The answer is C: a pollutant.
Answer:
Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.
They are all mechanisms of <u>Evolution </u>and can change allele frequencies in populations
Natural selection, mutation, genetic drift and gene flow are all capable of causing varying changes in allele frequencies in a population. and these changes leads to the violation of Hardy-Weinberg assumptions
Hardy-Weinberg assumption states that; for a population to experience an unchanged allele frequencies, certain conditions must be met by the population such as ; absence of natural, random mating , absence of migration and absence of mutation.
Hence we can conclude that Natural selection , mutation, genetic drift and gene flow are all mechanisms of <u>Evolution </u>and can change allele frequencies in populations
