Soil erosion is a process where the top soil layer is washed away because of the effects of water or wind. An agricultural area

Lana71 [14]

Answer: Plant vegetation so that their roots hold the soil firmly.

Build walls around the farm area.

Add natural fertilizers to the soil.

Soil erosion is a process of removal of top layer of soil which get sediment at some other place due to the affect of agents like wind and water. The superficial upper layers of soil are rich source of nutrients and organic matter and active region for germination of seeds and plant growth. Soil erosion removes these superficial layers making soil less fertile or not fertile and less useful for plant growth.

Plants growing in a vegetation have roots which can hold the soil and will prevent soil erosion from wind and water or any other agent. Building of walls around the farm area will prevent flood water to get inside the farm area and hence, prevents soil erosion by water. Addition of natural fertilizers to the soil adds up nutrients to the soil which facilitate plant growth and plant roots hold the soil therefore, prevents soil erosion.

Sauron [17]

A pedigree shows the genotypes of the family members
in autosomal recessive disorders, the diseased genes are inherited from the parents. For the person to get the disease both diseased genes should be there in the genotype as its a recessive disorder.
the dominant gene - H
recessive gene - h
for a person to get a disease, genotype should be hh, as its autosomal recessive. If the person is normal he/ she could have the genotype HH or could be Hh and thats called a carrier.
the offspring will receive one gene from the mother and one from the father

MAXImum [283]

<span>The specific heat of the metal is 0.5 cal/ (0C.g). This means the energy needed is 0.5 cal to raise the heat of 1 gram of metal by 1 degree C. Therefore, the energy needed to raise 100 g of the metal by 20 degrees C is:
0.5 * 20 * 100 = 1000 cal.
