Look at the spectrum of Star 1 which is moving towards Earth and the spectrum of Star 2 which is moving away from Earth. The band in the middle represents the spectrum of a motionless light source Which of these is a correct inference that can be draw from the observation of the three spectrums?
The spectrum shifts towards the red region when the star moves towards Earth.
The spectrum shifts towards the blue region when the star moves towards Earth

The spectrum is identical for stars moving away from Earth and stars moving towards Earth.

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.
