To work around this problem, the Ames test is done as follows:
A petri dish is seeded with salmonella colonies, moreover, in that petri dish a little chemical is added in the center. A culture medium is also added to the plate where agar is one of the ingredients and biotin and histidine have been mixed.
Only bacteria that show some kind of mutation will grow on these agar plates. This is because histidine has the function of allowing cell divisions necessary only for cases in which mutagenesis is necessary to occur.

electoral college vote is the amount of votes a state receives. so when you vote you vote for president a or president b.
if you vote for b and the majority of your state votes for a all of the electoral college votes go towards president a. each state has a certain amount of votes depending on the population of your state.
the pro are that you vote as a state
the cons are it doesnt really seem like democracy since its the"states" that are voting not the people. so there is 51 states and the president who wins certain states with the big numbers "electoral votes" will win the election.
its a way to simplify votes.
