1a) B

1b) C

1c) A

2)Hypertonic dehydration occurs when there's an imbalance of water and salt in your body which is happening in A. Hypotonic dehydration occurs when sodium loss is greater than water loss,which is happening in C

Explanation:

When RBCs are placed in a hypertonic (very salty) salt solution, water moves from inside the cell to the outside by osmosis. This causes the cells to shrink. When RBCs are placed in distilled water, a hypotonic solution, water moves from outside of the cell to the inside, causing the cell to swell and rupture.

If red blood cells are placed in pure water, water enters them by osmosis and the red blood cell swell up and burst. If cells are placed in a concentrated solution, water leaves them by osmosis and they are unable to function.

Hope it helps!

Happy easter!!
