2. Why do scientists often use thermoacidophile group of archaebacteria for research?

Sulfolobus quinone is used to shuttle electrons from a membrane-bound hydrogenase to the sulfur reductase.

Explanation:

the darker peppered moth species were favored due to the fact that the industrial revolution had made all the nearby trees a darker color instead of white.

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
