Answer:
Photosynthesis also relies on a compound called NADP
which is an electron carrier accepts and transfers high-energy electrons. *
External respiration (correct answer) involves the exchange of oxygen and carbon dioxide within the environment.
The exchange of wastes through the skin is just called excretion by sweating.
There is no exchange of nutrients that occur in the lungs but rather absorption of nutrients is the function of the gastrointestinal tract.
The exchange of oxygen and carbon dioxide within the cell is called cellular respiration and involves carrying oxygen from the blood to the cell then the cell uses it as the final electron acceptor in the electron transport chain. The metabolic wastes of the cell, primarily carbon dioxide, goes now to the bloodstream to be exchanged for oxygen in the lungs.
Answer:
B.) Diffusion
Explanation:
Since this is oxygen, not water, and it is going from an area of high concentration to low, it is moving with its concentration gradient, it would be diffusion. If it were water, not oxygen, then it would be osmosis, and lastly, if it were moving from an area of low to high concentration, that would be active transport. Semipermeability is a characteristic of cell membranes, not a method of movement.
