Answer:
<h2><u>
Upwelling.</u></h2>
Explanation:
When winds blow at the coastline, they push the surface water offshore, so water from the below rises to the surface to fill this void. This upward movement of the water is called upwelling.
The water that is drawn from the below is usually colder, dense and rich in nutrients. It serves as a source of energy and food for the sea population like fish and other sea critters.
Theory of natural selection by Charles Darwin explains the moth appearance in England. The theory of genetics describes this as a mere shift of trait due to environmental factors.
<h3><u>Explanation:</u></h3>
Peppered moths are the moths found in England from a long time ago. The environment before the industrial revolution was pure and pollution free, which led to the growth of the white variety of moths as they were able to camouflage better with the bark of the trees from their hunters. The white trait were the parents, and fertilization between the two recessive traits gave rise to the recessive traits only.
But with the industrial revolution, the pollution increased to a huge extent, leading to deposition of smokes and soot on trees bark where white variety of the white moths got easily recognizable. This led to the black moths which now can camouflage better. Thus the nature selected black variety over white variety for better survival, and the white variety reduced dramatically.

Since the two species co-inhabit the same habitat, habitat isolation can be disregarded as a factor keeping the two species separate. There are however some other broad categories of mechanisms for <span>reproductive isolation. One is behaviour. Many birds in particular have very specific mating rituals, including mating dances, particular bird song, the development of specific mating plumage, the release of specific pheromones and the building of a particular nest structure. Another broad category is mechanical isolation. You will find that the genital organs of particular species are very specific, and preclude other close species from successfully mating. Another broad category is gametic isolation. For most species combinations, it is not possible for the gametes to fuse successfully to form a hybrid. If hybrid games do fuse, in many cases, the hybrids are sterile, such as mules for example. </span>
Potential and kinetic energy. Most object have kinetic energy. If an object is moving it is a kinectic energy. Potential energy is an energy stored in the position or arrangement of the object.
