On what day did the Paramecium aurelia population reach the carrying capacity of the environment? How do you know?

Day 8 because the days after the same number were repeated. (Hope that helps)

Idk

Ibelieve the answer is relative humidity  because it makes more sense that way. solar flares usually occur in space it doesn't affect the earth, well it could but it wont make a significant damage.  latitude is land it doesnt do anything. prevailing winds, i dont know the correct meaning for this but i doubt that affects the land so it has to be relative humidity.
