Answer the following question given this paragraph: The four planets closest to the SunMercury, Venus, Earth, and Marsare the inner planets or terrestrial planets ( Figure below ). They are similar to Earth. All are solid, dense, and rocky. None of the inner planets has rings. Compared to the outer planets, the inner planets are small. They have shorter orbits around the Sun and they spin more slowly. Venus spins backward and spins the slowest of all the planets. Q: Where are the terrestrial planets located, in relation to the sun? Choices: - farthest - To the left - To the right - closest A:
closest

Answer the following question given this paragraph: Lymphocytes are the key cells in the immune response. They are leukocytes that become activated by a particular antigen. There are two major type of lymphocytes: B cells and T cells. Q: What are the key cells in the immune response? Choices: - keratinocytes - erythrocytes - leukocytes - lymphocytes A:
lymphocytes

Answer the following question given this paragraph: These values suggest that water should be oxidized at the anode because a smaller potential would be neededusing reaction (ii) for the oxidation would give a less-negative cell potential. When the experiment is run, it turns out chlorine, not oxygen, is produced at the anode. The unexpected process is so common in electrochemistry that it has been given the name overpotential. The overpotential is the difference between the theoretical cell voltage and the actual voltage that is necessary to cause electrolysis. It turns out that the overpotential for oxygen is rather high and effectively makes the reduction potential more positive. As a result, under normal conditions, chlorine gas is what actually forms at the anode. Now consider the cathode. Three reductions could occur:. Q: What are the two metals within a battery called? Choices: - sheath and a cathode - anode and sheath - anode and diode - anode and a cathode A:
anode and a cathode
