Answer the following question given this paragraph: New mitochondria and chloroplasts are produced through a process similar to binary fission. Bacteria also reproduce through binary fission. Q: How do bacteria reproduce? Choices: - budding - nuclear fission - sexual reproduction - binary fission A:
binary fission

Answer the following question given this paragraph: Why do satellites stay in orbit? Why don't they crash into Earth due to the planet's gravity? Newton's law of universal gravitation describes what happens. Every object in the universe is attracted to every other object. Gravity makes an apple fall to the ground. Gravity also keeps you from floating away into the sky. Gravity holds the Moon in orbit around Earth. It keeps Earth in orbit around the Sun. Q: What keeps earth in orbit around the sun? Choices: - energy - motion - momentum - gravity A:
gravity

Answer the following question given this paragraph: The use of nuclear fusion for energy has several pros. Unlike nuclear fission, which involves dangerous radioisotopes, nuclear fusion involves hydrogen and helium. These elements are harmless. Hydrogen is also very plentiful. There is a huge amount of hydrogen in ocean water. The hydrogen in just a gallon of water could produce as much energy by nuclear fusion as burning 1,140 liters (300 gallons) of gasoline! The hydrogen in the oceans would generate enough energy to supply all the world's people for a very long time. Q: Unlike nuclear fission, which involves dangerous radioisotopes, nuclear fusion involves what two harmless elements? Choices: - magnesium and helium - hydrogen and oxygen - hydrogen and carbon - hydrogen and helium A:
hydrogen and helium

Answer the following question given this paragraph: The human body radiates heat in the range of infrared light. Night goggles work by 'seeing' the infrared light emitted by our bodies. Q: What piece of technology can you use to see infrared light? Choices: - light meters - microscope - telescope - night goggles A:
night goggles
