Answer 2

If the temperature of the room is increased, then the bacteria will grow faster. Temperature is the independent variable

Explanation:

• An independent variable is a variable that can be altered or manipulated has a direct effect on the dependent variable. A dependent variable is a variable that is measured or tested in the experiment. It is dependent on the independent variable.

• The growth of bacteria is affected by temperature. When the temperature gradually increases from their minimum temperature, then the growth rate of bacteria increases because the metabolic rate increases with the temperature rise. This temperature is known as the optimal temperature, where the growth rate is maximum.
• When the temperature is raised above optimal, the growth rate abruptly declines and completely ceases the growth of bacteria upon reaching maximum temperature.
• Here, the temperature is the independent variable. When the temperature is altered, there is a change in bacterial growth. Bacterial growth is a dependent variable as it depends on the temperature to increase the growth.
