Make a chart with e on the x-axis (1 – 10 gpa) and yield strength on the y-axis (10 – 100 mpa). select polypropylene (pp) and its various grades by applying a ‘tree’ stage selecting polymers – thermoplastics – pp (folder). label at least 10 records on the chart (from the bottom, middle, and top). insert the chart below, and then explain the trends you see. discuss the effects of 1) homopolymer versus copolymer, 2) ‘neat’ homopolymer versus additives, and 3) additives of particles versus fiber

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.
