Select 3 of the following questions and compose a cited 200- 300 word;response. Each response must have a unique academic citation.;1. As discussed in the Biology and Society section, burning biomass to;produce electricity avoids many of the problems associated with;gathering, refining, transporting, and burning fossil fuels. Yet the use;of biomass as fuel is not without its own set of problems. What;challenges might arise from a large-scale conversion to biomass;energy? How do these challenges compare with those encountered;with fossil fuels? Which set of challenges do you think is more likely;to be overcome? Does one energy source have more benefits and;fewer costs than the others? Explain.;2. Many infertile couples turn to in vitro fertilization to try to have a baby.;In this technique, sperm and ova are collected and used to create;eight-cell embryos for implantation into a womans uterus. At the;eight-cell stage, one of the fetal cells can be removed without causing;harm to the developing fetus. Once removed, the cell can be;genetically tested. Some couples may know that a particular genetic;disease runs in their family. They might wish to avoid implanting any;embryos with the disease-causing genes. Do you think this is an;acceptable use of genetic testing? What if a couple wanted to use;genetic testing to select embryos for traits unrelated to disease, such;as freckles? Do you think that couples undergoing in vitro fertilization;should be allowed to perform whatever genetic tests they wish? Or do;you think that there should be limits on what tests can be performed?;How do you draw the line between genetic tests that are acceptable;and those that are not?;3. The human body has not changed much in the last 100,000 years, but;human culture has changed a great deal. As a result of our culture, we;change the environment at a rate far greater than the rate at which;many species, including our own, can evolve. What evidence of rapid;environmental change do you see regularly? What aspects of human;culture are responsible for these changes? Do you see any evidence of;a decrease in the rate of human-caused environmental changes?;4. Mammals have a four-chambered heart, with two ventricles and two;atria. So do birds, alligators, and crocodiles, but other living reptiles;have a three-chambered heart, with just one ventricle. Paleontologists;debate whether dinosaurs had a three-chambered or a four-chambered;heart. Long-necked sauropod dinosaurs could have had unusual;circulatory demands because their head may have been raised far;above their heart. The farther the head is above the heart, the greater;the systolic pressure needs to be for blood to reach the brain. For;example, the long-necked dinosaur Brachiosaurus may have carried its;head as much as 6 m (20 ft) above its heart. It is estimated that such;an anatomy demanded a systolic blood pressure of 500 mm of;mercury for blood to reach the brain! Some paleontologists consider;this evidence that dinosaurs had a four-chambered heart that supported;a dual circulatory system similar to that of birds and mammals, rather;than the three-chambered heart of most nonbird reptiles. Can you;explain why?;5. Design a laboratory experiment to measure the effect of water;temperature on the population growth of a certain phytoplankton;species from a pond.
