which structure will you find in a prokaryotic cell?
nucleus
mitochondrion
golgi body
cell membrane

Explanation:

For the first question, diffusion of ions through a potassium channel, osmosis, and diffusion of oxygen into a red - blood cell are passive processes that do not require energy. Exocytosis is an active process where cells release substances out of the cell and it requires energy. For the second question, prokaryotic cells lack a nucleus, mitochondria, and Golgi bodies which are membrane - bound organelles. They do have a cell membrane which is a fundamental structure for cell integrity and function.

Answer:

1. C. exocytosis
2. D. cell membrane
