The thorax is a very vital and important organ in the human body.

It is a structure that serves as a protective covering for organs in the body such as the lungs, the heart, some vital blood vessels e.t.c

It is false that to make a person breathe in, the volume of the chest cavity must decrease, creating a higher pressure in the thorax.

When a person breathes in, the chest cavity expands (the volume increases) and the pressure in the thorax decreases.

When a person breathes out, the chest cavity decreases in size, and the pressure in the thorax increases.

Therefore, we can see that the process of breathing in humans, follows the principle of Boyle's Law.

Boyle's law states that as the volume increases there is a decrease in pressure and as the volume decrease there is an increase in pressure.

Therefore, It is false that to make a person breathe in, the volume of the chest cavity must decrease, creating a higher pressure in the thorax.

Mia conducted a five hour experiment. She used a liquid solution. The solution decreased by 9/8 ounces every hour for 5 hours. A

sasho [114]

Given:

The solution decreased by $\dfrac{9}{8}$ ounces every hour for 5 hours.

Remaining solution at the end of the experiment = $\dfrac{99}{8}$ ounces.

To find:

The initial amount of solution.

Solution:

Let the initial amount of the solution be x.

The solution decreased by $\dfrac{9}{8}$ ounces every hour for 5 hours.

Total decreased amount $=\dfrac{9}{8}\times 5$

$=\dfrac{45}{8}$

Initial amount = Remining amount + Decreased amount of solution.

$x=\dfrac{99}{8}+\dfrac{45}{8}$

$x=\dfrac{99+45}{8}$

$x=\dfrac{144}{8}$

$x=18$

Therefore, the initial amount of solution is 18 ounces.

Enzymes can be denatured unfolded by what environmental factors

erastova [34]

Enzymes can be denatured unfolded by heat or chemicals.

<h3>What are enzymes?</h3>

Enzymes are proteins that are found in living organisms which are able to increase the rate of chemical reaction and remains unchanged at the end of the reaction.

The factors that can denature enzymes include heat and chemicals. This is because:

Higher temperatures disrupt the shape of the active site, which will reduce its activity, or prevent it from working. When the enzyme loses its shape, it is said to have been denatured.

These environmental factors can alter the pH level of the enzyme.

Therefore, for an enzyme to perform its functions, the external factors that affects it's activities must be normal and favorable.

A person eating in an asian restaurant has just finished a meal and immediately experiences burning and flushing of her skin and

Harrizon [31]

The appropriate response is Monosodium Glutamate. Unadulterated MSG is accounted for to not have a wonderful taste to the point that it is joined with an exquisite fragrance. The fundamental tactile capacity of MSG is credited to its capacity to upgrade flavorful taste-dynamic mixes when included the best possible concentration. The ideal fixation differs by nourishment; in clear soup, the joy score quickly falls with the expansion of more than one gram of MSG for each 100 mL.

Two examples of radioisotopes that can be used are carbon-14 to determine the age of fossils. Second, we can use iodine-131 to treat thyroid disease.
