Question

A May 6, 2014 article about Chernobyl in the Science Times quotes Dr. Mousseau, "For these birds, chronic exposure to radiation appears to be a kind of "unnatural" selection driving evolutionary change. How would you interpret this? a. most birds will go extinct due to the cancers caused by the radiation b. the birds that detected the radiation migrated elsewhere, and the allele frequencies have change c. radiation will mutate food sources and cause them to be more nutritious d. most birds have become deformed, which will be evident in future generations. e. Mutations may actually help some birds to be more adaptive and outcompete other birds in their environment In another May 6^th article about the 1918 flu pandemic, it was pointed out that that flu seemed to target people in their twenties, in contrast to the flu today, that tends to target children and the elderly. When this strain was injected into monkeys, they had a severe allergic reaction. From this, it has been that the young people: a. that had the strongest immune system were at the greatest risk b. that people are the most closely related to the monkeys used in the experiment c. that the people with the weakest immune systems were ate the greatest risk d. that this virus was related to the bird flu e. a and b

Explanation / Answer

Answer

1) Option e is the right answer " mutation may actually help some birds to be more adaptive and outcompete other birds in their environment". This is obvious because a mutation in the bird may give them a competitive advantage in a particular environment, therefore, birds with mutation outcompete other in that environment.

2) option a is the right answer because with that observation we can conclude that stronger immune system will give a more allergic reaction, therefore, stronger flu symptoms.
