Answer 1

24. If a cell has 10% NaCl (salt; or solutes) and 90% water inside of it and the environment it is placed in has the same NaCl to water ratio, the direction that osmosis will occur is no net movement; option C is correct.

25. If a cell has 30% NaCl and 70% water inside of it and the environment outside the cell is 10 % NaCl (salt; or solutes) and 90% water, the direction that diffusion will occur is into the cell; option A is correct.

26. If a cell has 30% NaCl and 70% water inside of it and the environment outside the cell is 10 % NaCl (salt; or solutes) and 90% water, the direction in which WATER will move is into the cell; option A.

27. Endocytosis is NOT a form of passive transport; option D is correct.

28. The structure MOST responsible for maintaining homeostasis is the cell membrane; option D is correct.

29. In the egg lab, the type of solution we were putting the egg in when we had it sit in distilled water is hypotonic; option C.

30. In the egg lab, the type of solution we were putting the egg in when we had it sit in syrup is isotonic: option A.

31. If you are floating aimlessly on a small boat in the middle of the Pacific Ocean with sharks swarming and you are dying of thirst, it would not be a lifesaving decision to drink the seawater around you to quench your thirst because the seawater is hypertonic.

What are hypertonic, hypotonic, and isotonic solutions?

A hypertonic solution is a solution whose concentration is greater than the concentration of the solution in the cell.

A hypotonic solution is a solution whose concentration is less than the concentration of the solution in the cell.

An isotonic solution is a solution whose concentration is the same as the concentration of the solution in the cell.
