A population of finches on an oceanic island varies at a particular gene locus. The current allele frequency is A1 = 40%, A2 = 60%, and there are 12,000 birds on the island. On the nearest continental mainland, the same species is monomorphic for allele A1. If 3,000 birds migrate from the mainland to the island, by how much will the frequency of allele A1 change on the island?

Marco is studying a type of mold that grows at a fast rate. he created the function f(x) = 345(1.30)x to model the number of mold spores per week. what does the 1.30 represent? how many mold spores are there after 4 weeks? round your answer to the nearest whole number. 1.30 represents the number of mold spores marco had at the beginning of the study; 985 mold spores 1.30 represents the number of mold spores grown in a given week; 448 mold spores 1.30 represents the 30% rate of weekly growth; 345 mold spores 1.30 represents the 30% rate of weekly growth; 985 mold spores
