Answer:

The correct answer is - C. The amount of folic acid is the independent variable, and the DNA synthesized is the dependent variable.

Explanation:

DNA is the genetic material of most of the living organisms. In this question, Joe wants to study to see the effect of folic acid on the synthesis of the DNA. Folic acid ae the essential nutrients or vitamin for the synthesis of nitrogen bases of the DNA that are purines and pyrimidines. A dependent variable and an independent variable are two important part of any experiment.

A dependent variable is a variable being tested and measured. In the experiment Jon is conducting, the amount of DNA becomes a dependent variable that is being tested and measured in the presence of folic acid.  And folic acid is the independent variable tested to check the formation of DNA in bacteria.

Thus, the correct answer is - C. The amount of folic acid is the independent variable, and the DNA synthesized is the dependent variable.

Δ The roots of the legumes undergoes symbiotic association for the intake of nitrogen. They form nitrates. So these plants help in transferring solid nitrate to water nitrate

Δ Animal wastes has nitrates. So these nitrates along with rain water can go to rivers

Δ The lightening strikes contain nitrogen which is converted by plants during nitrogen cycle into nitrates which then eventually goes into water
