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 german cockroaches, curved wing (cv) is recessive to normal wing (cv+). bill, who is raising cockroaches in his dorm room, finds that the frequency of the gene for curved wings in his cockroach population is 0.6. in his friend joe’s apartment, the frequency of the gene for curved wings is 0.2. one day joe visits bill in his dorm room, and several cockroaches jump out of joe’s hair and join the population in bill’s room. bill estimates that, now, 10% of the cockroaches in his dorm room are individual roaches that jumped out of joe’s hair. what is the new frequency of curved wings among cockroaches in bill’s room? 0.69 0.4 0.5 0.31 0.20
