Answer: Genetic drift may result in the loss of some alleles (including beneficial ones) and the fixation, or rise to 100% frequency, of other alleles.Once it begins, genetic drift will continue until the involved allele is either lost by a population or is the only allele present at a particular gene locus within a population. ... Genetic drift can result in the loss of rare alleles, and can decrease the size of the gene pool.
Explanation:
A scientist designed an experiment to test the effect of temperature on bacterial growth. The independent variable in this experiment was temperature.
<h3>What is the bacterial growth?</h3>
The outcomes display that microbes have a better increase price at 20, 25 and 30°C and 30°C than at 3°C. In general, an boom in temperature will boom enzyme pastime. But if temperatures get too excessive, enzyme pastime will reduce, and the protein (the enzyme) will denature.
General, the better the temperature, the greater without problems microorganisms can develop as much as a sure point. Very excessive and coffee temperatures each impede the enzyme strategies microorganisms rely on to survive.
