1. Which question is the student most likely trying to answer with this investigation?
2. In 2010, scientists excavated a skull fossil that provides evidence of a newly discovered species of big cat. Based on this discovery and it's location within the fossil record, which statement provides a valid hypothesis to conduct future research?
3. Which procedure should students include in their design?
4. An investigation was designed to determine the effect of ultraviolet light on mold spore growth. Two groups of mold spores were grown under identical conditions, except one group was exposed only to ultraviolet light, while the other group was grown in total darkness. In this investigation, the group of mold spores grown without receiving any ultraviolet light is known as the
5. A biologist formulates a hypothesis, performs experiments to test his hypothesis, makes careful observations, and keeps accurate records of his findings. In order to complete the process of the scientific method, the biologist should:
6. Which of these would be the best conclusion based on the data in the table?
7. A biologist in a laboratory reports a new discovery based on experimental results. If the experimental results are reliable, biologists in other laboratories should be able to
8. Which question is the student most likely trying to answer with this investigation?
9. Which statement about the use of independent variables in experiments is correct?
10. In 1917 the biologist Thomas Hunt Morgan conducted studies in which he kept some caterpillars in the dark and placed some others under red, green, or blue lights. Exposure to red light produced butterflies with brightly colored wings. Exposure to green light resulted in dark-colored wings. Exposure to blue light or no light resulted in pale-colored wings. Based on the results, what was the most likely conclusion of Morgan's experiment?
