Hbio Midterm Review 1. All life uses this molecule for the directions to building you: DNA • 2. DNA is transmitted from parent to offspring through this basic unit of heredity: • gene • 3. True or False: All somatic cells in an organism have the same genetic information • TRUE 4. All prokaryotes are what type of organism? Bacteria 5. The order of organization in an ecosystem from most specific to broadest is: species, population, community, ecosystem, biosphere • • • • • • 6. This is a form of asexual reproduction: Binary fission Cloning Mitosis Parthenogenesis regeneration 7. The scientist who is known for his theories of evolution is: Darwin 8. any change to a cell’s DNA that may cause harm: mutation 9. steps of scientific inquiry • • • • • • • • Observation Problem Research Hypothesis Prediction Experiment Conclude (analysis and inference) Communicate • 10. give an example of a biological catalyst and a non-biological catalyst: • Enzyme vs. heat 11. Label the diagram • • • • A. substrate B. active site C. enzyme D. products • Allosteric change? • 12. an organism that makes its own food • Autotroph or producer 13. All the genes that an organism possesses are called its: genome 14. This type of organism provided Earth with its current oxygen levels: producer, autotroph, cyanobacteria (archaebacteria) 15. Any unique characteristic that provides an organism with a way to survive is called an: adaptation 16. a model of the complex feeding relationships in an ecosystem: food web keystone species food chain 17. Describe the types of population growth patterns: exponential – r strategists logistic - K strategists 18. how much energy is passed “up” the food pyramid? 10% of level below Toxins? 100% - more concentrated • 19. the organism at the base of the food pyramid is called a: producer 20. What ingredients must be present for life to exist? • CHO NPS water carbs proteins lipids nucleic acids • Vitamins – coenzymes minerals - cofactors 21. A measure of diversity in an ecosystem is determined by these 2 measurements: species number and species diversity 22. label 23. This is the formula for: • C6H12O6 H20 + CO2 + Energy • Cellular respiration 24. What is this most likely a diagram of? Mitosis 25. Label the molecules carbohydrate & water 26. What molecule? Lipid 27. What kind of reaction? Dehydration synthesis 28. What do enzymes do to the rate of reactions? Speed them up - catalyst 29. What is this image? karyotype 30. Chemicals that indicate the presence of a molecule or reaction are called? indicators Good Luck! • “Chance favors the prepared mind” ~Aristotle • Prepare your essays!
