A mutation refers to the random changes in the genome of the organisms. Being a random event, it is not possible to calculate the effect of mutations on the allele frequency of a population.
Genetic drift refers to changes in the allele frequency by chance event alone. Since the occurrence of chance events can not be predicted, the resultant changes in the allele frequency of the population can not be calculated.
All of the following are forms of energy a living organism can use except nuclear energy. Nuclear energy is the use of nuclear reactions that release nuclear energy to generate heat ( thermal energy is being transferred between two objects).Exposure to any radioactive material and energy is bad because the nuclear energy damages human body and cells.
