If a person has a diet high in saturated fats, _________ molecules can carry cholesterol from the liver to cells and to the arte
leonid [27]

Answer:

If a person has a diet high in saturated fats, LDL cholesterol molecules can carry cholesterol from the liver to cells and to the arterial walls whereas HDL cholesterol transports cholesterol from the cells to the liver where it is converted to bile salts which can modulate cardiovascular function.

Explanation:

Cholesterol is a lipid generated in the liver that is used to make hormones and vitamin D, but can also be ingested when eating fats.

Cholesterol can be divided into two types: LDL (low-density lipoprotein) and HDL (high-density lipoprotein).

LDL is commonly known as the "bad cholesterol" and is responsible for the deposit of cholesterol in the walls of arteries, which generates atherosclerosis and can potentially lead to strokes or heart attacks because it occludes the vessels and makes it impossible for the blood to advance.

HDL is also called "good cholesterol" because it takes the cholesterol from the cells to the liver where it'll serve a good cause, instead of blocking the arteries.

To reduce the amount of LDL, it's best to limit the consumption of fatty meats, dairy products and other saturated fats. Foods with a good amount of HDL are those with unsaturated fats, like fish, nuts and seeds.

Which of the following is an example of a density-dependent factor that affects population growth in a terrestrial (land-based)
Ket [755]

Answer:

Example of a Density -dependent factor is Disease.

So option A is correct one.

Explanation:

Disease is more likely to break out and result in deaths when more individuals are living together in the same place. Parasites are also more likely to spread under these conditions

Disease is spread quickly through densely packed populations due to how close organisms are to one another. Populations that rarely come into contact with one another are less likely to share bacteria, viruses and fungi.

Much like the host-parasite relationship, it is beneficial to the disease not to kill off its host population because that makes it more difficult to for the disease to survive.
