Box Turtles. Suppose you want to know how many box turtles there are in a wooded park. On the first day, you hunt through the woods and capture 18 turtles. You place a spot of paint on each turtle’s shell and release all turtles back where you found them. A week later you return, and with hard work and effort, catch 50 turtles. Of these, 10 are marked and 40 are unmarked. Since you know how many turtles you marked, sampled, and recaptured, you can estimate the size of the whole population. By the definitions above, M =18 marked and released; S = 50 in the second sample; and R =10 recaptures.

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.
