Ques: Q: The fast motion of gas particles gives them a relatively large amount of what energy? Read this paragraph and choose the correct option from the provided answers: Gas particles are in constant rapid motion in random directions . The fast motion of gas particles gives them a relatively large amount of kinetic energy. Recall that kinetic energy is the energy that an object possesses because of its motion. The particles of a gas move in straight-line motion until they collide with another particle or with one of the walls of its container. Choices: - residual energy - Potential energy - Chemical energy - kinetic energy A:
Ans: kinetic energy

Ques: Q: What trophic level are secondary consumers (which eat primary consumers) considered to be? Read this paragraph and choose the correct option from the provided answers: Trophic level 3 = secondary consumers that eat primary consumers. Choices: - trophic level 5 - trophic level 4 - trophic level 2 - trophic level 3 A:
Ans: trophic level 3

Ques: Q: Runoff is likely to cause more what if the land is bare? Read this paragraph and choose the correct option from the provided answers: Runoff is likely to cause more erosion if the land is bare. Plants help hold the soil in place. The runoff water in Figure below is brown because it eroded soil from a bare, sloping field. Can you find evidence of erosion by runoff where you live? What should you look for?. Choices: - abrasion - sediment - weathering - erosion A:
Ans: erosion

Ques: Q: Electrons in the "outer shell" are also known as what kind of electrons? Read this paragraph and choose the correct option from the provided answers: Determine the total number of valence (outer shell) electrons. For cations, subtract one electron for each. Choices: - charged - intermediate - static - valence A:
Ans:
valence
