List molar concentrations (0.0 M, 0.2 M, etc.) at which water entered the potato strips. Why did water move into the potato stri
kati45 [8]

Answer:

- Water entered the potato strips because the potato cells contained higher concentration of solutes than its external environment.

- The solutions are hypotonic to the solution in the potato cells.

Explanation:

According to osmosis, water will move from a region where it is high in concentration to that region where it is low in concentration. However, a region with high solute concentration contains a low water concentration and vice versa.

Hence, according to this question, water is said to move into potato strips from solutions of molar concentrations like 0.0M, 0.2M etc. Water moved into the potato strips because potato cells contained higher concentration of solutes than its external environment. This means that the external solutions are HYPERTONIC i.e. low in solute concentration to the solution in the potato strips.

Cholesterol transported from the cells to the liver by HDL can then be used to synthesize bile.
Leto [7]

Answer:

True

Explanation:

Cholesterol is a lipid organic molecule which is the modified steroid form. The cholesterol is secreted by the animal cells as it a constituent of the animal cell membrane.

The cholesterol easily dissolves in the blood and is hydrophobic in nature so cholesterol is transported into the blood plasma in the form of lipoprotein complex.

There are four types of lipoproteins formed on the basis of their cholesterol density which are: VLDL, LDL, IDL and HDL.

HDL or high-density lipoprotein transports the cholesterol to the hepatic cells of Liver where the Liver enzymes convert the cholesterol to the bile acid and thus bile juice is excreted with bile.

Thus, True is the correct answer.
