Explanation / Answer

1. Cell is hypertonic and bathing solution is hypotonic. 2. This cell would undergo lysis, water moves from low concentration ( bathing solution ) to high concentration (animal cell ) this would leads to lysis of the cell. 3. Oxygen molecules would cross plasma membrane most rapidly. 4. Water would cross more rapidly through plasma membrane because it uses " Aquaporins " . It also called water channels. 5. If a channel protein used to move solutes from higher concentration to lower concentration. This would be "facilitated diffusion". 1. Carbon dioxide is used during the following "Calvin cycle" in photosynthesis.
