A human takes a deep breath in. At first, outside the humans lung cells, there are many exygen molecules. After diffusion occurs, how will the inside of the lung cells look compared to their outside environment in terms of oxygen molecules?
a) The oxygen molecules concentration would be lower in the lung cells and higher in the outside environment.
b) The oxygen molecule concentration would be the same, or equal, both inside the lung cells and in the outside environment.
c) The oxygen molecule concentration would continue to be higher in the lung cells and lower in the outside environment.
d) There is no way to determine the oxygen molecule concentration because every humans lungs vary.

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.
