<h3><u>Answer;</u></h3>
<em>John Doe is convicted of murder based on DNA evidence found at the crime scene.</em>
<h3><u>Explanation</u>;</h3>
- <em><u>DNA molecules are the molecules that carries the genetic information in organisms. </u></em>These molecules are specific to each organism, thus the DNA of each organism is different from that of another organism.
- <em><u>The concept of DNA specificity is used in criminal investigation in a crime scene where DNA materials in the scene is analysed to identify the criminals.</u></em> The analyzed DNA materials is compared to the DNA of the suspects and if a match is identified then a criminal is identified.

Answer:
Most human cells are diploid, and only the gametes (i.e., the sperm and egg cells) are haploid. Haploid cells contain half the number of chromosomes as diploid cells. A human diploid cell contains a total of 46 chromosomes (2n = 46), so a haploid cell will contain 23 chromosomes (n = 23).
A water molecule, because of its shape, is a polar molecule. That is, it has one side that is positively charged and one side that is negatively charged. The molecule is made up of two hydrogen atoms and one oxygen atom. The bonds between the atoms are called covalent bonds because the atoms share electrons. The hydrogen atoms have one electron each.
Because they share those electrons with the oxygen atom, the electrons tend to stay close to the oxygen atom and the outside of the hydrogen atom tends to be positively charged. The oxygen atom has eight electrons. Most of those tend to stay away from the hydrogen atoms and cause the outside of the oxygen atom to have a negative charge.
<span>When two water molecules get close together, the polar forces work to draw the molecules together. The oxygen atom of one water molecule will bond with several hydrogen atoms of other water molecules. These bonds are called hydrogen bonds.</span>
