Answer the following question given this paragraph: Steel is an example of an alloy. An alloy is a mixture of a metal with one or more other elements. The other elements may be metals, nonmetals, or both. An alloy is a solid solution. It is formed by melting a metal and dissolving the other elements in it. The molten solution is then allowed to cool and harden. Several other examples of alloys and their uses are shown in Figure below . You can learn about an amazing alloy called memory wire at the URL below. If you have braces on your teeth, you may even have this alloy in your mouth!. Q: A mixture of a metal with one or more other elements is called? Choices: - a carbon - a hydrogen - a cobalt - an alloy A:
an alloy

Answer the following question given this paragraph: The Noble Gases The noble gases are helium, neon, argon, krypton, xenon, and radon. Because the noble gases are composed of only single atoms, they are monatomic. At room temperature and pressure, they are unreactive gases. Because of their lack of reactivity, for many years they were called inert gases or rare gases. However, the first chemical compounds containing the noble gases were prepared in 1962. Although the noble gases are relatively minor constituents of the atmosphere, natural gas contains substantial amounts of helium. Because of its low reactivity, argon is often used as an unreactive (inert) atmosphere for welding and in light bulbs. The red light emitted by neon in a gas discharge tube is used in neon lights. Q: Noble gases are monatomic because they only contain one of what? Choices: - ions - molecules - charges - atoms A:
(A).
atoms
Ques:Answer the following question given this paragraph: Diffusion is the movement of molecules from an area of high concentration to an area of low concentration. Q: What is the term for the movement of molecules from an area of high concentration to an area of low concentration? Choices: - concentration - Osmosis - passive transport - diffusion A:

Ans:diffusion
Answer the following question given this paragraph: Unlike that of the Hexapoda, the head and thorax of most crustaceans is fused to form a cephalothorax (Figure 28.40), which is covered by a plate called the carapace, thus producing a body structure of two tagma. Crustaceans have a chitinous exoskeleton that is shed by molting whenever the animal increases in size. The exoskeletons of many species are also infused with calcium carbonate, which makes them even stronger than in other arthropods. Crustaceans have an open circulatory system where blood is pumped into the hemocoel by the dorsally located heart. Hemocyanin and hemoglobin are the respiratory pigments present in these animals. Q: In most crustaceans, what two structures fuse to form a cephalothorax? Choices: - foot and toes - body and shoulders - wing and legs - head and thorax A:
head and thorax
