Q: Q: What do obligate aerobes need to live? Read this paragraph and choose the correct option from the provided answers: Organisms that are obligate aerobes need oxygen to live. That is, they use oxygen as a terminal electron acceptor while making ATP (see the "Cellular Respiration" concept). Humans are obligate aerobes, and so are Mycobacterium tuberculosis bacteria. M. tuberculosis causes tuberculosis (TB). Obligate aerobes are found only in places with molecular oxygen. Choices: - blood - acid - dioxide - oxygen A:
A: oxygen

Q: Q: What are mid-wavelength electromagnetic waves commonly referred to as? Read this paragraph and choose the correct option from the provided answers: Mid-wavelength electromagnetic waves are commonly called light. This range of electromagnetic waves has shorter wavelengths and higher frequencies than radio waves, but not as short and high as X rays and gamma rays. Light includes visible light, infrared light, and ultraviolet light. If you look back at Figure above , you can see where these different types of light waves fall in the electromagnetic spectrum. Choices: - gamma rays - x-rays - electricity - light A:
A: light
