Nitrogen forms NUCLEOTIDES that are part of DNA, as well as amino acids, which help build proteins. Nucleotides are building blocks of DNA.
<h3>Nucleotides and DNA</h3>
Deoxyribonucleic acid (DNA) is a double helix molecule composed of two long strands of building blocks called nucleotides.
In DNA, there are four types of nucleotides that contain different nitrogenous bases: Adenine, Cytosine, Guanine and Thymine.
The nitrogenous bases are composed of nitrogen and they are fundamental to form nucleotides (nucleotides consist of one nitrogenous base, one sugar and one phosphate group).

Explanation:
<span>The independent variable is the variable that does not change despite inputs. In this experiment, the independent variable is the color of mashed potatoes. The control group is what the experimental group is measured against to determine how much change there is. Plain potatoes is the control group. Number of samples is how many different opinions are taken into account. In this instance, the number of samples is equal to the number of students, or 100. There are no repeated trials. She only did the experiment one time.
The hypothesis is what the experimenter believes will happen. Gloria did not state the hypothesis for the experiment. She could have said, "I believe that students will choose colored mash potatoes than plain."
This experiment can be improved by repeating the experiment at more schools. Also, it can be improved by increasing the number of students tested.</span>
