  1. EOCT Review Biology 2010 30 Questions Mrs. McClain

  2. 1 What does the line graph below show? • The population increased at a constant rate • The population increased rapidly and then leveled off • The population increased at an exponential rate • Ecosystems are able to support any number of species

  3. 2 Mitosis occurs • Only in gamete cells • In somatic cells (body cells) • Only when an organism makes repairs to cells • As part of active transport

  4. 3 All the populations of organisms that inhabit the same area at the same time make up: • A community • An ecosystem • A biome • A biosphere

  5. 4 The substance labeled “catalyst” also is known by what other name? • Antibody • Lipid • Enzyme • Inorganic compound catalyst catalyst catalyst

  6. 5 Down syndrome is the result of an extra chromosome 21 in a gamete. What caused this to happen? • Nondisjunction • Telomeres • Environment • Chromosome inactivation

  7. 6 If a cell is placed in a highly concentrated glucose solution, water will leave the cell by • Osmosis • Exocytosis • Active Transport • Facilitated diffusion

  8. 7 The equation below represents a biological process. Where is this process completed? • Nucleus • Mitochondria • Cell membrane • Chloroplasts

  9. 8 A mimosa plant has the ability to fold its leaves when they are touched. This response is an example of: • geotropism • phototropism • thigmotropism • hydrotropism

  10. 9 What does the pyramid of biological magnification shown below illustrate? • Higher trophic carnivores eat very little food • Toxic substances increase as tropic levels increase in a food chain • Acid precipitation destroys underwater habitats • The process of eutrophication destroys underwater habitats

  11. 10 Why are the structures shown below considered to be homologous? • They belong to organisms that evolved from separate ancestors • They are the result of geographic isolation • They belong to organisms that probably evolved from a common ancestor • They are the result of sympatric speciation

  12. 11 A single strand of DNA with the base pairing sequence C G A T T G is compatible only with the sequence: • T A G C C T • G C T A A G • G C T A A C • C G A T T G

  13. 12 What happens to the total amount of energy as it flows through a food chain? • It remains the same • It increases • It decreases • It increases and then decreases

  14. 13 The cell theory states that: • Living things are made of cells • Cells come from other living cells of the same kind • Cells are the basic unit of all living things • All of the above

  15. 14 Which organelle is the site of protein synthesis? • Ribosome • Mitochondria • Nucleus • Cell membrane

  16. 15 Which of the following kingdoms does NOT contain any heterotrophs? • Protista • Animalia • Plantae • Fungi

  17. 16 Why are eugelnoids classified with plantlike protists? (picture gives you a clue!) • They form pseudopods • They contain chloroplasts and undergo photosynthesis • They have a nucleus surrounded by a membrane • They have a flagellum

  18. 17 In the nitrogen cycle, nitrogen is continuously recycled. Which type of organism break down nitrogen compounds in dead organisms and recycle them into the soil? • Bacteria • Heterotrophs • Green plants • Herbivores

  19. 18 The scientific name for the African elephant is Loxodonta africana. Which is the species name? • Loxodonta • africana • Homo sapien • African elephant

  20. 19 What is released at each level of pyramid of energy? • Animals • Decomposers • Heat • Plants

  21. 20 Which class of macromolecule store and communicate genetic information? • Carbohydrate • Lipid • Proteins • Nucleic acids

  22. 21 Which processes of organisms are involved in the carbon cycle? • Runoff & precipitation • Combustion & precipitation • Nitrogen-fixing & photosynthesis • Photosynthesis & respiration

  23. 22 Which role do bacteria play in the illustration shown below? • Cause disease • Recycle nutrients • Produce medicines • Produce foods

  24. 23 According to the energy pyramid below, which organisms are the primary consumers? • Eagle • Grass • Snakes • Mice

  25. 24 What do DNA and RNA have in common? • Both are double stranded • Both contain ribose molecules • Both contain phosphate groups • Both contain uracil

  26. 25 You suspect that a chemical that you are testing in the lab is strongly acidic. What might be its pH? • 2 • 7 • 11 • 14

  27. 26 A molecule of DNA is made up of __. • Amino acids & proteins • ATP & enzymes • Paired nucleotides • Receptor enzymes

  28. 27 What are the structures labeled A on the paramecium? • Contractile vacuoles • Oral grooves • Food Vacuoles • Cilia A

  29. 28 How is the illustration below interpreted by many scientists? • Mitochondria & chloroplasts were once prokaryotes • Prokaryotes ate mitochondria only • Prokaryotes cells evolved from eukaryotes • Prokaryotes have a nucleus

  30. 29 Which is a product of photosynthesis? • ATP • Glucose • Water • Carbon dioxide

  31. 30 Identify the process that is taking place in the illustration below. • Binary fission • Meiosis • Endospore formation • chemosynthesis

  32. The End
