Water bears are microscopic animals. When water bears are exposed to a vacuum of space, about 30% of
them can survive.
A scientist is doing an experiment on water bears and vacuum exposure.
Which option is a prediction that relates the outcome of the scientist's experiments with probability?
The scientist thinks water bears can survive vacuum exposure because they have little water in their
bodies.
The scientist thinks that other animals can also survive vacuum exposure.
The scientist thinks that under some conditions, up to 40% of the water bears can survive.
O
The scientist thinks that there is a 15% chance that he will receive funding for more research.

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.
