Answer:

The presence of cholesterol in the plasma membranes of some animal cells <u>enables the membranes to stay fluid when cell temperature drops</u>.

Explanation:

Cholesterol is an essential lipid in the basic structure of cell membranes. The membranes must have a fluid structure so that the proteins integrated in them can move ''horizontally'' to interact with their ligands and with other proteins. With excess saturated fat the membranes become rigid, but only with the necessary unsaturated fat the membranes are extremely fluid, and very sensitive to changes in temperature. Cholesterol stabilizes the structure of the membranes; preventing the collapse and crystallization between lipid chains that would lead to loss of fluidity and excessive rigidity in the membrane. By decreasing the temperature; as temperatures drop, fluidity decreases, an effect that partially counteracts the presence of cholesterol.

Explanation:

The above answers are correct.

The convergent plate boundary is known to be an area on Earth where subduction occurs. It is a place where two or more lithospheric plates collide. This convergent plate boundary is characterized by deep ocean trenches,  island arcs, mountain ranges, faults and volcanoes.

Pangaea is known to be a supercontinent that actually incorporated almost all the earth's landmasses and it is said to have existed during the late Paleozoic and early Mesozoic eras. It is revealed that over 150 million years the supercontinent began to break apart.
