Answer:
The correct answer is A. The cell membrane is both hydrophilic and hydrophobic due to the presence of phospholipid.
Explanation:
98% of the lipids present in cell membranes are amphipathic, that is, they have a hydrophilic end (which has affinity and interacts with water) and a hydrophobic end (which repels water). The three main types of lipids in eukaryotic membranes are phospholipids, sphingoglucolipids and steroids (especially cholesterol); It is worth mentioning that phosphoglycerides and sphingolipids are found in all cells. The latter, glycolipids and steroids, do not exist or are scarce in the plasma membranes of prokaryotic cells, fungi and some protists. There are also neutral fats, which are non-amphipathic lipids, but only represent 2% of the total membrane lipids.

12 years of school, four years of college and four years of medical school.
The first year of training after medical school is called an internship, or more commonly it is called first year of residency or PGY-1 (Post-Graduate Year-1). The following years are called PGY-2, PGY-3, etc. The training that is done after a residency (in a subspecialty) is usually called a fellowship. Much of what you will learn in your chosen specialty will be learned in your residency.
The damage of the alveoli will support the diagnosis of emphysema rather than chronic bronchitis.
Emphysema causes damage to the alveoli of the lungs. This reduces the surface area of the lungs. As a result less oxygen is supplied to the body. The damage can't be undone hence emphysema is a chronic illness. The first symptom is shortness of breath that can reach up to the level where it can happen to the person even at rest.
Chronic bronchitis is the inflammation of the bronchi. These people are more prone to lung infections. The symptom of the disease is wet cough due to production of excessive mucus.
