Answer: Option B) directly through the lipid bilayer.

Explanation:

Since membrane are made up of a phospholipid bilayer, with hydrophobic heads and hydrophilic tails, it permits the movement of nonpolar (organic) molecules to diffuse through it into the biological membrane. This is because they are lipophilic (lipid-loving) substances.

Examples of molecules that passed directly through the lipid bilayer are pollutants such as poly-aromatic hydrocarbons, benzopyrene etc.

Answer: option B.

Directly through lipid bilayer.

Explanation:

Molecules with high lipid solubility can pass through lipid bilayer.

Lipid bilayer is a structure of the cell membrane that allow small uncharged molecules, lipid and hydrophobic molecules to pass through the cell membrane across their concentration gradient by a process of diffusion. Examples of molecules with high lipid solubility are oxygen, carbon dioxide, lipids, fat soluble vitamins e.t.c. The molecules are unionized form(lipophilic) and can diffuses readily across the cell.

A C4 plant like corn or sugarcane would not thrive in a cool shady forest because of:________
Alborosie

Answer:

The correct answer is - B. lower environmental availability of CO2

Explanation:

In C4 plants they have developed a mechanism for the CO2 concentrating and leads to the lower environmental availability of CO2 for these plants, C4  to avoid photorespiration.

These plants tend to be found in drier environments with high sunlight levels and not thrive in a cool shady forest due to this mechanism that results in low availability of carbon dioxide.
