Agroup of biology students tests the growth of bacteria under different conditions. the students apply the same amount of bacteria to identical petri dishes enriched with nutrients, then place each plate at a different temperature. the bacteria are allowed to grow for three days, after which the number of bacterial colonies on each plate is counted. what is the dependent variable in this experiment?

Dependent variable in this experiment is temperature.

A dependent variable is the variable being tested and measured in a scientific experiment. It is sometimes called the responding variable. The dependent variable depends on the independent variable.

In the above experiment the growth of bacteria is dependent on temperature as you change the temperature their growth differs so the temperature is dependent variable.
