2. Smithers thinks that a special juice will increase the productivity of workers. He creates two groups of 50 workers each and assigns each group the same task (in this case, they're supposed to staple a set of papers). Group A is given the special juice to drink while they work. Group B is not given the special juice. After an hour, Smithers counts how many stacks of papers each group has made. Group A made 1,587 stacks, Group B made 2,113 stacks. What are the variables of this experiment?

Independent: Control:

Dependent: Constants:

3. Read the following experiment, and graph the results.

Larry was told that a certain muscle cream was the newest best thing on the market and claims to double a person’s muscle power when used as part of a muscle-building workout. Interested in this product, he buys the special muscle cream and recruits Patrick and SpongeBob to help him with an experiment. Larry develops a special marshmallow weight-lifting program for Patrick and SpongeBob. He meets them once every day for a period of two weeks and keeps track of their results. Before each session, Patrick’s arms and back are lathered in the muscle cream, while SpongeBob’s arms and back are lathered in regular lotion. Larry also lifts weights, but does not put any cream on.

5. Define the following terms

a. apex e. energy pyramid

b. abiotic f. producer

c. biotic g. herbivore

d. trophic levels h. carnivore

6. What are some differences between and ecosystem and a population?

7. Using the following organisms (grass, rabbit, hawk) draw an energy pyramid. Label each trophic level and describe the amounts of energy (100 kcal, 10 kcal, 1 kcal) in each level.

8. Some people have a widows peak (hair line that meets in a point at the forehead), where others have no widows peak. A husband and wife both have a widows peak, but two of their children do not. Describe and show evidence to support your description of the type of inheritance pattern described above. (Is it controlled by a dominant or recessive allele?) Show your work and explain your answer.

9. Scenario: A teenage girl has her appendix removed during an operation. 24 hours later the girl begins to run a fever, which quickly rises. She has contracted an internal infection (caused by the bacteria Staphylococcus) during the surgery. Will she survive the infection?

 Outcome #1: 1925: The girl becomes delirious from fever; in a few days, she dies.  Outcome #2: 1945: The girl receives an injection of the antibiotic penicillin, within 24 hours her fever is reduced; she is released from the hospital and on her way to recovery.  Outcome #3: 1965: The girl receives an injection of the antibiotic penicillin, within 24 hours the girl dies.

For each outcome, write 1 paragraph that explains why that outcome is possible at that time in history. Use the terms evolution, natural selection, variation, mutation, and adaptation, fitness, gene, DNA.

10. Explain how bacteria and viruses are different. Be sure to include the affect of antibiotics in your explanation.
