Question

what is the dependent variable in this experiment? a fish weight b tank brand c amount of food d amount of water

Explanation:

In an experiment, the dependent variable is the one that is measured or observed and depends on the independent variable(s). Here, fish weight (option A) is likely the outcome being studied, as it would depend on factors like amount of food, water, or tank brand (which are independent or controlled variables). Tank brand (B), amount of food (C), and amount of water (D) are more likely independent or controlled variables that might affect the fish's weight.

Answer:

A. fish weight
