16. Six pairs of bald eagles were released into the wild in Indiana. Four of the pairs of birds successfully nested and raised young. Two of the pairs nested near an industrial complex that released waste products (PCBs) into a nearby lake. These birds laid eggs, but the embryos failed to develop.
Which of the following is the LEAST likely reason for the failure of the embryos to develop?
A. Mutations in the embryos halted their development.B. The adult birds failed to exhibit proper nesting behavior and did not care for the eggs.C. The contaminated lake water that the birds consumed affected the development of their young.D. The sperm of the males were affected by the PCBs in such a way that they were unable to fertilize the eggs.E. Indiana is not a good location for bald eagles to mate and reproduce.
17. Six pairs of bald eagles were released into the wild in Indiana. Four of the pairs of birds successfully nested and raised young. Two of the pairs nested near an industrial complex that released waste products (PCBs) into a nearby lake. These birds laid eggs, but the embryos failed to develop.
The eggshells of the embryos that failed to develop were tested and were found to contain more PCBs than the nearby plants and insects. This is due to
A. biomagnificationB. increased levels of PCBs in the lakeC. the resistance of the insects to PCBsD. failure of the plants to take up PCBsE. absorption of PCBs from the nesting site into the eggshell

19. Questions below wrefers to the following data obtained for a rabbit population over a period of several years.
Assuming unlimited resources, what would be the approximate expected rabbit population in Year 5 ?
A. 5000B. 1000C. 500D. 300E. 100
20. Questions below wrefers to the following data obtained for a rabbit population over a period of several years.
