Molecules are defined as the smallest particles of a chemical compound or an element, and are made up of atoms. Cells are made up of semi permiable membranes that only allow selected materials to move in or out of the cell, therefore due to the big size of molecules compared to atoms the membrane doesn't allow their passage in the cell. Therefore the cell doesn't allow most molecules to diffuse passively to the cell. Secondly, molecules that can enter the cell requires specific carriers carriers that will enable entry of small molecules in the cell.

Which statements correctly explain why biological productivity in the tropical ocean is so meager when compared to biological pr
Anni [7]
<span>The answer to this question would be: 
- The permanent thermocline presents a barrier that keeps nutrients in deeper water from mixing with surface waters.
- The sunlight penetrates deep into the tropical ocean, warming the surface waters and creating stratification of water masses.

In tropical lands, the area is getting sunlight all around the year. This will cause the plant to be able to do photosynthesis all around the year too. Sunlight can penetrate the ocean, but the intensity will be much lower in deeper part. The ocean also become warmer but it will become cold in the deeper part too. </span>
