Answer:
Water
Explanation:
In simple words, the volume of a cell refers to <u>the amount of water it contains</u>.
In eukaryotic cells may change their volume according to the effects of either the loss or gain of water. Furthermore, these changes in cell volume are extremely important as they work as a signal for different cell processes such as migration, proliferation, or death.
Therefore, the change of cell volume is principally due to the loss or gain of <u>water</u>.
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.
