Answer:

Explanation: How do things move across a cell membrane?

Summary. Controlling the movement of things in and out of the cell is an important role of the plasma membrane. ... Osmosis is the diffusion of water molecules across a membrane. Water moves in or out of a cell by osmosis until its concentration is the same on both sides of the plasma membrane.

Materials move within the cell's cytosol by diffusion, and certain materials move through the plasma membrane by diffusion (Figure 3). Diffusion expends no energy. On the contrary, concentration gradients are a form of potential energy, dissipated as the gradient is eliminated

Natalka [10]

Answer:

22. C

23. C

24. Not clear, maybe 18%

25. Left ventricle, because according to the graph nearly 50% of the organ contains mitochondria, more than the left atrium.

Explanation:

22. Active transport requires cell's energy to move molecules, usually in the form of ATP.

23. This is a trick question, you might think it is diffusion or osmosis, but is is exocytosis. Diffusion and osmosis don't require vesicles for transport. It isn't endocytosis, because that is moving molecules inside the cell. The question asks for moving out the cell.

24. Look at the chart, it is less than 20, but more than 10 and more than halfway. I am not sure exactly the percentage, I would approximate it to be 18%.

25. Most likely left ventricle.

please give thanks :)
