5. What is the pH of the strongest base? 14

6. What are made up of many amino acids? Proteins

7. Monosaccharides, sugars, and polysaccharides belong to which organic molecule? Carbohydrates

8. How does an enzyme speed up a reaction? Lowers the activation energy

9. What type of cell contains a nucleus and membrane- bound organelles? A eukaryote

10. What is the movement of molecules from areas of high concentration to areas of low concentration? Diffusion (Passive Transport)

11. What are 3 structures found in plant cells, but not animal cells? Chloroplast, cell wall, central vacuole

12. What is the organelle responsible for breaking down food or waste in the cell? Lysosome

13. What 2 organelles make energy for cells? Mitochondria and chloroplast

14. Organisms with 2 identical alleles are…? Homozygous

15. Physically what you see, genotype or phenotype? Phenotype

16. Most sex-linked traits are found on which chromosome? X chromosome

17. Blood type is an example of what type of inheritance? Multiple alleles

18. What type of inheritance causes a blend in the heterozygous individual? Incomplete dominance

19. What is an organism that makes its own food? Autotroph/producer

20. What type of symbiosis is it when one organism benefits and the other organism is unaffected? Commensalism

21. What organisms use nitrogen gas to do nitrogen fixation? Bacteria

22. What are two ways a population can decrease in size? Emigration, increase death rate, decrease birth rate

23. What is the difference between primary and secondary succession? Primary=no soil, from scratch Secondary=soil present

24. What type of cell division creates identical copies of cells? Mitosis

25. What is one thing that happens during Interphase? Growth, DNA Replication, preparation

26. How is cell division different in plant cells as compared to animal cells? Plant cells have a cell plate.

27. Put the phases of mitosis in order. c=prophase, b=metaphase, d=anaphase, a=telophase

28. What are three differences between mitosis and meiosis? 2 vs. 4 cells, diploid vs. haploid, 1 division vs. 2 divisions, somatic vs. gametes, identical vs. different
