Agriculture is the leading source of pollution in many countries. Pesticides, fertilizers, and other toxic farm chemicals can poison fresh water, marine ecosystems, air, and soil. They also can remain in the environment for generations.

What are the major environmental problems caused by agriculture?

Agriculture contributes to a number larger of environmental problems that cause environmental degradation including climate change, deforestation, biodiversity loss, dead zones, genetic engineering, irrigation problems, pollutants, soil degradation, and waste.

Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.

Fossil fuels began to be used, which led to increased pollution, and the construction of factories led to the loss of habitat for many wild animals. The development of agriculture has led to the emergence of new plant varieties, domestication of animals, and disturbance of soil composition.

Therefore, some of the environmental problems caused by the agriculture and natural resource industry are well described above.

Explain the reason the Type AB and Type O blood phenotypes always have the same
genotype, whereas the Type A and Type B blood phenotypes have two possible allelic
combinations.

Answers

Answer:

Because A is co-dominant to B and O is recessive, so the genotype is the same as the phenotype. But A can have 2 genotypes because A can mask a recessive allele, which makes the phenotype A. B can also mask a recessive allele, which makes the phenotype B.

Examples

AO (genotype) = A (phenotype)

BO (genotype) = B (phenotype)
