A student uses a spectroscope and sees light with a wavelength of 650 nanometers (nm). Mark an X next to each statement he can make about the light. It is visible. It is ultraviolet. It is infrared. It transfers more energy than light with a wavelength of 700 nm. It has a higher frequency than light with a wavelength of 700 nm.

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
