When biologists study natural selection they are looking for changes in genotype or allele frequencies across generations in the real world. You will see this in more detail in lab next week. However, based on the thinking you have just done about plant growth, density, and neighbors, which experimental treatment(s) is (are) most likely to give you information about relative fitness of the two morphs that would apply to nature

Astudent sees several ants walking up a wall following the exact same trail that an ant took earlier. she wants to apply the scientific method to determine how the ants detected the trail. which of these steps would come first in her application of the scientific method? perform an experiment by cleaning the scent away from part of the trail. draw a conclusion that the ants follow a scent trail. make a prediction about what the ants will do after she cleans away part of the trail. hypothesize that the ants are following a scent trail that the first ant left.
