<span>The natural selection.
Natural selection is the differences in survival and reproduction as the consequence of differences in phenotypes.
In natural selection, genotype variations that will increase the chance of survival and reproduction of some organism are preserved and will be inherited. So genotypes variations are responsible for phenotypes and, thus, help the survival of species in a particular location.</span>
Answer: The correct answer is option C
Explanation:
Bombay phenotype refers to a rare genetic trait in which a person appears as blood group O even in presence of functional A, B, or AB alleles.
It is because of recessive mutation that occurs in other locus, that is, FUT1 gene. Normal gene produces H antigen or protein in the cell. This antigen is essential for the final expression of the ABO alleles.
If a person is homozygous recessive then he or she is not able to produce H antigen due to which the blood group appears as O.
However, if a person carries even a single functional copy of FUT1 gene, that is, heterozygous or homozygous then he or she can efficiently produce H antigen and then ABO alleles are expressed accordingly.
Thus, option C contains incorrect statement.
Dichotomy : the division of between two things
Answer:
The correct answer is "preservation of wetlands".
Explanation:
Wetland are areas of lands that are saturated with water, usually comprised by marshes or swamps. Preservation of wetlands help to reduce the risk of floods because wetlands temporarily store and slow the release of stormwater. It has been reported that areas where wetland have been lost, the chances of flood increases by as much as 80 percent. The government of a flood-prone region would likely reduce the risk of floods by preserving its wetlands.
