Which is a natural sunscreen? Group of answer choices folate melanin keratin R.C. Lewontin found that human "races" have no taxonomic significance. In other words, race was not a valid biological category because: Group of answer choices All of the answers here are correct. a trait might cut across human populations in one way, but another trait cuts across human populations in another way. so-called racial traits are not concordant, and genes are largely inherited independently of one another. multiple biological traits do not lead to clear-cut racial classifications. What is a cause of rickets? Group of answer choices severe air pollution a lack of melanin a lack of vitamin D high UV exposure How did Franz Boas challenge the study of race? Group of answer choices He showed that U.S.-born children had different head shapes from their immigrant parents, demonstrating that races are not innately stable. He strongly supported the race concept. He showed that U.S.-born children had the same head shapes as their immigrant parents, proving that races are innately stable. He created racial categories based on living populations in the United States. Marco Polo was the first to employ the concept of race. Group of answer choices True False How did Johann Friedrich Blumenbach influence the study of race? Group of answer choices He showed that skull shape changed over time, suggesting that racial categories were not valid. He discovered the existence of three races not previously known. He used blood types and skin colors to demonstrate that races are not valid categories. He proposed five different races based on his study of several hundred skulls.
