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:

Quiz Viruses %CODE1% Name: Viruses True/False Indicate whether the sentence or statement is true or false. TF 1. Although viruses do not consist of cells, biologists consider them to be living because they are capable of reproduction. TF 2. Some viruses have a membranous envelope surrounding the protein coat that helps them gain entry into host cells. TF 3. Viruses consist of RNA or DNA surrounded by a coat of protein. TF 4. Prions are the smallest known particles that are able to replicate. TF 5. A virus can only reproduce by controlling a cell. TF 6. Once a virus enters either a lytic or a lysogenic cycle, it cannot change to the opposite type of cycle. TF 7. Prophages and proviruses can both enter lytic cycles and destroy host cells. TF 8. People can contract the influenza virus more than once because the virus tends to mutate rapidly, avoiding the actions of the immune system. TF 9. Smallpox is caused by bacteria. TF 10. Chickenpox and shingles are caused by the same virus. Multiple Choice Identify the letter of the choice that best completes the statement or answers the question. ABCD 11.

A prophage differs from a provirus in that a. a prophage contains DNA, while a provirus contains RNA. b. a prophage is formed during a lysogenic cycle, while a provirus is formed during a lytic cycle. c. a prophage contains DNA found in the infecting virus particle, while a provirus contains DNA produced from viral RNA. d. a prophage becomes integrated into a host cell’s DNA, while a provirus cannot become integrated into a host cell’s DNA. ABCD 19. Which of the following is not a virus linked to cancer? a. Ebola c. hepatitis B b. human papillomavirus d. Epstein-Barr ABCD 20. Which of the following human activities is most closely associated with emerging viruses? a. absence of a vaccination program c. clearcutting of forests b. crowded living conditions d. eating uncooked meat
