BIO 210 LAB Exam 1
1. Define solutes in a solution.
- Solutes are substances (solid, liquid, or gas) that are dissolved in a solvent (in lesser amount).
2. Define solvents in a solution.
- Solvents are substances that dissolve solutes (in greater amount).
3. Define solutions.
- Solutions are mixtures that contain a solvent and solute.
4. Give an example: Salt dissolved in water. Identify the solute and solvent.
- Solute: Salt
- Solvent: Water
,5. When carbon dioxide dissolves in blood plasma, which part is the solute?
- Solute: Carbon dioxide
6. When carbon dioxide dissolves in blood plasma, which part is the solvent?
- Solvent: Blood plasma
7. Define passive methods of transport across membranes.
- Passive methods of transport mean that the movement of substances across the membrane requires
no energy or ATP.
8. List types of passive transport.
- Types of passive transport include diffusion, osmosis, and facilitated diffusion.
9. What factors dictate the type of passive transport used by the cell?
, - The charge and size of the substance dictate the type of passive transport used by the cell.
10. Does active transport require energy or ATP?
- Yes, active transport methods require energy or ATP.
11. Give examples of diffusible substances.
- Examples include gases and salts.
12. During diffusion and osmosis, what substances do water always follow?
- Water always follows salt or the highest solute concentration.
13. If a cell is moving small molecules with their concentration gradient through the phospholipids, what
type of membrane transport is it using?
- Diffusion
, 14. Identify the two major parts of the cell cycle.
- 1. Interphase
- 2. Mitosis
15. What are the subphases of interphase?
- G1, S, G2
16. Where does mitosis occur in the body?
- Mitosis occurs in somatic cells.
17. How many cells result from mitosis?
- 2 cells
