Why is soil important?

Answer:

1- Soil filters our water, provides essential nutrients to our forests and crops, and helps regulate the Earth's temperature as well as many of the important greenhouse gases.

2- Soil erosion is the displacement of the upper layer of soil; it is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice, snow, air, plants, animals, and humans.

3- Humans affect erosion rates in a number of ways across the globe. ... Human activities such as repeatedly walking or biking the same trails or areas can also contribute to erosion slowly over time. Forest fires also contribute to soil erosion, as vegetation previously holding the soil in place is often destroyed

4 - The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.

5 - You can reduce soil erosion by:

Maintaining a healthy, perennial plant cover.

Mulching.

Planting a cover crop – such as winter rye in vegetable gardens. ...

Placing crushed stone, wood chips, and other similar materials in heavily used areas where vegetation is hard to establish and maintain.

<u>Answer</u>: option B they have a random gene mutation that affects their fur colour.

<u>Explanation</u> :-

  • <em>Variation</em> is the phenomena which occurs in all populations.
  • These variations result in slight differences in the phenotypes of individuals .
  • These variations only arise due to <em>random mutations </em>that arise in the individuals’ genome and then can be inherited by their offspring.
  • There is always a probability of one particular trait to make the individuals survive better in the environment as compared to other trait.
  • The individuals having the trait that helps them to survive better in the environment tend to survive more and leave more progeny. This is termed as <em>survival of the fittest</em>.
  • Thus, according to the question it can be inferred that the dark fur colour arose due to a <em>random mutation </em>since it is the only source of variation. Since, in the given environmental conditions the mice having the dark fur colour were less susceptible to the predators they are better fitted to survive.
  • The dark brown fur coat mice, survive better, leave more progeny and hence, increase their population with time. However, the orginal source of origin of this trait was a random mutation. Had this mutation not occured, the dark coloured fur mice would not have been there.

So, a <em>random gene mutation affecting the fur colour made the dark coloured mice first appear in the population.</em>

The bulk of carbon dioxide is carried chemically combined with the amino acids of hemoglobin as carbaminohemoglobin in the rbcs.
natali 33 [55]
<span>The answer would be: as the bicarbonate ion in the plasma after first entering the red blood cells

Carbon dioxide will be changed into bicarbonate ion that released into the plasma. That is why the level of carbon dioxide will influence the pH of the blood. The process will produce hydrogen ion so higher carbon dioxide will result in acidosis. It is important to keep the carbon dioxide level at a certain point to prevent blood pH stable</span>
