Question asked by Filo student

In a temperate grassland system area of North America, vegetation has been destroyed by fire. What will happen to the net primary productivity and the local ecosystem when rains return in the next season?a. The grasses will grow back, but the herbivores that lived there will not return, as they wouldhave found new land to live on. Therefore, the net primary productivity would decrease.b. The grasses will not grow back, therefore the herbivores that lived there will not return. Thus,the net primary productivity would decrease.c. The grasses will grow back and the herbivores that lived there will return. The net primaryproductivity should also be similar to the previous season.d. The grasses will grow back and the herbivores that lived there will return. The net primaryproductivity would be less than the previous season.

The bacterium Neisseria meningitidis is often found in the throat of healthy people, but it sometimes penetrates the epithelium in the throat and invades the nervous system, causing meningitis. In North Africa, there are regular meningitis epidemics. These outbreaks almost always occur during the dry season. During the rainy season, although the bacteria are still present in the throat, they are far less likely to penetrate the epithelium and cause disease. Explain this observation based on what you learned about barriers to entry. 3. Innate and adaptive immunity are often discussed separately in textbooks as a matter of convenience. Yet, this separation is somewhat artificial. Provide two examples of how. 4. People who have had their spleen removed can usually live normal lives, but some, especially children, are placed on prophylactic antibiotics to prevent infection. If they must undergo surgery or even dental work, the dose of the antibiotic is often increased. Based on what you learned about the spleen, what do you think is the rationale for the use of prophylactic drugs? 5. In a famous experiment in immunology that demonstrated the concept of antigen presentation, scientists found that they could stimulate antibody production under laboratory conditions in one of the following situations. In which of the following scenarios do you think antibodies would most likely be produced? Explain your reasoning. Scenario A: Macrophages are exposed to antigen and are then mixed with B and T cells. Scenario B: B and T cells are exposed to antigen and are then mixed with macrophages. Scenario C: Macrophages are exposed to antigen and then mixed with B cells only. Scenario D: Macrophages are exposed to antigen and then mixed with T cells only. 6. Imagine that mice have their thymus removed at birth, before the immature T cells in the bone marrow that have migrated to the thymus can mature. What sorts of immune responses would these mice still be capable of? Which types of responses would no longer be possible? Explain this phenomenon based on what you have learned about the immune system. 7. Colds are caused by many different viruses. As we get older, we get fewer and fewer colds. Children get frequent colds, but older adults rarely get colds. Explain this phenomenon based on what you have learned about the immune system. A common metaphor used to describe the immune response is that of firefighters arriving to put out a fire. The fire might be extinguished, but the water used to put it out can also cause damage. Explain the biology behind this metaphor.
