Question 6

Salmon live in both fresh water and salt water during their lives. They are born in in fresh water but migrate out to marine waters for most of their life. Eventually, they return to the place they were born in fresh water to spawn. Changing between fresh water and salt water affects the balance of water in their body. Salmon have an internalcontrol system called osmoregulationthatrestores the balance by negative feedback. This is an example of which characteristic of life?

Accepted Answer

A)   adaptation
B)   reproduction and development
C)   response to the environment
D)   energy transformation
E)   maintaining homeostasisF) B) and E)
G) A) and B)

Question 7

Male amphibians, including frogs and toads, have been plagued by feminization, deformity, behavioral abnormalities and sterility. Biologists from the University of Floridainvestigated whether reproductive problems among populations of cane toads ( Bufo marinus)  arecaused by poisons from chemicals associated with agriculture. The biologists collected local adult cane toadsfrom more than 20 different locations. Toads were collected from areas close to agriculture, both large-scale and small-scale farms, as well as from suburbs that are nonagricultural areas.Data collected by the biologists suggested a strong correlation between feminization of male toads and agricultural chemicals. Is it accurate to state that the scientists had supported their theory that agricultural chemicals cause deformities?

Accepted Answer

A)   yes, the data collected during the study strongly supports their theory
B)   no, the data did not show a link between the feminization of male toads and agricultural chemicals
C)   no, the scientists were testing a hypothesis which is not the same things as a theory
D)   yes, this was a controlled study.
E)   no, this was a controlled study.F) None of the above
G) A) and C)

Question 8

Scientists were studying temperature selection among pregnant big brown bats. What would the test group be in this experiment?

Accepted Answer

A)   pregnant bats
B)   female bats that were not pregnant
C)   male bats
D)   juvenile male bats
E)   juvenile female batsF) None of the above
G) A) and E)

Question 9

Which of the following is a true statement about extinction?

Accepted Answer

A)   Many extinctions are associated with climate change.
B)   It is estimated that presently we are losing hundreds of species every year due to human activities.
C)   It is estimated that as much as 38% of all species, including most primates, birds, and amphibians, may be in danger of extinction before the end of the century.
D)   Extinction is the death of a species or a larger taxonomic group.
E)   All of the statements about extinctionare true.F) A) and E)
G) A) and B)

Question 14

Eli keeps a worm bin in his basement because the worms need cooler temperatures to survive. He feeds them about one pound of kitchen scraps each week. One summer the temperatures rose above the optimal temperature for the red worms (~ 85°F)  and many in his colony died. However, those that survive continued to reproduce and within six months his colony was thriving again. The following summer, unusually warm temperatures once again resulted in the basement temperatures rising above 85°F. Surprisingly, Eli noticed that only a small portion of the worm colony died. What is the best explanation for this?

Accepted Answer

A)   After the first summer, a new species of worm evolved.
B)   The worms sensed that the temperature was going to be hot in the future and adapted.
C)   The worms learned how to tolerate higher temperatures.
D)   The worms that survived the first summer had a higher heat tolerance and passed this trait on to their offspring.
E)   Temperature and worm survival are not related.F) A) and E)
G) None of the above
