Q: Dna replication, chromosome segregation, and the separation into two daughter cells are steps in what process? Read this paragraph and choose the correct option from the provided answers: Binary fission can be described as a series of steps, although it is actually a continuous process. The steps are described below and also illustrated in Figure below . They include DNA replication, chromosome segregation, and finally the separation into two daughter cells. Choices: - reproductive fission - nuclear fission - multiple fission - binary fission A:
binary fission

Q: Where is chlorine gas produced? Read this paragraph and choose the correct option from the provided answers: 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. Choices: - in the nucleus - carbon cycle - epidermis - at the anode A:
at the anode

Q: What is the process of making atp without oxygen called? Read this paragraph and choose the correct option from the provided answers: An important way of making ATP without oxygen is called fermentation . It involves glycolysis, but not the other two stages of aerobic respiration. Many bacteria and yeasts carry out fermentation. People use these organisms to make yogurt, bread, wine, and biofuels. Human muscle cells also use fermentation. This occurs when muscle cells cannot get oxygen fast enough to meet their energy needs through aerobic respiration. Choices: - condensation - photosynthesis - Cell Division - fermentation A:
fermentation

Q: In what form is the heat absorbed when you heat ice and it reaches a temperature of 0 c? Read this paragraph and choose the correct option from the provided answers: The heating curve shown is for water but other substances have similarly shaped heating curves. Suppose you begin with solid water (ice) at -30C and add heat at a constant rate. The heat you add in the beginning will be absorbed as kinetic energy and the temperature of the solid will increase. When you reach a temperature of 0C (the melting point for water), the heat you add is no longer absorbed as kinetic energy. Instead, the added heat is absorbed as potential energy and the particles separate from each other. During the flat part of the curve labeled "melting", heat is being added constantly but the temperature does not increase. At the left edge of this flat line, the water is solid; by the time enough heat has been added to get to the right edge, the water is liquid, but maintains the same temperature. Once all the water is in the liquid form, the added heat will once again be absorbed as kinetic energy and the temperature will increase again. During the time labeled "water being heated as a liquid", all the added heat is absorbed as kinetic energy. Choices: - geothermal energy - mechanical energy - radiation energy - potential energy A:
potential energy
