Schools are typically large buildings that require large amounts of energy to meet students' learning needs. while most of the energy is necessary to maintain safe, comfortable, and interactive learning environments for students, there are ways schools can reduce energy use without affecting students. which idea will reduce a school's energy usage the most and have the least effect on students? a) replace classroom computers with encyclopedia sets for conducting research, and replace interactive white boards with dry-erase white boards. b) cafeteria workers can cook students' breakfast and lunch meals outside on charcoal grills, instead of inside with the electric stovetops and ovens. c) remove half of the lightbulbs in each classroom and allow students can bring battery-powered flashlights to use for reading small print when needed. d) while the school is closed for holiday breaks, central heat/air systems should be turned off, and unused electrical items in classrooms should be unplugged.

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.

In an experiment examining the effects tai chi on arthritis pain, callahan (2010) selected a large sample of individuals with doctor-diagnosed arthritis. half of the participants immediately began a tai chi course and the other half (the control group) waited 8 weeks before beginning. at the end of 8 weeks, the individuals who had experienced tai chi had less arthritis pain that those who had not participated in the course.
