<u>Staphylococcus</u> <u>aureus</u> is a pathogen that can contaminate food if a food service worker sneezes on the food.
What is Staphylococcus aureus?
Staphylococcus aureus is a bacterium which is highly tolerant to salt, and can easily grow on food materials like meat, milk products etc.
Role in disease:
- S. aureus is found generally in soil, air and water. Research says it can also be found in nose, skin and other areas of human beings.
- Any food contaminated with this bacterium, can become toxic for consumption because the bacteria can easily multiply in the food, release toxin that can cause illness.
- Major illness caused by Staphylococcus aureus include Pneumonia, sepsis, toxic shock syndrome etc.

Acidic substance(s):
Vinegar contain acetic acid
Tomato Juice contain citric acid
Basic substance(s):
Baking Soda contains Sodium Carbonate
Neutral Substance(s):
In the process of producing sugar, the sugar cane juice is acidic but goes through a process where it's acidity is neutralized and as such the crystalline sugar ends up neutral
The answer to the above question is alleles.
<h3>What are Alleles?</h3>
The two nucleic acids in living things that are employed for conveying and storing genetic information are RNA and DNA. The genetic material in living things is called deoxyribonucleic acid (DNA), and it contains sections coding for beneficial proteins and products as well as carrying genetic information from one generation to the next. These chunks are referred to as genes.
However, genes also have a different form that is in charge of the genetic diversity in the qualities they are coding for. Allele refers to a gene's alternative or variant version. In a diploid creature like the human, each trait is encoded by genes that include contrasting pairs of alleles, allowing variation for that specific trait, i.e. two alleles for each gene. For instance, a gene with two alleles that codes for one of the human height traits includes the short variety (t) and the tall variety (T).

<h2>Answer </h2>
Neutral Variation
<u>Explanation</u>
Point mutations in noncoding regions of DNA result in neutral variation. The alleles which neither considerably sum to nor exceedingly lower from body consistency. It is the accumulation of such alleles located within a community that can be explained as expressing neutral variation. Neutral Variation implies in various alleles that are existing at an assigned genetic locus because those alleles are not distinct by natural selection.
