Q: What forms when water vapor condenses around particles in the air? Read this paragraph and choose the correct option from the provided answers: Clouds form when water vapor condenses around particles in the air. The particles are specks of matter, such as dust or smoke. Billions of these tiny water droplets come together to make up a cloud. If the air is very cold, ice crystals form instead of liquid water. Choices: - wind - storms - humididty - clouds A:
clouds

Q: Aside from light, incandescent light bulbs also give off what that wastes energy? Read this paragraph and choose the correct option from the provided answers: The classroom in Figure above has artificial light sources in addition to natural sunlight. There are fluorescent lights on the ceiling of the room. There are also projectors on the ceiling that are shining light on screens. In these and most other artificial light sources, electricity provides the energy and some type of light bulb converts the electrical energy to visible light. How a light bulb produces visible light varies by type of bulb, as you can see in Table below . Incandescent light bulbs, which produce light by incandescence, give off a lot of heat as well as light, so they waste energy. Other light bulbs produce light by luminescence, so they produce little if any heat. These light bulbs use energy more efficiently. Which types of light bulbs do you use?. Choices: - temperature - humidity - electricity - heat A:
(Answer)
heat

Ques: Q: Other than nitrogen, which nutrient most often limits marine production? Read this paragraph and choose the correct option from the provided answers: Choices: - potassium - zinc - calcium - phosphorus A:
Ans: phosphorus

(Q).
Q: What are genes that are close together on the same chromosome called? Read this paragraph and choose the correct option from the provided answers: Linked genes are genes that are close together on the same chromosome. Linked genes are inherited together. Choices: - mutated genes - infected genes - stored genes - linked genes A:
(A).
linked genes

Ques:Q: What moves sediments after they have formed? Read this paragraph and choose the correct option from the provided answers: Erosion moves sediments after they have formed. The sediments are transported away from the place where they form. There are several agents of erosion. Flowing water moves and deposits sediments. Water erodes far more material than any other erosional agent. Wind is important as an agent of erosion. This is especially true in arid climates. Ice, in glaciers, can erode enormous quantities of sediments. Gravity as a force of erosion pulls material downhill. Choices: - photosynthesis - migration - perspiration - erosion A:

Ans:erosion

Q: From where have the earliest ocean plants thought to have evolved? Read this paragraph and choose the correct option from the provided answers: The earliest plants are thought to have evolved in the ocean from a green alga ancestor. Plants were among the earliest organisms to leave the water and colonize land. The evolution of vascular tissues allowed plants to grow larger and thrive on land. The evolution of seeds and pollen allowed them to reproduce on land without moisture. Flowering plants evolved flowers with ovaries that formed fruits. They have been the most successful plants of all. Choices: - green pepinia ancestor - simple coral ancestor - simple alga ancestor - green alga ancestor A:
green alga ancestor
