You are interested in studying a gene called cftr because mutations in this gene in humans cause cystic fibrosis. you have made a line of mice that lack the mouse cftr gene. these mice are unable to clear bacteria from their lungs, so they get lung disease. you put a normal human cftr gene into some of these mice and discover that the mice with the human gene are able to clear bacteria from their lungs and no longer get lung disease. from this experiment, you can conclude that:

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.

How is the carbon cycle related to global warming ?

Hershey and chase confirmed that dna, not protein, was the genetic material. how do the results of their two experiments support this conclusion?
