In the heterozygous brca2 mutation of the simulation, which of the following statements is true regarding the sanger sequencing method detection of the mutation? both the mutation and the wild-type base would be marked with the same ddntp at that position. the dye-labeled nucleotides only attach to mutated dna, so the mutation would be easily identified. you cannot tell where the mutation is by sanger sequencing if the individual is heterozygous for the mutation. another technique must be used. the mutation is not labeled with a ddntp and is therefore different from the wild-type sequence. in the sequencing reaction, the fragment identifying the mutation and the fragment identifying the wild-type base at that position would be the same length.

On a recent expedition to a remote region of northern canada, scientists uncovered skeletal remains from about 100,000 years ago. surprisingly, all the skeletal remains, which included many species from differing biological families and spanned about two thousand years, showed evidence of experiencing temperatures in excess of 1000 degrees fahrenheit (or 538 degrees celsius). which of the following, if true, best explains the apparent paradox between the cold environment and the evidence of the bones experiencing hot temperatures? (a) chemical changes that naturally occur during the process of decay in only one north canadian species produce the same evidence of the species' skeletons being exposed to hot temperatures as the expedition scientists found. (b) a little over 103,000 years ago, a large fire is known to have occurred in northern canada. (c) strong evidence exists that as early as 70,000 years ago, homo sapiens around the world relied heavily on fire to cook animals. (d) in the same expedition and in roughly the same layer of excavation, scientists found rudimentary wood cutting and hunting tools used by early humans.

What function does the limb sever in each animal? how are the limb bones of the four animals similar? based on these similarities what can be inferred about the evolution of the four animals.

Which characteristics are typical of a human population in the postindustrial stage?
