He arm or forelimb of humans, horses, goats, and mice all exhibit the same three bone structures: humerus, ulna, and radius. which statement best explains this common skeletal structure? a) the limb bones are similar across these species because they share a common ancestor. b) the limb bones are the same across these species because all of them move in a similar way. c) the limbs are similar because of the recurring patterns of genetic mutation that are common in the animal kingdom. d) the limbs are structurally similar due to convergent evolution--different organisms evolving to become structurally similar.

Mutations associated with albinism affect proteins involved in synthesis

Which type of scientific statement is defined as a hypothesis or group of hypotheses that can be accepted as true based on the repeated experimentation with similar results

Awoman whose sister tested positive for a specific mutation in the brca1 gene, which increases the risk for breast and ovarian cancer, is found not to have that mutation but does have a mutation of unknown significance near the known mutation site. how should this woman be counseled? select one: a. she should be informed that her risk for breast cancer is greater than the general population but not as great as her sister’s risk. b. she should be informed that because she does not have the mutation, her risk for breast cancer is not greater than that of the general population. c. she should be informed of her gene mutation status and be presented with all the available prophylaxis options and reconstruction options. d. she should be informed that she does not have the specific mutation but that because another mutation is present she should be vigilant about screening
