Answer the following question given this paragraph: A space station was established far from the gravitational field of Earth. Extended stays in zero gravity are not healthy for human beings. Thus, for the comfort of the astronauts, the station is rotated so that the astronauts feel there is an internal gravity. The rotation speed is such that the apparent acceleration of gravity is . The direction of rotation is counter-clockwise. If the radius of the station is , what is its rotational speed, ?. Q: Extended stays in zero gravity are not healthy for human beings. thus, for the comfort of the astronauts, the station is rotated so that the astronauts feel there is what? Choices: - revealed gravity - still gravity - Fixed Gravity - internal gravity A:
(Answer)
internal gravity

Answer the following question given this paragraph: The many steps in the process of aerobic cellular respiration can be divided into three stages. The first stage, glycolysis, produces ATP without oxygen. Because this part of the cellular respiration pathway is universal, biologists consider it the oldest segment. Note that glycogen and fats can also enter the glycolysis pathway. The second stage is the Krebs Cycle, and the third stage is the electron transport chain. It is during the third stage that chemiosmosis produces numerous ATP molecules. Q: Glycolysis, the krebs cycle, and the electron transport chain are stages in what process? Choices: - cell death - reproduction - mitosis - aerobic cellular respiration A:
(A).
aerobic cellular respiration

Defining traits of mammals are fur or hair and mammary glands. Mammals are noted for the many different ways they can move and their specialized limbs. Q: Mammals are endothermic vertebrates that have four limbs and produce what type of eggs? Choices: - gymnoic - umbilical - epithelial - amniotic A:

Ans:amniotic
Answer the following question given this paragraph: Surface currents are extremely important because they distribute heat around the planet. Surface currents also have a tremendous influence on climate around the globe. Q: Which currents distribute heat around the planet and have a large impact on climate? Choices: - air - electrical - wind - surface A:
surface
