Question 12 0.4 out of 1 points A scientist studying aquaculture is interested in how water temperature will influence the growth rates of a particular species of fish. He sets up many tanks with varying water temperatures and measures fish growth over time. Match the correct type of variable with the examples in this study. Selected Match Question Fish weight Water temperature B. Independent variable fish diet fish size (length) A. constant water pH A. constant A. constant C. Dependent variable All Answer Choices A. constant B. Independent variable C. Dependent variable

Explanation / Answer

Answer:

1) Based on the given information: The objective of experiment is to determine the effect of temperature on growth rate of a particular species of fish. The variables that are mentioned are water temperature and fish growth measurement over time.

Independent variable is the one which is controlled in an experiment. Dependent variable is the one that is being tested or measured in an experiment. Fish growth as a function of water temperature can be measured in terms of both length and weight. in a controlled experiment, other conditions are kept constant. So the correct options are:

2) The objective of experiment is to determine the effect of logging on small understory plants. Effect of light reaching the ground on growth of understory plants.
