The following questions (#1-3) refer to a balanced aquatic ecosystem with gravel, water, snails, aquatic plants, fish, algae and sunlight. This is a sealed aquarium in which all organisms are alive and healthy.
1. Which of the parts of the ecosystem are NOT recycled in the system, but flows through it?
2. Which of the organisms listed demonstrate cellular respiration?
3. Which organisms in this aquarium will demonstrate photosynthesis?
4. How is DNA responsible for the following:
5. Meiosis is to as mitosis is to somatic (body) cells.
6. A cell is placed in a solution of salt water. Osmosis will result in the movement of water in which direction?
7. In which direction will the salt move?
8. If you place the cell on a glass slide and add several drops of distilled (pure) water, what would happen?
9. In which types of body cells will cellular respiration occur most often?
10. In what types of organisms will both respiration and photosynthesis occur?
11. What factors increase the rate of enzymatic action?
12. How many chromosomes are found in a typical human gamete?
13. Colorblindness is a recessive disorder in which a person cannot distinguish between certain colors. Most types of colorblindness are caused by sex-linked genes located on the X chromosome. Your mother is colorblind. Your sister is colorblind. If you are female, what is your condition?
14. What are the results of a cross between two heterozygous tall pea plants?
15. What is the relationship between the genus and species names of an organism?
16. Paramecium is to eukaryotes as is to prokaryotes.
17. What is the definition of a species?
18. Evolutionary relationships can be determined by analyzing DNA similarities or blood proteins. Occurrence of (the same / many different ) blood proteins is an indicator of descent from a common ancestor.
19. Plants depend upon the activities of animals for a continuing supply of what substance?
20. What is the chemical equation for photosynthesis?
21. Describe Lamarcks theory of evolution.
22. What happens to the magnification of a light microscope when switching the objective from low to high power?
23. How can one determine the size of a specimen under the microscope knowing the size of the field of view?
24. How does pH affect enzyme action?
25. What are organic compounds, and what are the subunits that compose each?
26. What are biotic and abiotic factors in an ecosystem?
27. How might environment affect genetic characteristics?
28. In which cell organelle does protein synthesis take place?
29. What would be the result if there was a "mistake" in a codon of mRNA?
30. What determines the arrangement of nitrogenous bases in a codon of mRNA?
31. What are the components (elements) that make up nucleotides and nucleic acids?
32. What is the result of tropical rainforest destruction?
33. What is food chain?
34. Know the following terms: herbivores, carnivores, omnivores, parasites, producers, autotrophs, primary consumers, secondary & tertiary consumers.
35. What happens to an enzyme after it has acted on a substance?
36. What is a substrate?
37. The breaking apart of molecules with the addition of water is called what process?
38. What happens to populations in a community when one population is eliminated?
