Quizlet: Aspirin is known to cause stomach ulcers when taken too often owing to its inhibition of COX-1, which is constitutively expressed, and the prostaglandin product signals for localized cellular housekeeping, not pain and swelling. In contrast, COX-2 is induced (produced) when, for example, you get cut or punched in the face; then its prostaglandin product signals pain and swelling. Identify the shape-based structural features and electostatics-based structural features that would lead to a selective COX-2 inhibitor to avoid the side effects of aspirin. Don't forget to consider the intracellular location of these peripheral membrane-bound enzymes.

Hummingbirds drink nectar from flowers, while robins eat plant seeds. what does this reduce?

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.
