Select only one answer for each question. Changing your mind 4) If you change an answer on the computer sheet, erase your original answer fully. Any question where you have chosen more than one answer will be marked incorrect. Circle the answer also on your exam sheet -- if you erase an answer on the computer sheet, indicate clearly on your exam sheet which answer you intend. 1. Dominant male elephant seals mate with multiple females. This mating system is best described as: a) polyandry b) polygyny c) polygamy d) polyploidy e) polymorphous 2. Conservation biologists apply ecological research to the design of reserves or protected areas. This is best described as: a) population ecology b) community ecology c) behavioural ecology d) population viability analysis e) landscape ecology 3. Of the following anatomical structures, which is homologous to the wing of a bat? a) dorsal fin of a shark b) tail of a kangaroo c) wing of a butterfly d) flipper of a fish e) arm of a human 4. Includes apicomplexans, oomycota, diplomonads and euglena: a) monerans b) protistans c) fungi d) animalia e) plantae 5. Red-winged and yellow-headed blackbirds both nest in marshes. Yellowheads are dominant to redwings when they are found together. Redwings will occupy the entire marsh if yellowheads are absent, but if yellowheads are present, they exclude redwings from the marsh center, and restrict redwings to the edge of the marsh. For red-winged blackbirds, the entire marsh would represent: a) habitat b) range c) population d) fundamental niche e) realized niche 6.

Brown-headed cowbirds exhibit a variety of adaptations to their brood parasitic lifestyle. They have short incubation times, they remove host eggs, and their nestlings exhibit exaggerated begging calls. Many host species have developed counteradaptations to avoid cowbird parasitism.
