Balance the ruler so there is an equal length on both sides of the fulcrum (at the 6β mark).
Put a nickel at the one inch mark on the ruler. Record your observations in the data table.
Keep the nickel at the 1β mark. Drop a quarter on the end of the opposite end of the ruler from about 12 inches in height. Measure the distance from the end of the ruler to where the nickel lands. Record your results.
Repeat this 3 times.
Now move your fulcrum to the 9 inch mark and repeat steps 2-4.
Now more your fulcrum to the 12 inch mark and repeat steps 2-4. Which causes the nickel to fly farther? Which takes more force?

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.
