Apopulation of finches on an oceanic island varies at a particular gene locus. the current allele frequency is a 1 = 40%, a 2 = 60%, and there are 12,000 birds on the island. on the nearest continental mainland, the same species is monomorphic for allele a 1. if 3,000 birds migrate from the mainland to the island, by how much will the frequency of allele a 1 change on the island? group of answer choices 0.15 0.12 0.08 0.45 0.48

This is the diveristy of ecosystems natural communites and habits it is the variety of ways that species interact with each other and their environment

In 1959, doctors began using the powerful antibiotic methicillin to treat infections of staphylococcus aureus, but within two years, methicillin-resistant strains of s. aureus (mrsa) appeared. how did the resistant strains of s. aureus emerge? in 1959, doctors began using the powerful antibiotic methicillin to treat infections of staphylococcus aureus, but within two years, methicillin-resistant strains of s. aureus (mrsa) appeared. how did the resistant strains of s. aureus emerge? staphylococcus aureus bacteria that were able to synthesize cell walls using a protein that was not affected by methicillin survived the methicillin treatments and reproduced at higher rates than did other individuals. over time, these resistant individuals became increasingly common. in response to treatment of staphylococcus aureus infections with methicillin, some bacteria began to synthesize cell walls using a protein that was not affected by methicillin. these bacteria survived the methicillin treatments and reproduced at higher rates than did other individuals. over time, these resistant individuals became increasingly common. in response to treatment of staphylococcus aureus infections with methicillin, bacterial populations gradually began to synthesize cell walls using a protein that was not affected by methicillin.

Agenus is a taxonomic grouping that identifies a collection of species. when a scientist discovers a new species, how is this species assigned to a genus
