Answer the following question given this paragraph: The weight of an object is the force pulling the object downward. On Earth, this would be the gravitational force of the Earth on the object. On the moon, this would be the gravitational force of the moon on the object. The gravitational force of the moon is one-sixth the magnitude of the gravitational force of the Earth; the weight of the moon rock on the moon will be one-sixth the weight of the moon rock on the Earth's surface. Weight is measured in force unitsnewtonsby a calibrated spring scale as shown here. Q: What is the force pulling an object downward called? Choices: - momentum - density - magnetism - weight A:
weight
Answer the following question given this paragraph: Severe thunderstorms have a lot of energy and strong winds. This allows them to produce tornadoes. A tornado is a funnel-shaped cloud of whirling high winds. You can see a tornado in Figure below . The funnel moves along the ground, destroying everything in its path. As it moves it loses energy. Before this happens it may have gone up to 25 kilometers (16 miles). Fortunately, tornadoes are narrow. They may be only 150 meters (500 feet) wide. Q: What is a funnel-shaped cloud of whirling high winds known as? Choices: - volcano - tsunami - hurricane - tornado A:
tornado
Q: Answer the following question given this paragraph: Insects eat in many different ways and they eat a huge range of foods. Around half are plant-eaters, feeding on leaves, roots, seeds, nectar, or wood. Aphids and leafhoppers suck up the sap from plants. Praying mantises are predators, hunting other small creatures, including insects like moths, caterpillars, flies, beetles, and spiders. Insects like mosquitoes and aphids have special mouthparts that help them pierce and suck. Others, like assassin bugs ( Figure below ) and certain species of female mosquitoes, eat other insects. Fleas and lice are parasites, eating the flesh or blood of larger animals without killing them. Q: What are the insects that suck up the sap from plants? Choices: - plagues and leafhoppers - butterflies and leafhoppers - roaches and leafhoppers - aphids and leafhoppers A:
A: aphids and leafhoppers
Question: Answer the following question given this paragraph: Nuclear fission is the splitting of the nucleus of an atom into two smaller nuclei. This type of reaction releases a great deal of energy from a very small amount of matter. For example, nuclear fission of a tiny pellet of uranium-235, like the one pictured in Figure below , can release as much energy as burning 1,000 kilograms of coal!. Q: What do you call the splitting of the nucleus of an atom into two smaller nuclei? Choices: - critical fission - nuclear fusion - cell division - nuclear fission A:
Answer: nuclear fission

Answer the following question given this paragraph: This bottle of water models the semicircular canals in your ears. When you tip the bottle, the water moves up or down the sides of the bottle; when you tip your head, the liquid inside the semicircular canals moves up and down the sides of the canals. Tiny hair cells lining the canals sense the movement of liquid and send messages to the brain. Q: What senses the movement of liquid in ear canals? Choices: - Ear Drum - Brain Cells - muscle cells - hair cells A:
**Answer**
hair cells

Answer the following question given this paragraph: The most useful quantity for counting particles is the mole. So if each coefficient is multiplied by a mole, the balanced chemical equation tells us that 1 mole of nitrogen reacts with 3 moles of hydrogen to produce 2 moles of ammonia. This is the conventional way to interpret any balanced chemical equation. Q: What is the most useful quantity for counting particles? Choices: - the coefficient - the periodic table - the vector - the mole A:
**Answer**
the mole
