Question

practice it! which of the following is an appropriate dependent variable for the experiment? the exposure to ultraviolet light the amount of virus killed the rate of viral infection the temperature of the environment

Explanation:

A dependent variable is what is measured and affected during an experiment. Here, the amount of virus killed is likely to be affected by other factors like exposure to ultraviolet light. Exposure to ultraviolet light is more likely an independent variable. The rate of viral infection may be related but not as directly relevant as the amount of virus killed in the context of an experiment focusing on virus - killing. The temperature of the environment is also likely an independent or controlled variable.

Answer:

the amount of virus killed
