Cytochrome c is a molecule used in the electron transport chain of many organisms. Data regarding differences in the amino acid sequence of cytochrome c show that the sequence in a moth differs from a turtle by 15 about amino acids, while a moth differs from a human by about 30 amino acids. Therefore,

Which domain includes organisms with a well-organized nucleus?

Which piece of evidence did Darwin observe during his 5-year journey aboard the HMS Beagle?

There are two species of larkspur that have two different size flowers; Delphinium decorum has large, fully opened flowers and Delphinium nudicaule has small bud, like flowers.

Which type of isolating mechanism would this be?
