question 1 (1 point)
fatty acids are hydrophobic (water fearing) molecules; because they are fat soluble and do not dissolve in watery fluids, they need carrier molecules to travel freely in the blood.

○ true (last option partially visible but structure implies true/false)

Explanation:

Question 1

Fatty acids are hydrophobic (lipophilic) as they are non - polar and fat - soluble. Since blood is an aqueous (watery) fluid, hydrophobic molecules like fatty acids cannot dissolve in it freely. They require carrier molecules (like lipoproteins) to be transported in the blood. So the statement is True.

Polyunsaturated fatty acids (PUFAs), especially omega - 3 fatty acids, have been shown to have beneficial effects on cardiovascular health. They can help reduce the risk of arteriosclerosis by reducing inflammation, improving lipid profiles (e.g., reducing triglycerides, increasing HDL - cholesterol in some cases), and preventing the oxidation of LDL - cholesterol. So PUFAs do provide good dietary protection against arteriosclerosis. The statement is True.

Numerous research studies have demonstrated that the Mediterranean diet, which is rich in fruits, vegetables, whole grains, healthy fats (like olive oil), and lean proteins (like fish), is associated with a reduced risk of cardiovascular events such as stroke and heart attack. This is due to its beneficial effects on blood pressure, cholesterol levels, and inflammation. So the statement is True.

Answer:

True
