Why would it be pointless for reptiles to sit on their eggs to incubate them as birds do? (2 points) reptiles have teeth with which to defend their eggs from predators, so they do not need to hide the eggs. reptiles have no feathers and cannot cushion the eggs from bumping into each other without them. reptiles are ectotherms and cannot raise their body temperature above that of the environment. reptile eggs are not amniotic and have no shell, so sitting on them would crush them.

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.
