Atherosclerosis is a disease that obstructs blood flow and, therefore, oxygen supply to target organs. A major component of atherosclerosis is the excessive reproduction of smooth
muscle cells of the blood vessels. Certain drugs may have the potential to reverse or prevent
the unregulated reproduction of the diseased blood vessel cells. Which of these processes is
the most likely target of these drugs?

Ry was studying two populations of the same species of lizards. one population lived on an island and the other lived on the mainland. both populations were affected by a hurricane that hit the island and the mainland with equal force. a year later, henry was testing the gene frequency and saw a decrease in genetic variation in the island species, but not in the mainland species. which best describes a conclusion he might have reached? gene flow greatly affects small populations, but large populations can recover. genetic drift greatly affects small populations, but large populations can recover. gene flow greatly affects large populations, but small populations can recover. genetic drift greatly affects large populations, but small populations can recover.

Why can cancer in the lymph nodes (lymphoma) be particularly dangerous? a. the lymph node's ability to produce cancer-fighting lymphocytes would be compromised. b. the lymph node's ability to produce cancer-fighting lymph would be compromised. c. the lymph nodes produce lymph, which nourishes growing cancer cells. d. the lymph nodes produce chyle, which nourishes growing cancer cells.
