Explanation:

1. The cheek is to the side of the nose. Lateral means to the side, so the answer is E.
2. The right iliac/inguinal region contains the appendix and parts of the large intestine, and the gall - bladder is also in the right side of the abdomen in a related area. So the answer is E.
3. A red blood cell with 2% solutes in distilled water (0% solutes) has a higher solute concentration inside. Due to osmosis, water moves into the cell to equalize the concentration, so the answer is B.
4. In an isotonic solution, the solute concentration is the same inside and outside the cell. So water moves in and out at equal rates, and the answer is D.
5. The transverse plane divides the body into top and bottom halves, so the answer is A.
6. The cell cycle starts with interphase (where the cell grows and replicates DNA). Diagram A appears to be in interphase, so the answer is A.
7. The ankle is further away from the torso compared to the thigh. Distal means farther from the origin of a body part, so the answer is D.
8. The elbow is closer to the torso compared to the wrist. Proximal means closer to the origin of a body part, so the answer is E.

Answer:

1. E. Lateral
2. E. Gall bladder
3. B. water into the red blood cell.
4. D. Water will move into and out of the cell at equal rates.
5. A. Transverse
6. A. Diagram A
7. D. Distal
8. E. Proximal
