If it’s a yes or no question then yes because they spread through organisms. there are many organisms in the water that bacteria can spread through
There is variation within the population, due to a mutation. The selection pressure is the drug. The microbes that have the advantageous gene which makes them resistant to the drug are selected for, and reproduce passing on the gene, increasing its allele frequency within the population over time. However, the microbes that do not have the advantageous gene, cannot survive and their number decreases within the popullation.
Answer:
DNA mutation causes genetic variation by altering the genes of individuals in a population. Gene flow leads to genetic variation as new individuals with different gene combinations migrate into a population.
The flow of individuals in and out of a population introduces new alleles and increases genetic variation within that population. Mutations are changes to an organism’s DNA that create diversity within a population by introducing new alleles.
The advantageous proteins that build larger molecules help prolong life life. If there is better survival and reproduction, it is more likely to pass onto the next generation. If it continues to be advantageous, the sequence of them change to support the life of the current species.
Answer:
the answer is D: the the preservation of species
