An example of an endothermic process is Boiling. 
An endothermic reaction is any chemical reaction that absorbs heat from its environment. Boiling is a course by which a liquid changes into a vapor when it is heated to its boiling point. The shift from a liquid phase to a gaseous phase happens when the vapor pressure of the liquid is of the same level to the atmospheric pressure exerted on the liquid.

What do high and low air pressure systems mean in terms of density?
Arada [10]

<span>There are two physical differences between Low pressure systems and </span>High pressure systems.

First, is the circulation surrounding them.

Secondly, is the atmospheric motion that they cause.

Low pressure systems circulate counter-clockwise. High pressure systems circulate clockwise. These "motions" are the building blocks in our atmosphere. They give us our weather.

A Low’s counter-clockwise circulation forces air upward (ultimately resulting in condensation, cloud formation and ultimately precipitation). A High’s clockwise circulation causes a sinking motion in the atmosphere, resulting in fair/clearer and often sunnier skies.

Doss [256]

Answer:

Artificial selection is non-random whereas natural selection, and sexual selection are random selection.

Explanation:

Artificial selection is considered non-random whereas natural selection, and sexual selection are considered as random selection because in Artificial selection, humans select the mating animals in order to acquire the desired characteristics and features in the offspring while on the other hand, natural selection, and sexual selection are happen randomly without the intervention of humans, it occurs naturally so we can conclude that artificial selection is non-random whereas natural selection, and sexual selection are random selection.
