What are examples of molecules (related to breathing that move by simple diffusion right through the membrane) 1. goes from higher concentration outside the cell into the cell; whereas 2. moves from higher concentration inside the cell to outside to be exhaled by our lungs.

1. oxygen

2. carbon dioxide

Explanation:

oxygen diffuses from the environment(high) to the cells(low) whereas carbon dioxide diffuses from the cells(high) to the environment(low).

c.more precipitation,but only when emission levels.

answer: accepted answer: aquatic animals use the oxygen dissolved in water to carry out respiration. since the amount of dissolved oxygen in water is low as compared to the amount of oxygen in the air, therefore the rate of breathing in aquatic animals is much faster than it is in terrestrial animals.
