Answer:

Hey Queen Messy here!

The predator prey relationship consists of the interactions between two species and their consequent effects on each other. In the predator prey relationship, one species is feeding on the other species. The prey species is the animal being fed on, and the predator is the animal being fed. The predator prey relationship develops over time as many generations of each species interact. In doing so, they affect the success and survival of each other’s species. The process of evolution selects for adaptations which increase the fitness of each population. Scientists studying population dynamics, or changes in populations over time, have noticed that predator prey relationships greatly affect the populations of each species, and that because of the predator prey relationship, these population fluctuations are linked.

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.
