<span>The two advantages are: 1) Modern high yield agriculture has been able to keep pace with the ever increasing population by achieving a much greater productivity than times of old. 2) With the discovery of hybridization and plant genetics modern high yield agriculture is able to produce a hybrid of many crops with overly nutritious fruit within the shortest possible time for man's consumption. There are many harmful environmental effects of agriculture including but not limited to Land conversion and habitat loss. Wasteful water consumption. Soil erosion and degradation to mention a few. Soil erosion is the wearing away of top layer of the soil which contains most organic, nutrient-rich materials caused primarily by water and wind. The harmful effects of soil erosion are soil compaction, low organic matter, loss of soil structure, poor internal drainage, salinisation and soil acidity</span>

1.High yield modern agriculture refers to the practice of breeding genetically modified crops or using fertilizer to increase the production yield of planted crops. Two advantage of high yield modern agriculture are:
1. Production of large quantities of planted crops.
2. Ability to select and breed plants with superior qualities.

2. Agriculture have some negative influence on the environment, the major harmful environmental impacts of agriculture are:
a.  Habitat loss: Agricultural practices present great danger to species and ecosystem. This is because, farmed areas serve as habitats for different types of wild plants and animals. Farming the areas makes these living organisms to lose their habitats and these throw the ecosystem into imbalance.
b. Soil erosion and degradation: When natural vegetation are converted into agricultural lands, the breaking up of the soil leads to erosion, which wash away the top soil and the nutrients that are embedded in it. 
c. Pollution: The chemicals that are used during farming operations, such as fertilizers, pesticides, etc. cause pollution of the air and the surrounding waters.
3. Soil erosion is the process by which the top layers of soils are carried away by agents such as wind and water. The biggest negative effect of soil erosion is the loss of top soil. The top soil is the part of the soil that contain most of the nutrients that plants use to grow. When this part of the soil is lost, the soil usually becomes non fertile. Soil erosion can also lead to water pollution. When soils are eroded from the farm lands and carried to the surrounding waters, the waters will be polluted by the chemicals such as pesticides, herbicides and fertilizers, which are had been used on the soils. This can lead to the death of the animals that are living in the waters.

A tropical forest is a type of biome that shows a little or no change of season throughout the year.

<h3>What is Biome?</h3>

A biome may be defined as a very large area or an ecosystem that is characterized by a particular type of vegetation. Examples include Tropical rainforests, Grasslands, Coral reefs, etc.

Tropical forests include rain forests, dry forests, grasslands, and savannas. The dominant plants which are found in these tropical forests are phanerophytes, epiphytes, lianas, etc.

This biome consistently faces almost the same average intensity of sunlight throughout the year. Hence, the temperature fluctuation in this biome is very mild.

Therefore, a tropical forest is a type of biome that shows a little or no change of season throughout the year.

<span> The answer is a misense mutation. In this case, the substitution of the tryosine  amino acid with cysteine in the same position in the sequence does not affect the polypeptide becasue both tryosine and cysteine are polar animo acids. If the substitution </span><span><span> in the polypeptide chain </span>was by amino acids with different properties, it would affect the folding of the protein and change its conformation hence also affect its function. </span>
