You measure the absorbance of a series of solutions that contained beet root segments. The first set of segments had been exposed to a 1% Detergent Solution for 45 minutes, and have a net average absorbance value of 0.476 at 470 nm. A second set of tubes was exposed to 1% Triton-X 100 for 45 min, and the net average absorbance is 0.669 at 470 nm. Which solution did more damage to the cells?

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
