Answer the following question given this paragraph: Viruses are classified on the basis of several traits. For example, they may be classified by capsid shape, presence or absence of an envelope, and type of nucleic acid. Most systems of classifying viruses identify at least 20 virus families. Table below shows four examples of virus families and their traits. Have any of these viruses made you sick?. Q: Lampreys use their sucker to feed on what part of other fish species? Choices: - heart - brain - liver - blood A:
blood
Answer the following question given this paragraph: Q: What is generated when a heart ventricle contracts? Choices: - vein pressure - blood force - artery pressure - blood pressure A:
blood pressure
Q: 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:
A: nuclear fission
Question: Answer the following question given this paragraph: Summary Real crystals contain large numbers of defects. Defects may affect only a single point in the lattice (a point defect), a row of lattice points (a line defect), or a plane of atoms (a plane defect). A point defect can be an atom missing from a site in the crystal (a vacancy) or an impurity atom that occupies. Q: A point defect can be an atom missing from a site in the crystal known as a what? Choices: - void - deficiency - vacuum - vacancy A:
Answer: vacancy

Answer the following question given this paragraph: The coordination sphere consists of the central metal ion or atom plus its attached ligands. Brackets in a formula enclose the coordination sphere; species outside the brackets are not part of the coordination sphere. The coordination number of the central metal ion or atom is the number of donor atoms bonded to it. The coordination number for the silver ion in [Ag(NH3)2]+ is two (Figure 19.14). For the copper(II) ion in [CuCl4]2, the coordination number is four, whereas for the cobalt(II) ion in [Co(H2O)6]2+ the coordination number is six. Each of these ligands is monodentate, from the Greek for "one toothed," meaning that they connect with the central metal through only one atom. In this case, the number of ligands and the coordination number are equal. Q: The coordination sphere consists of the central metal ion or atom plus its attached what? Choices: - subunits - strands - molecules - ligands A:
(Answer)
ligands
