nirvana33 [79]

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.

You hear someone mention the molecule "amp." based on what you learned about the structure of atp and the way in which energy is
polet [3.4K]

ATP stands for Adenosine Triphosphate. This sounds like a complicated name, but when we break the name down, it's really a simple description of what makes up the ATP molecule. (***see attached pic***)

I don't know how in depth you need to know the structure of ATP, so let's keep it simple.  There are two major parts of the molecule (one is called "adenosine" and one is the "3 phosphates").  If you know that the prefix "tri-" means "3", then you can see that the name ATP is simply just telling you about the make-up of the molecule.

AMP stands for adenosine MONOphosphate. Therefore, it's two major parts are adenosine and 1 phosphate (because "mono-" means "1").

The energy from ATP comes from the bonds between the phosphates. Think of the molecule like a battery. The more phosphate bonds, the higher charged it is. Therefore, ATP has much more energy to release and power cellular functions than AMP does. AMP is actually the bi-product of the cell breaking ATP's phosphate bonds to release energy from them and power cellular functions.
