27. Which of the following statements are accurate?
A. Current scientific research supports that there is no link between autism and vaccination; that is vaccination has not been shown to contribute to development of autism.
B. The passage of antibodies from a mother's breast milk to the baby would be a good example of passive immunity.
C. You were not vaccinated against the measles virus (Measles morbillivirus). While at college you come in contact with a person suffering from measles. The person coughs on you and a few days later you have a cough, runny nose, and your throat feels sore. You also notice a red, blotchy skin rash. You recover from this illness. This would be a good example of natural active immunity.
D. Vaccines can promote a robust immune system but will cause the person to become sick as they are exposed to an infectious (highly virulent) pathogen.
E. none of the answers are correct
F. Vaccination typically does NOT produce life-long (memory cell) immunity to pathogens.

Read the following scenario to answer the following question. over the past 60 years, many amphibian species have experienced significant population declines, and some species have become extinct. scientists suspected that local human activities such as the destruction of wetlands, regional pollution, and deforestation were the main reasons for these losses. however, research over the past 20 years reveals significant amphibian population declines in protected areas of the world, such as nature preserves and parks. these global declines suggest widespread problems including increased ultraviolet radiation, acid rain, and disease. in switzerland, for example, 14 of the 20 native amphibian species are threatened with extinction. when most populations of a wide-ranging amphibian species are lost and the few remaining populations are widely separated, we expect to see that a. the founder effect becomes increasingly important b. microevolution no longer occurs c. gene flow between populations is reduced d. artificial selection becomes a greater factor in microevolution

Aresearcher designed an investigation to test what effect eating different types of food would have on blood insulin levels. she selected 10 male subjects who were all 25 years of age and in good health. the experiment took place over 3 days. at 8: 00 a.m. on each day, the subjects ate a meal consisting of only 1 type of food. they had their blood insulin levels measured after consuming the meal. on day 1 they ate a high fat diet, on day 2 they ate a high protein diet, and on day 3 they ate a high sugar diel what is the independent variable in this experiment? a the age of the subjects b the blood insulin level c the type of food consumed d the time of day the meal was consumed
