Which variable should be changed in an experiment to test the best conditions for bacteria to grow? the type of bacteria used th

Setler [38]

An experiment to test the best conditions for bacteria to grow is the material that the bacteria feed upon. <u>Option D.</u>

<u />

Antibacterial hand soap with different concentrations. Dependent variable bacterial growth as measured by the diameter of the zone of inhibition. Exposing Petri dishes to different temperatures can skew the level of bacterial growth they inhabit. Plant height is the dependent variable that responds to changes in the independent variable.

Sunlight is the controlling variable because each plant is exposed to the same amount of sunlight. It is the dependent variable because it measures the amount of plant growth. The dependent variable depends on the independent variable. How much plants grow depends on how much sun they receive. A continuous increase in temperature from a minimum value increases the rate of bacterial growth because the rate of metabolic reactions increases with increasing temperature.
