Answer the following question given this paragraph: CHAPTER SUMMARY 31.1 Nutritional Requirements of Plants Plants can absorb inorganic nutrients and water through their root system, and carbon dioxide from the environment. The combination of organic compounds, along with water, carbon dioxide, and sunlight, produce the energy that allows plants to grow. Inorganic compounds form the majority of the soil solution. Plants access water though the soil. Water is absorbed by the plant root, transports nutrients throughout the plant, and maintains the structure of the plant. Essential elements are indispensable elements for plant growth. They are divided into macronutrients and micronutrients. The macronutrients plants require are carbon, nitrogen, hydrogen, oxygen, phosphorus, potassium, calcium, magnesium, and sulfur. Important micronutrients include iron, manganese, boron, molybdenum, copper, zinc, chlorine, nickel, cobalt, silicon and sodium. Q: Plants can absorb inorganic nutrients and water through their root system, and what gas from the environment? Choices: - hydrogen dioxide - nitrogen dioxide - chemical dioxide - carbon dioxide A:
carbon dioxide
Answer the following question given this paragraph: Not really. Like all mammals, polar bears maintain a stable internal temperature. They do not need to stay warm by lying in the sun. This allows them to live in cold climates. Q: The ability to maintain a stable internal temperature, despite the climate, is exhibited by members of what animal group? Choices: - fish - parasites - reptiles - mammals A:
mammals
Q: Answer the following question given this paragraph: Motor vehicles account for almost half of fossil fuel use. Most vehicles run on gasoline, which comes from petroleum. Q: Motor vehicles account for almost half of the consumption of what? Choices: - hydrocarbon - greenhouse gases - electricity - fossil fuel A:
A: fossil fuel
Question: Answer the following question given this paragraph: Vivipary refers to the development and nourishment of an embryo within the mother's body but not inside an egg. Birth may be followed by a period of parental care of the offspring. This reproductive strategy occurs in almost all mammals including humans. Q: What refers to the development and nourishment of an embryo within the mother's body but not inside an egg? Choices: - birth - adolescence - ovulation - vivipary A:
Answer: vivipary

space efficiency
(Q).
Answer the following question given this paragraph: When a warm air mass runs into a cold air mass, it creates a warm front ( Figure below ). The warm air mass is moving faster than the cold air mass. The warm air mass then flows up over the cold air mass. As the warm air rises, it cools. This brings about clouds and sometimes light precipitation. Warm fronts move slowly and cover a wide area. After a warm front passes, the warm air mass behind it brings warmer temperatures. The warm air is also likely to be more humid. Q: What results when a warm air mass runs into a cold air mass? Choices: - cool front - dry front - rough front - warm front A:
(A).
warm front
