Which statement best explains the difference in the mouse populations on Island A and Island B at the end of the 20 years? More brown mice were in the half of the original population that was sent to Island B than in the group sent to Island A.

Conditions on Island B favored the individuals with brown fur, while both fur colors were evenly favored on Island A.

On Island A, the allele for gray fur was dominant, while on Island B, the allele for brown fur was dominant.

The recapturing of mice on Island A and Island B was done differently.

What evidence is there that convection occurs in earth’s troposphere?

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.
