Answer the following question given this paragraph: Penguins do not use their wings, known as flippers, to fly in the air. However, they do use them to move in the water. The theory of evolution suggests that penguins evolved to use their wings for a different purpose. A whale's pelvic bones, which were once attached to legs, are also vestigial structures. Whales are descended from land-dwelling ancestors that had legs. Q: What do you call structures like a whale's pelvic bones, which were once attached to legs, or wings that cannot be used for flight? Choices: - primitive - primordial - distinctive - vestigial A:

Question: Answer the following question given this paragraph: A metal is an element that is a good conductor of heat and electricity. Metals are also malleable, which means that they can be hammered into very thin sheets without breaking, and ductile, which means that they can be drawn into wires. When a fresh surface of any metal is exposed, it will be very shiny, because it reflects light well. This property is referred to as luster. All metals are solid at room temperature except mercury (Hg), which is a liquid. The melting points of different metals vary widely. Mercury has the lowest melting point of all pure metals (39C), and tungsten (W) has the highest (3422C). On the periodic table in Figure above , the metals are shaded blue and are located to the left of the bold stair-step line. About 80 percent of the elements are metals (see examples in Figure below ). Q: Which metal is not a solid even at room temperature? Choices: - iron - copper - aluminum - mercury A:
Answer: mercury
