Imagine you are listening to a series of student presentations in which the speakers hypothesize about the kinds of marine life they would expect to find in an abyssal marine zone. which hypothesis do you find most compelling?
a) autotrophic organisms like seaweed and plankton will be common, along with many larger organisms supported by these producers.
b) coral reefs and high species diversity are expected, with many kinds of fish and invertebrates.
c) large open-ocean fish will live there, like tuna, marlin, and sharks.
d) low species diversity is predicted, except around hydrothermal vents where bacteria, fish, and crabs live.

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.
