Briefly describe a type of variation you observed within your most abundant OTU (here we are asking about differences that you noticed among individual specimens from the same "species"). How could you determine experimentally whether that variation is because of genetic differences, differences in the environment each organism experiences, or some combination of the two.

Which of the following types of stars is most likely to end up as a supernova? in graph a, the curve peaks at 800 nm, in the red section of the visible light spectrum. in graph b, the curve peaks at 550 nm, in the green section of the visible light spectrum. in graph c, the curve peaks at 450 nm, in the blue section of the visible light spectrum. in graph d, the curve peaks at 300 nm, in the violet section of the visible light spectrum. a b c d
