Answer:
Immunity to Small Pox
Explanation:
Over the years, Europeans had built up an immunity to smallpox because many had contracted the disease and still survived. As the population grew children were born with some immunity to the disease. When the Europeans arrived in the Americas, and smallpox spread around the native peoples, the Europeans did not contract the disease because they were immune. However, since the natives were not immune, they slowly died of due just to the disease as well as some parts of the war between the europeans.
Answer:
Water will move into the beaker.
Explanation:
Only water can move between the bags. The water and the NaCl naturally want to reach equilibrium, so since the side with 80% NaCl is more concentrated, the water will move there to make it less concentrated. Both inside the back and in the beaker will reach 75% NaCl.
Comparing DNA
Darwin could compare only the anatomy and embryos of living things. Today, scientists can compare their DNA. Similar DNA sequences are the strongest evidence for evolution from a common ancestor. Look at the diagram in Figure 9.3
