The graph below shows the change in blood glucose level during prolonged exercise. Which of the following statements explains the change in blood glucose level shown in the graph? Change in Blood Glucose Level 6.0 5.5+ 5.0+ Blood Glucose Concentration (mm) 45+ 40+ 3.5+ 3.0 + 0 30 20 Exercise Time (min) 60 O Glucose diffused from muscle cells into the bloodstream. hy Glucose was broken down to produce ATP for energy. Proteins combined with glucose to produce ADP for energy. Polysaccharides were made from glucose in metabolic pathways.​

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.
