2) Micah and Taylor investigate the effect of tap water and spring water on the growth of plants. They grew two plants of the same type and size in separate containers. Every three days, they

added the same amount of tap water to one plant and the same amount of spring water to the

other. Describe an action that would best improve the reliability of their results?

To improve the reliability of the results, the nutritional component of each category of water must be tested and recorded.

Second, the experiment should be carried out under greenhouse conditions.

The above actions will afford more control. When an experiment is controlled, it means that except for the dependent variable, all other variables are kept constant by the scientist.

By performing the experiment under greenhouse conditions, the kind of water the plants receive, temperature and other biotic actors are kept within measurable limits thus increasing the reliability of the results.

Cheers!

the answer is frequency

i am positive it is c. condensing but i may be wrong
