<h2>Answer:</h2>

mechanism: the process of evoluton .

Evolution is the process by which veriety of modern organisms have descended from ancient ancestors. Evolution is responsible for both the remarkable similarities of all 0rganisms and the amazing diversity of that organisms but exactly how does it work? Fundamental of the process of evolution is genetic variation upon which selective forces can act in order for evolution to occur.

Examines the mechanisms of evolution focusing on:

•Decent : the genetic differences that are heritable and passed on to the next generation successfully.

• mechanisms of change: Mutation, migration (gene flow), genetic drift, and natural selection are act as mechanism of change .

• The random nature of genetic drift and their effects .

• How variation, differential reproduction, and heredity result in evolution natural selection .

• How different species can affect each other's evolution through co-evolution.

All of these mechanisms can cause changes in the frequencies of genes produce change in in populations, and so all of them are mechanisms of evolutionary change. However, natural selection and genetic drift (genetic flow) cannot operate unless there is genetic variation among organisms.

Answer:

A season of extra rain

Explanation:

A prarie can be described as a habitat which is abundant in grasses. Although some type of shrubs and flowering plants can also be found on this land, grass can be seen abundantly in such ecosystems.

If a season with extra rain occurs in the prarie habitat, then there will be a production of more grass on this land. As a result, the rabbits will have more food to feed on. Hence, a season of extra rain will increase the carrying capacity for the rabbits.

Which of these are the two major sources of nitrate pollution in rivers?

nikklg [1K]

Answer:

The correct answer is c. animal wastes and fertilizers.

Explanation:

Two major sources of nitrate pollution are farming and breeding activities. There are also certain industrial activities involved in nitrate pollution, but in general, these industries are related to agriculture.

The indiscriminate use of fertilizers for several years in intensive productions produce high nitrate concentration in soil and consequently elevate the risk of nitrate lixiviation.

Breeding animals produce nitrate pollution by their wastes, which accumulate and are not treated. These wastes include flesh, hair, feathers, skin, fat, liquids, excrements, among others. These wastes are an important source of nitrate.

In many cases, animal wastes are used by farmers as organic matter to improve their production. But excessive and incorrect use of it might produce severe damage in water sources.

What type of molecule speeds up chemical reactions in living things?

iren [92.7K]

The best answer is B - Proteins.

Proteins make up enzymes, or to put it another way enzymes are made up of protein. It is enzymes that speed up the chemical reactions. Enzymes are organic catalysts, substances that speed up a (biochemical) reaction but do not take part in the reaction and remain unchanged at the end of the reaction.

In man, there are many enzymes. The majority of these are found in the digestive system where they greatly aid the process of food breakdown from complex molecules to simple molecules. Examples include salivary amylase found in saliva, which begins the gradual breaking down of starch into glucose right from the moment food is placed in the mouth and mixed with saliva. Pepsin in the stomach breaks down protein.
