Problem: Students working on their thesis for graduate school decide that they will write about the differences between two identical plants, but they will infect one of the plants with a fungus. This fungus will create a mycorrhizal association between one of the plants and the fungus. After caring for the plants, the students have grown fond of them and given them names. They have named one of them Audrey and the other Baudrey. They flip a coin to decide which plant will be infected with the fungus, and fate has decided that Audrey will have the fungus grow on it. Baudrey will be left to grow naturally. Will Baudrey absorb minerals better or worse than Audrey?

A: worse

Problem: Mike is studying for his physics exam. He realizes that the best way to learn physics is to solve problems. To that end, he needs to to convert pressure of objects from one unit to another. In one problem, four scenarios are given for the same object, scenario A, scenario B, scenario C, and scenario D. In scenario A the pressure is given in Pascals. In scenario B the pressure is given in the atm. In scenario C the pressure is given in torr. Lastly, in scenario D the pressure is given in psi. In which scenario SI unit is used, scenario C or scenario D?

A: scenario C

Problem: Mike is studying the predator prey relationship. He is specifically studying three species, species A, species B, and species C. Species A is a predator; species B is the prey; and species C is a plant species that species B lives on. Mike now needs to figure out how the predator prey relationship balance the ecosystem. If species A population decrease, would it affect the ecosystem positively or negatively?

A:
negatively
