Here, an enzyme such as DNA polymerase catalyzes a reaction in a first step and then checks that the product is correct in a second step. This two-step process results in average error rates of less than 1 error in 100 million reactions in high-fidelity mammalian polymerases.ere, an enzyme such as DNA polymerase catalyzes a reaction in a first step and then checks that the product is correct in a second step.

The correct answer is Mountains. Mountains can alter wind flow and create a rain shadow effect. A mountain is a large landform and is high surrounding a limited area. It is generally steeper and higher than a hill. Comments.
Furthermore, agreement is widespread that these changes may profoundly affect atmospheric water vapor concentrations, clouds, precipitation patterns, and runoff and stream flow patterns. Global climate change will affect the water cycle, likely creating perennial droughts in some areas and frequent floods in others.urthermore, because of warmer temperatures, more precipitation is falling as rain rather than snow. One expected effect of climate change will be an increase in precipitation intensity: a larger proportion of rain will fall in a shorter amount of time than it has historically.
