Answer the following question given this paragraph: The Moon has no atmosphere. With no atmosphere, the Moon is not protected from extreme temperatures. The average surface temperature during the day is approximately 107C (225F). Daytime temperatures can reach as high as 123C (253F). At night, the average temperature drops to -153C (-243F). The lowest temperatures measured are as low as -233C (-397F). Q: What does the moon not have to protect it from extreme temperatures? Choices: - oceans - metals - oxygen - atmosphere A:
atmosphere
Answer the following question given this paragraph: Some elements have been known for centuries (gold, silver, iron, copper, among others) while others have been created in the lab only within the last several years. Most elements do not exist as such in nature. They are so reactive that they can be found only in combination with other materials. Q: What is the term for the process in which water vapor changes to tiny droplets of liquid water? Choices: - dispersion - vaporization - diffusion - condensation A:
condensation
Q: Answer the following question given this paragraph: When ancient plants underwent photosynthesis, they changed energy in sunlight to stored chemical energy in food. The plants used the food and so did the organisms that ate the plants. After the plants and other organisms died, their remains gradually changed to fossil fuels as they were covered and compressed by layers of sediments. Petroleum and natural gas formed from ocean organisms and are found together. Coal formed from giant tree ferns and other swamp plants. Q: During photosynthesis what organelle is used by plants to change sunlight into chemical energy? Choices: - mitochondria - golgi apparatus - ribosome - chloroplasts A:
A: chloroplasts

However, the eggs do not start to mature until she enters puberty. After menarche, one egg typically matures each month until a woman reaches middle adulthood. Q: When do the eggs in a female's ovaries start to mature? Choices: - maturity - adolescence - adulthood - puberty A:

Answer the following question given this paragraph: You can see how Mendeleev organized the elements in Figure below . From left to right across each row, elements are arranged by increasing atomic mass. Mendeleev discovered that if he placed eight elements in each row and then continued on to the next row, the columns of the table would contain elements with similar properties. He called the columns groups . They are sometimes called families, because elements within a group are similar but not identical to one another, like people in a family. Q: In the periodic table, elements are arranged from left to right according to what property? Choices: - metallic mass - real mass - major mass - atomic mass A:
**Answer**
atomic mass

Answer the following question given this paragraph: Solar energy is used to heat homes and water, and to make electricity. Scientists and engineers have many ways to get energy from the Sun ( Figure above ). One is by using solar cells. Solar cells are devices that turn sunlight directly into electricity. Lots of solar cells make up an individual solar panel. You may have seen solar panels on roof tops. The Sun's heat can also be trapped in your home by using south facing windows and good insulation. Q: The sun's heat can also be trapped in your home by using south facing windows and good what? Choices: - floors - vegetation - curtains - insulation A:
(Answer)
insulation
