in the month of 4 to 5. It will be triple when they turn one year. In the given example, the infant's weight is 6lb that is 2,912 g. It will be double for the baby following the normal growth at the 4th month. Hence, the weight would be around 13lb (5900g) at the 4th month.
Answer: Option A
Explanation:
The T-cells and B-cells of the immune system are the part of specific immune response.
If the number of T-cells dies then the ability to activate B lymphocytes will also be lost as they help B-cells to secrete antibodies and macrophages to destroy the antigens.
T cells also helps in the activation of cytotoxic T-cells to kill the targeted cell which is affected by antigens.
hence, the correct answer is option A
