Question 9

David Blehert and his research team captured 117 healthy bats to study in the laboratory and divided them into four groups. Group 1 was housed in an area free from Geomyces destructans. Group 2 was housed in an area that shared the same air as bats infected with WNS, but these bats did not have direct contact with the infected bats. Group 3 was housed in direct contact with other bats infected with WNS. Bats in group 4 were directly exposed to Geomyces destructans when it was applied to their wings. During the study period the bats were monitored for signs of WNS. In this experiment, the independent was ________ and the dependent variable was ________.

Accepted Answer

A)   the type of exposure to Geomyces destructans; whether the bats became sick with WNS
B)   whether the bats became sick with WNS; the type of exposure to Geomyces destructans
C)   whether the bats became sick with WNS; the number of bats included in the study
D)   the number of bats included in the study; the type of exposure to Geomyces destructans

Question 13

Is it possible for scientists to study events that happened to animals or plants that lived millions of years ago?

Accepted Answer

A)   Yes. Apply the laws of physics and nature that we know exist today to evaluate the evidence of past events. For example, observe modern animal behavior, structure, and function, and compare them to the structures of fossilized animals to deduce the function of the fossilized structures.
B)   No. The laws of physics that exist today are not the same laws of physics that existed in the past, so there is no way to compare plant or animal fossils to those of modern organisms and deduce the function of fossilized structures.
C)   Yes. Genetic manipulation of fossils allows scientists to directly test metabolic and behavioral characteristics of plants and animals from the past.
D)   No. There is no way to analyze plant or animal fossils that lived millions of years ago because the laws of nature that exist today have changed dramatically from the past.

B)   If snails live in moist habitats, then snails will be eaten more frequently by birds.
C)   If birds consume snails, then they will have a higher body mass index than birds that do not eat snails.
