What is represented by<br> region on the sound<br> wave
elena-s [515]

Answer:

Compressions and Rarefactions

<em>A vibrating tuning fork is capable of creating such a longitudinal wave. As the tines of the fork vibrate back and forth, they push on neighboring air particles. The forward motion of a tine pushes air molecules horizontally to the right and the backward retraction of the tine creates a low-pressure area allowing the air particles to move back to the left.</em>

Explanation:

These regions are known as compressions and rarefactions respectively. The compressions are regions of high air presure while the rarefactions are regions of low air pressure.

<em>Sound waves can also be shown in a standard x vs y graph, as shown here. This allows us to visualise and work with waves from a mathematical point of view. The resulting curves are known as the "waveform" (i.e. the form of the wave.) The wave shown here represents a constant tone at a set frequency.</em>

DNA polymerase is an enzyme that synthesis DNA and its main function is to make DNA from nucleotides which is the building block of DNA. It is essential for DNA replication and work in pairs by creating identical DNA strands from the original DNA molecule. DNA copies are created by pairing the nucleotides to each bases present in the DNA molecule.The bases are thymine, cytostine,guanine, and adenine, the pairing occur with any of the above combinations forming two pairs respectively.

Rus_ich [418]

Answer:

e. staphylococcal enterotoxin

Explanation:

Staphylococcal enterotoxin is a toxin that is produced by the bacteria Staphylococcus aureus. It is a toxin found inside the gastrointestinal tracts of the human body which is why it is called an enterotoxin and it results in food poisoning when consumed by humans.

Staphylococcal enterotoxin is proteinous in nature and it can be found on dairy products such as milk or cheeses that have been contaminated by Staphylococcus aureus.

After consumption of the contaminated milk or cheeses, the person begins to experience symptoms of nausea, diarrhea as well as vomiting.

Staphylococcal enterotoxin is a very heat stable toxin which means even though you heat up a food contaminated with this toxin, the bacteria may die by the toxins would still remain in the food.

The best way to avoid food poisoning by Staphylococcal enterotoxin is to avoid eating contaminated foods.
