Answer the following question given this paragraph: They will all blend together. The dyes will move through the water until an even distribution is achieved. The process of moving from areas of high amounts to areas of low amounts is called diffusion. Q: The process of moving from areas of high amounts to areas of low amounts is called what? Choices: - transfer - deposition - filtration - diffusion A:
diffusion

Answer the following question given this paragraph: Absorptive protists absorb food molecules across their cell membranes. This occurs by diffusion . These protists are important decomposers. Q: What protists absorb food molecules across their cell membranes? Choices: - dielectric - fibrous - solid - absorptive A:
absorptive

Answer the following question given this paragraph: Polar compounds, such as water, are compounds that have a partial negative charge on one side of each molecule and a partial positive charge on the other side. All polar compounds contain polar bonds (although not all compounds that contain polar bonds are polar. ) In a polar bond, two atoms share electrons unequally. One atom attracts the shared electrons more strongly, so it has a partial negative charge. The other atom attracts the shared electrons less strongly, so it is has a partial positive charge. In a water molecule, the oxygen atom attracts the shared electrons more strongly than the hydrogen atoms do. This explains why the oxygen side of the water molecule has a partial negative charge and the hydrogen side of the molecule has a partial positive charge. Q: All polar compounds contain what type of bonds? Choices: - balanced - strong - weak - polar A:
polar

Answer the following question given this paragraph: It may be logical to assume that the electrolysis of aqueous sodium chloride, called brine , would yield the same result through the same reactions as the process in molten NaCl. However, the reduction reaction that occurs at the cathode does not produce sodium metal because the water is reduced instead. This is because the reduction potential for water is only -0.83 V compared to -2.71 V for the reduction of sodium ions. This makes the reduction of water preferable because its reduction potential is less negative. Chlorine gas is still produced at the anode, just as in the electrolysis of molten NaCl. Q: Where is chlorine gas produced? Choices: - in the nucleus - carbon cycle - epidermis - at the anode A:
at the anode
