This apparent slowing down is due to the fact that, over time, the larger container begins to have enough iodine gas that some of it will be moving backwards towards the crucible. Large polar molecules cannot diffuse across a biological membrane B. The sugar dissolves and the mixture that is now in the cup is made up of a solute (the sugar) that is dissolved in the solvent (the water). Spontaneous activity releases energy, non-spontaneous activity (like moving something against its concentration gradient) requires energy. Obviously, the cell could not survive in such an environment. The sodium-potassium pump transports sodium out of and potassium into the cell in a repeating cycle of conformational (shape) changes. Increase C. Decrease D. It would depend on the nature and temperature of the coolant, 3. This can even be observed visually by the addition of different colored dyes to each of the liquids. Because of the increased capital investment required to produce new crop varieties using technology that was pioneered in more developed countries, there was an increase in wealth disparity in many farming communities in less developed countries.
