Q: Why wouldn't a teakettle have an aluminum handle? Read this paragraph and choose the correct option from the provided answers: This teakettle is made of aluminum except for its handle, which is made of plastic. Aluminum is a good conductor of heat. It conducts heat from the flames on the range to the water inside the kettle, so the water heats quickly. Plastic, on the other hand, is not a good conductor of heat. It stays cool enough to touch even when the rest of the teakettle becomes very hot. Choices: - it absorbs light - it isn't washable - it is magnetic - it conducts heat A:
it conducts heat

Q: What is the atomic number? Read this paragraph and choose the correct option from the provided answers: In the modern periodic table, elements are organized by atomic number. The atomic number is the number of protons in an atom of an element. This number is unique for each element, so it seems like an obvious way to organize the elements. (Mendeleev used atomic mass instead of atomic number because protons had not yet been discovered when he made his table. ) In the modern table, atomic number increases from left to right across each period. It also increases from top to bottom within each group. How is this like Mendeleev's table?. Choices: - Number of electrons - Speed of electrons - Number of neutrons - number of protons A:
number of protons

Q: What do cells do in order to replace damaged or worn out cells? Read this paragraph and choose the correct option from the provided answers: Cells also divide in order to replace damaged or worn-out cells. Choices: - replicate - die - fold - divide A:
divide

Q: What is a continuous flow of electric charge called? Read this paragraph and choose the correct option from the provided answers: Electric current is a continuous flow of electric charge. It is measured in amperes (A). Direct current (DC) flows in just one direction. Alternating current (AC) keeps reversing direction. Choices: - powered current - microwave current - magnetism - electric current A:
electric current
