BIO 1500
1. Diffusion: Movement of molecules from an area of higher concentration to an area of lower concentration.
2. Sodium Hydroxide: NaOH (Strong Base)
3. Phenolphthalein: Colourless in acid, pink in alkali (turns pink)
4. Solution: A mixture that's the same throughout Solvent + Solute
5. Solvent: Largest component of solution (Usually water)
6. Osmosis: Diffusion of water (solvent) through a selectively permeable membrane
7. Solute: Smaller component of solution
8. Tonicity: The ability of a solution surrounding a cell to cause that cell to gain or lose water.
9. Isotonic: when the concentration of two solutions is the same. Solvent and Solute are same.
10. Hypertonic: Having a higher concentration of solute than another solution (solvent)
1/3
, 11. Hypotonic: Having a lower concentration of solute than another solution (solvent)
12. Accuracy vs. Precision: accuracy: how close experimental value is to accepted value; precision: how
closely measured values agree with each other( repeat and refine)
13. Meniscus: The curved upper surface of a liquid in a tube
14. What do digestive enzymes end in?: "Ase"
15. Enzyme: A type of protein that speeds up a chemical reaction in a living thing
16. active site: the region on the enzyme where the substrate binds
17. Do enzymes lower activation energy?: yes they do
18. Are enzymes reusable?: Yes enzymes are reusable.
19. how to get the mean of a data set?: Add up all the numbers and divide by the amount of numbers
used.
20. What is range?: the difference between the highest and lowest scores in a distribution. Subtract biggest
2/3
