The rate of photosynthesis would be equal at all light levels.
The rate of photosynthesis would increase with no limit.
The rate of photosynthesis would decrease with no limit.
The rate of photosynthesis would increase but eventually level off.
The rate of photosynthesis would decrease but eventually level off.

- 13. Multiple ChoiceYou read that cats will meow more if they eat more ice cream. You decide to do an experiment to test this hypothesis. Using your cat for the experiment, you feed your cat 50 cm3 of vanilla ice cream, 100 cm3, and no (0 cm3). You made sure that during your experiment, you used the same beaker, same brand of ice cream, the same temperature ice cream, and the same procedure for feeding your cat. Once your cat was finished eating you counted the number of times he meowed in 10 minutes. You recorded your data in a data table.
What is the dependent variable (DV) in this experiment?The catThe amount of ice creamThe number of meowsThe type of ice cream - 14. Multiple Choice

- 15. Multiple Choice
Suppose that species 1 and species 2 have similar appearances but very divergent gene sequences, and that species 2 and species 3 have very different appearances but similar gene sequences. Which statement best reflects their relationship?
Species 1,2,and 3 are all closely related because they either share similar appearance or similar gene sequence.
Species 1 and 2 are most closely related because their similar appearance indicated convergent evolution
Species 2 and 3 are most closely related because of their genetic similarity.
Species 1 and 2 are most closely related because they share a common ancestor with species 3
