Answer:
Water erosion refers to the removal of the top most or surface layer of soil by the flow of water. The long term effect of water erosion can be because of drastic rain fall and may be because of flood. These two reasons can adversely effect the human life. The water erosion is responsible for the removal of fertile layer of soil, therefore, the region will not be appropriate to grow vegetation. The long term effect may result in stagnation of water, therefore, long time is required so that the region gets dried. The long term accumulation of water over an agricultural field can spoil the crop production.
Prevention that can be taken to reduce long term effect of water erosion:
1. Plantation of long root bearing trees over flood prone regions and around the agricultural field: This will allow the trees to tightly hold up soil and prevent it's erosion.
2. Add rocks over the soil: In an agricultural field or flood prone area, the rocks will act as barrier for the movement of run off water, hence, will prevent water erosion. It will increase the absorption of water by soil.
3. Building of walls: This will also act as a barrier in a flood prone region and will prevent the water being added up to the agricultural land.
4.Remove soil compaction: If the soil compaction of the effected region is removed, the water retention property of the soil can be improved. Machines, animals and humans can be used for this purpose to remove the compaction of upper layer of soil.

How do the genes in our DNA influence our characteristics? For example, how can a gene determine
whether a person is an albino with very pale skin and hair?
Basically, a gene is a segment of DNA that provides the instructions for making a protein, and
proteins influence our characteristics. This chart describes how two different versions of a gene result
in two different versions of a protein which in turn can result in either normal skin and hair color or
albinism.
DNA Protein Characteristic
Version of the gene that provides
instructions to make
normal protein enzyme
Normal enzyme that makes the
pigment molecule in skin and
hair
Normal skin and hair
color
Version of the gene that provides
instructions to make
defective enzyme
Defective enzyme that does
not make this pigment
molecule
Albinism (very pale
skin and hair)
A gene directs the synthesis of a protein by a two-step process.
The first step is transcription of the gene in the DNA.
Transcription produces a messenger RNA (mRNA) molecule.
The second step is translation of the mRNA molecule.
Translation produces a protein molecule.
During transcription, the sequence of
nucleotides in a gene in the DNA is
copied to a corresponding sequence
of nucleotides in mRNA.
During translation, the sequence of
nucleotides in the mRNA determines
the sequence of amino acids in the
protein.
After translation, the sequence of amino acids in the protein determines the structure and function of
the protein. Differences in protein function can influence characteristics such as normal skin and hair
color vs. albinism.
