What is the link between colored pigment molecules and other organic molecules?
Many traits of organisms, such as body form and color, are controlled by specific proteins, in turn controlled by the DNA genetic sequence of nucleotides. The genetic control of color, as in aphids, does not usually shift during the life of an organism. Researchers found that some specific aphid populations shift from an original red coloration to a green coloration. Genetics could be a factor, if some programmed shift could be identified. Environmental conditions of the living and nonliving habitat could be a factor. Either way, the chemistry and observed changes of pigment molecules in the aphids can be studied with the scientific method. A. All of the answer choices are correct. B. In the case of the aphids, the pigment molecules of bacteria are genetically passed on to the DNA of infected aphids. C. The DNA molecule genetic sequence regulates protein molecule function, which can change pigment structure that affects color. D. Pigment molecules are made up of all four of the other organic molecule groups. E. This one group of aphids can easily alter the pigment molecule structure by modifying its DNA nucleotide sequence and building new proteins.

Being born with extra fingers on a hand is called polydactyly. This is more common in some populations in North America than others due to ________.
A. random mating with other populations in North America B. natural selection in favor of extra fingers in these populations C. a founder effect because their ancestors from Europe carried the alleles D. migration of people with multiple fingers out of the population E. an increase in mutation rate in these populations
