DNA-RNA hybridization is a technique used to determine the relatedness among different species. during hybridization scientists combine a single strand of dna from two different species they heat these combined strands in small increments and observe the temperatures at which most of the strands in the sample separate scientists compare the differences in separation temperature indicates fever base pair similarities between each organisms the table shows data for six species which pair of species is the most closely related?

A. Species 4 and 5
B. Species 5 and 6
C. Species 2 and 4
D. Species 2 and 6

You decide that the introduction should also discuss the extremophiles that are referred to as the archaea. these single-cell organisms are considered "extremophiles" due to their ability to survive and reproduce in environmental conditions that would be hostile for most living organisms. archaea species have been isolated from highly acidic sulfur springs, ocean floor thermal vents with temperatures that exceed boiling, and subarctic ice well below freezing. while still considered to be prokaryotic, the archaea have numerous differences that place them apart from the bacteria. choose the characteristics that separate the archaea from other prokaryotic cells. select all that apply. view available hint(s) select all that apply. archaea lack true peptidoglycan in their cell walls. the morphology of the cell is rigid and is geometric in shape, similar to a sphere or cylinder. the cytoplasmic membrane lipids of archaea have branched or ringform hydrocarbon chains. all currently identified and characterized archaea have been linked as the causative agent to an animal or human disease.
