Astudent poured a solution of bromothymol blue (bmb) into three test tubes. (bmb turns yellow in the presence of co2.) then he placed an aquatic plant in two of the test tubes, as shown in the diagram (you will see the diagram when you are taking the test). he placed a stopper on each test tube and placed them all in the dark for two days. predict what change of color, if any, would occur in each of the test tubes. explain your answer. (2 points extra credit): describe what color change would occur in each tube, if any, if the experiment were done in the light. explain your answer.

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.
