Answers

A prevailing wind coming from the North Pole would each type of prevailing wind have on the land it crosses.

What are the three different kinds of prevailing winds?

The trade winds, prevailing westerlies, and polar easterlies are the three predominant wind belts connected with these cells.

Although prevailing winds frequently come from the north sea and provide moisture to the land, they can also bring moisture to the land. There is no moisture or water involved when wind comes from a land location. This means that the winds bring more dry air into the atmosphere, reducing the likelihood of rain.

Genetic recombination, production of more offspring than can survive, and struggling with the challenges of the environment are all concepts associated with.

Answers

The concepts of genetic recombination, the production of more offspring, and surviving the challenges of the environment are associated with natural selection.

Natural selection and evolution

Natural selection describes the adaptation and modification of populations of living things.

Members of a population are inherently varied, which means they differ in certain respects. Because of these differences, some individuals can be better suited for their surroundings, which is very important in enhancing the chances of surviving and increasing the chances of reproducing as well, thus passing on their adaptive features to their progeny. These beneficial features grow increasingly prevalent in the population over time. 

The differences in traits can be explained by changes in the structure of the molecules that make up genes (DNA) are known as mutations. Mutations can occur at random (for example, when replicating cells make a mistake while duplicating DNA) or as a result of exposure to toxic substances or radiation in the environment.

Mutations can be damaging, neutral, or even beneficial, leading to the development of a new, beneficial characteristic. Mutations can be handed on to children when they arise in germ cells.

These processes are all important for the evolution of species.
