Answer
This statement is not reasonable as the diagram would generally show a process related to gas exchange. The exiting of carbon dioxide typically involves diffusion, but it doesn't specifically represent active photosynthesis.
Step 2
B. diagram 2 could show facilitated diffusion of urea out of an active muscle cell.

Answer
This statement is plausible; facilitated diffusion allows molecules like urea to move across membranes, particularly when in an active state, but we cannot confirm without viewing the diagram.

Answer
This statement suggests an active transport mechanism which is valid for potassium ions in many cellular processes, where ion pumps play a crucial role in maintaining concentration gradients.

Answer
This statement is consistent with biological principles since oxygen does diffuse into blood cells from capillaries, especially under gradients present in the body.
