Answer:
Air pressure is the weight of air molecules.
Explanation:
Air pressure can be described as the force generated by the weight of air on the surface of the Earth. The size and number of the air molecules determine the air pressure.
When the number of molecules in the air increases, it generates more force on the Earth's surface and we say that it is regarded as a rise in the atmospheric pressure. A mercury barometer is a device which is used to measure the air pressure.

<em>Hypotonic solutions contain a low concentration of solute relative to another solution ( The cells cytoplsm) </em>
<u>Thus, when a cell in placed in a hypotonic solution, the water diffuses into the cell, which causes the cell to swell up. </u>
<em>The cell has lower solute concentration than the solution. So the solution is HYPERTONIC and the cell is HYPOTONIC. </em>
As a result, a cell that does not have a rigid cell wall, such as a red blood cell, t'will most definitely swell and burst when placed in a hypotonic solution.
No there is no selective pressure that confers an advantage to those who do taste it.
<h3>What is PTC?</h3>
Despite the fact that PTC isn't found in nature, tasting other bitter substances—many of which are toxins—that do occur naturally has a high correlation with taste sensitivity.
In order to defend themselves from being eaten, plants develop a range of harmful substances. Early humans developed the capacity to distinguish bitter tastes as a safeguard against ingesting dangerous plants. There are roughly 30 genes in humans that produce bitter taste receptors. People may taste a large variety of bitter substances because each receptor can interact with a number of different molecules.
