The cell membrane is a lipid bilayer made of amphipathic phospholipids, which is fluid and selectively permeable to ions and organic molecules, given that the inside of the cell membrane is hydrophobic and the outside is hydrophilic.
The physical characteristics of the cell membrane, along with the proteins and other biomolecules embedded in it, control what enters and leaves the cell.
What the cell membrane DOESN'T do, is control the nucleus of the cell.

Answer:
1. D. Only DNA contains genetic information
2. D. Nitrogen and Phosphorus
Explanation:
1. Lipids are insoluble in water unlike other molecules. It stores energy within the fat tissues and cushion internal organs against trauma.
Carbohydrates are sugar units such as monosaccharides, disaccharides molecules which makes up starch that is fuel to your cells.
DNA is a type of nucleic acid that contains genetic information which influences your personal characteristics.
2. The family Rhopalodiaceae has the ability to perform nitrogen fixation, which allows diatoms to fix atmospheric nitrogen. And phosphorus has been found in some diatom species in the Black sea region which does not affect its reproduction rate and also helps in carbon cycle.
