Answer the following question given this paragraph: Most ocean waves are caused by winds. A wave is the transfer of energy through matter. A wave that travels across miles of ocean is traveling energy, not water. Ocean waves transfer energy from wind to the water. The energy is transferred from one water molecule to the next. The energy of a wave may travel for thousands of miles. The water itself moves very little. The picture below shows how water molecules move when a wave goes by ( Figure below ). Once the wave starts, it doesn't need more wind to keep it going. Q: A wave is the transfer of energy through what else? Choices: - liquid - air - gas - matter A:
matter

Answer the following question given this paragraph: The chloroplasts contain a green pigment called chlorophyll, which captures the energy of sunlight for photosynthesis. Like plant cells, photosynthetic protists also have chloroplasts. Some bacteria also perform photosynthesis, but they do not have chloroplasts. Their photosynthetic pigments are located in the thylakoid membrane within the cell itself. Q: The chloroplasts contain a green pigment called what? Choices: - chloroplasm - sodium - melanin - chlorophyll A:
(Answer)
chlorophyll
Ques: Answer the following question given this paragraph: Aquatic plants are plants that live in water. Living in water has certain advantages for plants. One advantage is, well, the water. There's plenty of it and it's all around. Therefore, most aquatic plants do not need adaptations for absorbing, transporting, and conserving water. They can save energy and matter by not growing extensive root systems, vascular tissues, or thick cuticles on leaves. Support is also less of a problem because of the buoyancy of water. As a result, adaptations such as strong woody stems and deep anchoring roots are not necessary for most aquatic plants. Q: What kind of plants do not need adaptations for absorbing, transporting, and conserving water? Choices: - desert plants - normal plants - terrestrial plants - aquatic plants A:
Ans: aquatic plants
(Q).
Answer the following question given this paragraph: Polar Bears. Thick fur and a layer of blubber keep polar bears warm in their Arctic ecosystem. Why do you think their fur is white? Why might it be an adaptation in an Arctic biome?. Q: What type of ecosystem do polar bears live in? Choices: - tropical - oceanic - natural - arctic A:
(A).
arctic
Ques:Answer the following question given this paragraph: Chemical reactions vary widely in the speeds with which they occur. Some reactions occur very quickly. If a lighted match is brought in contact with lighter fluid or another flammable liquid, it erupts into flame instantly and burns fast. Other reactions occur very slowly. A container of milk in the refrigerator will be good to drink for weeks before it begins to turn sour. Millions of years were required for dead plants under Earth's surface to accumulate and eventually turn into fossil fuels such as coal and oil. Q: Exemplified by a lit match bursting into flame or the process that forms fossil fuels, chemical reactions vary greatly in terms of what? Choices: - duration - density - power - speed A:

Ans:speed
Question: Answer the following question given this paragraph: Q: What can damage animal tissues? Choices: - wind erosion - nervous stress - acid and water exposure - extreme pressure or temperature A:
Answer:
extreme pressure or temperature
