Question

intro to diffusion & osmosis
today, we are diving into on one of the fundamental ways that things work in the universe. these principles explain key events in the life of a cell, such as why oxygen is moving from the air you breathe into your lung tissue and your bloodstream to keep you alive. diffusion and osmosis are pervasive in the life sciences. so its important that you get a solid grounding on what they are and why they happen.
both diffusion and osmosis involve the movement of atoms and molecules in a solution, and are most relevant when that movement involves crossing a cell membrane.
consider a single - celled organism that lives in soil or in pond water or in your gut. in most cases, would the concentration of nucleotides, amino acids, and sugars be higher inside its cell membrane or outside?
o inside
o outside
o same (no difference)

Explanation:

Single - celled organisms need to accumulate essential molecules like nucleotides, amino acids, and sugars for their metabolic processes and survival. They often actively transport these molecules into the cell, resulting in a higher concentration inside the cell membrane compared to the outside environment.

Answer:

A. Inside
