A food web in a certain ecosystem consists of seals that feed on krill, which in turn feed on phytoplankton. Extensive krill fishing reduces the krill population rapidly. What would be observed in the ecosystem as an immediate effect of this? A) The seals would decrease in number and the phytoplankton would increase in number. B) The phytoplankton would decrease rapidly, because the seals would now feed exclusively on them. C) This would have no effect on the phytoplankton population as they just need sunlight to survive. D) The seals would increase in number because the lack of krill would mean less competition for food.

Mike was adopted, and his biological family history is unknown. although he is healthy, he would like some understanding of his genetic makeup, including potential health risks and genes that he could pass on to his children. mike has heard about commercial laboratories that can compare segments of your dna to those of people with common hereditary diseases in order to give you some idea of how susceptible you are to the diseases. the results of these types of tests are highly inconclusive. if mike's dna showed that he shares similarities in a segment of dna with people who have a given disease, his chances of developing that disease or passing it on to his children may be slightly elevated, but they are not 100 percent. these tests can cost more than $2,500 and are not covered by many insurance companies. do you think that mike should undergo the genetic tests? explain your answer. what are the potential pros and cons of having such tests done? describe how the availability of these genetic tests might affect the frequency of genetic diseases in individuals and populations.
