Q: Q: What term refers to the balance, or equilibrium, within the cell or a body, and an organism's ability to keep a constant internal environment? Read this paragraph and choose the correct option from the provided answers: Homeostasis refers to the balance, or equilibrium, within the cell or a body. It is an organism's ability to keep a constant internal environment. Keeping a stable internal environment requires constant adjustments as conditions change inside and outside the cell. The adjusting of systems within a cell is called homeostatic regulation. Because the internal and external environments of a cell are constantly changing, adjustments must be made continuously to stay at or near the set point (the normal level or range). Homeostasis is a dynamic equilibrium rather than an unchanging state. The cellular processes discussed in both the Diffusion and Active Transport concepts all play an important role in homeostatic regulation. You will learn more about homeostasis in other concepts. Choices: - metabolism - ketosis - consciousness - homeostasis A:
A: homeostasis

Q: Q: Which scientist built the first telescope? Read this paragraph and choose the correct option from the provided answers: Humans have been making and using magnifying lenses for thousands of years. The term "telescope" was coined by the Italian scientist and mathematician Galileo Galilei (15641642). Galileo built the first telescope in 1608. His telescope used two lenses to make distant objects appear both nearer and larger. He subsequently made many improvements to telescope design. Choices: - einstein - newton - darwin - galileo A:
A: galileo

Q: Q: What type of climates are found around the equator? Read this paragraph and choose the correct option from the provided answers: Tropical climates are found around the Equator. As you'd expect, these climates have warm temperatures year round. The warm air rises at the Equator. As it rises, it cools, causing it to rain. Tropical climates may be very wet, or wet and dry. Choices: - arid - tundras - arctics - tropical A:
A: tropical

Q: Q: What organelles are known as the energy "powerhouses" of the cells? Read this paragraph and choose the correct option from the provided answers: In stage two, the pyruvate molecules are transported into the mitochondria. The mitochondria are the organelles known as the energy "powerhouses" of the cells ( Figure below ). In the mitochondria, the pyruvate, which have been converted into a 2-carbon molecule, enter the Krebs cycle. Notice that mitochondria have an inner membrane with many folds, called cristae . These cristae greatly increase the membrane surface area where many of the cellular respiration reactions take place. Choices: - proteins - atoms - carbohydrates - mitochondria A:
A: mitochondria
