Q: Respiration rate correlates with what? Read this paragraph and choose the correct option from the provided answers: There must be more to this story than just gas exchange with the environment. To begin to appreciate the role of oxygen inside your body, think about when your breathing rate increases: climbing a steep slope, running a race, or skating a shift in a hockey game. Respiration rate correlates with energy use, and that correlation reflects the link between oxygen and energy metabolism. For this reason, the chemical process inside your cells that consume oxygen to produce usable energy is known as cellular respiration . During this process, energy is converted from glucose , in the presence of oxygen, into numerous ATP molecules. The glucose, of course, comes from the food you eat. In biological terms, you do not eat because you are hungry, you eat to get energy. Other heterotrophic organisms also acquire glucose from other organisms, whereas autotrophic organisms make their own glucose, mostly through photosynthesis. Choices: - size - heat - pressure - energy use A:
energy use

Read this paragraph and choose the correct option from the provided answers: For most women, menstrual cycles continue until their mid- or late- forties. Then women go through menopause , a period during which their menstrual cycles slow down and eventually stop, generally by their early fifties.

Read this paragraph and choose the correct option from the provided answers: Habitats Nearly all protists exist in some type of aquatic environment, including freshwater and marine environments, damp soil, and even snow. Several protist species are parasites that infect animals or plants. A few protist species live on dead organisms or their wastes, and contribute to their decay. Choices: - greenhouse gas - habitat loss - spontaneous mutation - their decay A:
their decay
