Answer:

A. What length of time is best to use for the firing of pottery to make it strong?

Explanation:

Point A

What length of time is best to use for the firing of pottery to make it strong?

This is a scientific question for Nancy since while making pots from black mud, it is very important to know how much time is required to fire the pot in order to make it strong. Because if we fire it for too long the pot may be become too hot and will eventually crack. While if we fire for less time it will not become hard enough to withstand its shape. So knowing the proper time to fire the pot is very essential in pottery.

Point B, Point C and Point D are not scientific investigations since it includes ones likes and dislikes, quantities and numbers of goal scored which is not scientific.

Hence, option A is the correct answer.

Artyom0805 [142]

If a drug slows down central nervous system activity while increasing the activity of the main inhibitory neurotransmitter in the brain, then it is most likely to be a Depressant.

<h3>How do neurotransmitters work and what are they?</h3>

Chemical messengers are called neurotransmitters to facilitate communication between nerve cells. Serotonin, dopamine, glutamate, and acetylcholine are a few of them. Numerous processes are controlled by neurotransmitters, including mood, sleep-wake cycles, and appetite.

<h3>DEPRESSANTS</h3>

These medications, which are sometimes known as "downers," are available as liquid or colored pills and capsules. As they are intended to lessen the symptoms of mental illness, some medications in this class, including Zyprexa, Seroquel, and Haldol, are referred to as "major tranquilizers" or "antipsychotics." Xanax, Klonopin, Halcion, and Librium are examples of depressants that are frequently referred to as "benzos" (short for benzodiazepines).

When antibiotics attacks a bacteria first the growth of bacteria is stopped and the bacteria will become unable to divide and spread throughout the body via the bloodstream and aortic arteries. An antibiotics' main job is to stop the growth of bacteria and other foreign entities inside our body, such as a virus, fungal spore, parasites, and other dangerous and potentially deadly protozoa, so as to prevent the body from harm that may be fatal.

On cellular level, antibiotics chemically damage the bacteria or targeted organism's DNA and alter it in such a way that they will become unable to divide any further and thus become unable to reproduce and eventually die off as the white blood cells engulf the decaying organism's body, so it doesn't become dangerous.
