Answer: C. The Number of Molecules
Explanation: I just took the test, it's correct.
Texas racked the first spot in the ranking of states that is characterized as the state with the most amount of waste generated, carbon dioxide emissions, generally environmentally toxic wastes being emitted to the atmosphere. This is caused by numerous human activities as well as the chemical plants present in the state.
The molecule that could diffuse across the plasma membrane is methane (CH4).
<h3>What is diffusion?</h3>
Diffusion is the movement of fluids or substances from regions of high concentration toward regions of lower concentration.
The plasma membrane is the semipermeable membrane that surrounds the cytoplasm of a cell. The semipermeability means that it allows some molecules through but blocks other substances.
The semipermeable plasma membrane readily allows the passage of small hydrophobic and polar molecules.
Therefore, the molecule that could diffuse across the plasma membrane is methane (CH4).
