[Q]: Two scientists, Cathy and Mark, are working on a new project. They want to make a new polymer using two chemicals. Mark mixes the two chemicals together on the first day and after a week of waiting he has managed to create a new polymer. While he is happy about the result he feels a week is way to long. Cathy has an idea. She decides to try adding an enzyme to the chemical mixture, The mixture only takes seconds to form the new polymer and the enzyme she used is in tact floating on top of the now completed polymer. She decides to test even further and uses the left over enzyme on another batch of chemicals. The reaction occurs in seconds again and the same amount of enzyme is left floating on top of the polymer for her to use again in the next batch. Will using the enzyme in the chemical mixture increase or decrease the speed of the reaction?
****
[A]: increase

[Q]: Gary, a high school student, is supposed to be studying two different cells under a microscope during his biology class. Gary doesn't like biology class at all though and can't find the motivation to look at the cells in detail. In his homework where students are supposed to write what they observed, Gary simply wrote down the first thing he saw under the microscope which was that Cell A is larger than cell B. It won't get him a great grade, but Gary is hoping it will at least get him a pass on the assignment. Will Cell B have an easier or harder time transporting materials than cell A?
