Iguanas are living in a relatively dry habitat. genotypes and phenotypes for iguana feet can be seen above. the population of iguanas in the dry habitat contained individuals that did not have webbed feet. over three generations, the phenotype of the iguanas changed although the habitat did not. the ratio of webbed to non-webbed feet changed over time from 100% not webbed: 0% webbed to 50% not webbed: 50% webbed. elaborate on the reason for the change in phenotype within the population

Suppose you could go back in time to interview henri becquerel on the day he discovered radioactivity. from his perspective, write an account of the discovery.

Part a - which gene to compare? in this exercise, you will use the cytochrome c oxidase i (coi) gene to investigate relationships among salmon species. (this gene encodes a protein that functions in the mitochondrial electron transport chain.) you will compare the coi gene sequences from your salmon test samples to the standard sequences for each salmon species. in order for the coi gene to be useful for distinguishing among the different salmon species, which three statements must be true?
