Ques:Answer the following question given this paragraph: 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. Q: Respiration rate correlates with what? Choices: - size - heat - pressure - energy use A:

Ans:energy use

Ques:Answer the following question given this paragraph: The menstrual cycle includes events that take place in the ovary, such as ovulation. It also includes changes in the uterus, including menstruation. Menopause occurs when menstruation stops occurring, usually in middle adulthood. Q: At what time of life does menopause occur? Choices: - old age - young adulthood - adolescence - in middle adulthood A:

Ans:in middle adulthood

Ques:Answer the following question given this paragraph: Sometimes two different minerals have the same chemical composition. But they are different minerals because they have different crystal structures. Diamonds are very valuable as gemstones because they are very pretty and very hard. Graphite is the "lead" in pencils. It's not hard at all! Amazingly, both are made just of carbon. Compare the diamond with the pencil lead ( Figure below ). Why are they so different? The carbon atoms in graphite bond to form layers. The bonds between each layer are weak. The carbon sheets can just slip past each other. The carbon atoms in diamonds bond together in all three directions. This strong network makes diamonds very hard. Q: Why are two different minerals considered different though they have the same chemical composition? Choices: - different linear structures - different molecular structures - different rods structures - different crystal structures A:

Ans:different crystal structures

Ques:Answer the following question given this paragraph: In warmer regions, plants and bacteria grow faster. Plants and animals weather material and produce soils. In tropical regions, where temperature and precipitation are consistently high, thick soils form. Arid regions have thin soils. Q: What happens to growth of plants and bacteria in warmer regions? Choices: - they mutate - they are stunted - they grow slower - they grow faster A:

Ans:
they grow faster
