g Warfarin is metabolized by the CYP2C9 protein. The common allele of this gene is CYP2C9*1, and an individual with two copies of this allele metabolizes warfarin at a rate that is typical of most people. The CYP2C9*2 and CYP2C9*3 alleles are also present in European populations. Each variant allele produces CYP2C9 proteins with a single amino acid change. These changes to the DNA sequence can be described as variants.

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
