(Please help ASAP) Which statement best explains the difference between water temperature at the poles and water temperature at the equator?

A. Due to Earth's rotation, gyres near the poles flow clockwise.
B. Deep sea vents pump steam into the conveyor belt near the
equator.
C. The sun's rays strike the water at an angle at the poles.
D. The water is denser and saltier near the equator, so it holds more
heat.

The correct answer is: absorption.

Explanation:

Absorption is the process in which a substance is carried from the epithelial cells to the bloodstream in order to reach different organs that need the nutrients that are being absorbed.

In the gastrointestinal tract (more specifically in the intestines), the epithelium (the tissue that forms the inner lining of the hollow organs) absorbs nutrients that come from the food that is being digested. Absorption is one of the many functions of the epithelial tissue and is carried in the GI tract.
