Introduction to Biology Quiz %CODE1% Introduction to Biology 1. Ultimately, all scientific knowledge comes from: experimentation observation textbooks both experimentation & observation 2. A hypothesis must be: proven correct testable observed experimental 3. A scientist testing the affects of a chemical on apple yeild sprays an orchard with the chemical. A second orchard does not receive the chemical. In the fall, the number of apples harvested from each forest is counted. Which of the following is the independent variable in the experiment? the chemical the number of apples the first orchard the second orchard 4. The orchard sprayed with the chemical yeilds an average of 60 apples per tree, the other orchard yields an average of 40 apples per tree. Based on the data, the scientist would: report his data test the chemical on other plants determine that the chemical increases apple yield determine that the results were inconclusive 5. In order for the apple tree experiment to be valid scientifically, both orchards must: receive the same amount of sunlight receive the same amount of water have the same species of apple tree all of these 6. Theories help scientists to: explain large bodies of data prove hypotheses determine truth from lies propose new ideas about how the world works 7. If a theory is challenged by new evidence, which of the following could occur? the theory could be altered the theory is accepted, not the evidence the evidence is wrong a vote is taken on whether to accept the new evidence 8. All living things must: move have two parents eat food maintain homeostasis 9. The mechanism by which evolution occurs is called: creationism natural selection interdependence metabolism 10. The smallest unit capable of carrying out life functions is: a cell tissue DNA blood Score = Correct answers:

The structure contains which functional group aldehyde ketone amino carboxyl 3. Fatty acids that are unsaturated have: an amino group a double bond an excess of protons a carboxyl group 4. The structure below is a: monosaccharide disaccharide lipid polymer 5. Which of the following can have a quaternary structure? fatty acid protein polysaccharide DNA 6. An organic compound is one that: contains carbon is slightly acidic forms long chains is soluble in water 7. Which of the following elements is the LEAST abundant in living organisms? oxygen nitrogen phosphorous sodium 8. Which of the following is used in PET scans? uranium ions isotopes steroids 9. Carbon can form ___ separate bonds with other elements? 1 2 3 4 10. The cohesion of water is caused by: ionic bonds hydrophobic compounds hydrogen bonds covalent bonds Score = Correct answers:
Cell Respiration Quiz %CODE1% Cellular Respiration Quiz 1. Which of the following occurs in both photosynthesis and respiration? chemiosmosis glycolysis calvin cycle krebs cycle2. Which of the following statements is FALSE? glycolysis can occur with or without oxygen glycolysis occurs in the mitochondria glycolysis is the first step in both aerobic and anaerobic respiration glycolysis produces 2 ATP, 2 NADH, and 2 pyruvate 3. This process uses NADH and FADH2 to produce ATP oxidative phosphorylation fermentation glycolysis krebs cycle 4. This process begins with the production of Acetyl-CoA: chemiosmosis glycolysis fermentation krebs cycle 5. Cramps during exercise are caused by: alcohol fermentation glycolysis inhibition lactic acid fermentation chemiosmosis 6. Oxidative phosphorylation is also known as: chemiosmosis glycolysis fermentation electron transport chain 7. The final electron acceptor during oxidative phosphorylation is: oxygen water carbon dioxide ATP 8. Which of the following processes produces the most ATP? glycolysis oxidative phosphorylation fermentation krebs cycle 9. Which of the following is necessary for oxidative phosporylation to occur? ATP oxygen carbon dioxide lactic acid 10. Which of the following is the products of the Krebs cycle? ATP NADH FADH all of these Score = Correct answers: BACK
