The semester final for Mr. Garcia's science class required students to design and conduct an investigation that would answer the question "Is styrofoam a better insulator than plastic?"
Which experiment would be most effective in helping students obtain evidence to use in answering this question?
100 mL of 70 °C water placed in 200 mL plastic cup
O A. 100 mL of 10 °C water placed in 250 mL plastic cup
wait 20 minutes, remeasure temperatures
50 mL of 70 °C water placed in 250 mL styrofoam cup
OB. 100 mL of 70 °C water placed in 250 mL plastic cup
wait 20 minutes, remeasure temperatures
100 mL of 70 °C water placed in 200 mL plastic cup
OC. 100 mL of 70°C water placed in 200 mL styrofoam cup
wait 20 minutes, remeasure temperatures

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.
