<h2>Answer:
</h2>
Option a) The removal of the trees and grass during construction could result in erosion of topsoil.
<h2>Explanation:
</h2>
- Plants play a vital role in an ecosystem such as they produce oxygen, food, plays an important role in hydrological cycle(water cycle) etc.
- Deforestation in simple words, is the cutting down of forests for human use such as to clear land for construction, for fuel, for making furniture etc.
- Deforestation is one of the major reason for Soil erosion.
- Soil erosion is a natural process, but it get accelerated by deforestation.
- Plants are a natural barrier to slowdown soil erosion by slowing down the water current, as running water can also be a reason for soil erosion. Roots of the plants binds with the soil tightly and prevent it from washing away by water or taken away by air. Plant growth in less nutritious soil(Lower layers of soil) is very difficult(as the top layer contains maximum nutrients).
Result: Deforestation in forests and marsh play a major role in erosion of the top layer of the soil.
The answer is rabbit. ( A.)
Lipids contain more energy that carbohydrates because they contain more carbon to hydrogen bonds to release energy when broken.
<span>A macromolecule is a large molecule. There are four groups of macromolecules: carbohydrates, proteins, nucleic acids and lipids. Lipids consist of glycerol and fatty acids and are constructed from fats, oils, waxes, phospholipids and steroids. A lipid's function is to insulate the body and provide warmth in cold conditions. It can be concluded that a person with very little body fat gets very cold easily and a person with a lot of body fat gets very warm very quickly.<span>
