(05.02 MC)Monarch butterflies have brightly colored orange wings with black patterns on them, making them easily visible to birds that eat butterflies and moths, yet birds rarely eat the monarchs. Likewise, the monarch caterpillars are brightly striped yellow and white and black, and they also are rarely eaten by birds, although some wasps will attack them and feed them to their young. What can be inferred from these observations?

(05.02 MC)The following observations have been made about moose living in the northeastern forests of the United States. Male moose grow very broad antlers each year and lose them after the mating season in autumn. Large, heavy antlers can make escaping predators in a forest difficult if the trees grow closely together or if the underbrush is thick. Female moose do not develop antlers. Female moose raise their calves alone without the assistance of males. What is the most likely inference that can be drawn from these observations?

(05.02 HC)Guppies living in a stream have a variety of spot patterns, some of which provide good camouflage against the stones in the streambed and others of which make them stand out against the background, allowing potential mates to see them more easily. If a predator that hunted by sight were introduced to the stream, what would be the most likely long-term consequence for the guppy population?
