Why do phospholipids form of bilayer in water ? a. the phosphate portions repel each other b. the hydrophilic and hydrophobic parts attract each other c. the phosphate portions attract water, and the lipid portions repel water d. the lipid portions attract water, and the phosphate portions repel water

The right answer is C.

A lipid bilayer, or lipid bilayer, is a thin polar membrane consisting of two layers of lipid molecules.

The outer region on each side of the lipid bilayer is constituted by the hydrophilic heads of the lipids (phosphate group). This region is fully hydrated. The inner region is the hydrophobic core (long fatty acid chains), the water molecules cannot access.

The answer is C. The phosphate portions attract water, and the lipid portions repel water.

This is because the phosphate portions are negatively charged, hence making it polar and hydrophilic. On the other hand, the lipid portions are uncharged and nonpolar, hence making it hydrophobic.

succession returns a disturbed

ecosystem to a more stable state. this is also classified into two (2) types:

primary succession and secondary succession. the primary succession arises when

a new land is transformed and a bare rock has been exposed providing an environment

that can be occupied for the first time. while, secondary succession occurs

when a previously occupied environment was disturbed that kills much of all its

community

explanation:

layer 3 is younger than layer 6.
