Which statement regarding cholesterol is false? it is the precursor for steroid hormones. it is not usually a component of eukaryotic membranes. it is the precursor for bile acids. it has a hydrophilic functional group.

It is not usually a component of eukaryotic membranes.

Explanation:

Cholesterol is responsible for modulating the fluidity of the cell membranes of eukaryotes.

It is produced in most animal cells, and its formation is substantially active in liver cells, where bile acids are synthesized from cholesterol.

In addition, cholesterol is the precursor of steroid hormones such as progesterone, testosterone, estradiol and cortisol.

Cholesterol (like other lipids) is amphipathic, meaning it has a polar head (hydrophilic) and an apolar tail (hydrophobic).

Given the above, it can be concluded that the false statement is "it is not usually a component of eukaryotic membranes".

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
