Problem: 1. Select the scenarios that describe stabilizing selection. Select the TWO answers that are correct. A. The larger the adult male bullfrog is, the more successful he is at attracting mates B. The longest lizard tails look like snakes and keep predators away. C. Cats with short tails do not balance well, and cats with long tails are clumsy. D. Water Insects with either small bodies or large bodies have the longest lifespan. E. In chickens, eggs of intermediate weight show the highest rate of hatching. 2. Select the scenarios that describe diversifying selection. Select the TWO answers that are correct. A. In a species of butterfly, both the white- and black-winged adults are toxic to predators, but the gray-winged butterflies are not. B. In a patchy underwater habitat, light-colored oysters blend into the rocks and dark-colored oysters blend into the shadows. C. The larger female insect lays more eggs, but the smaller female insect lives longer D. As the tree bark darkened during industrial times, the bodies of the butterflies in the forest areas also darkened. E. In robins, laying too few eggs lowers viability of young and too many eggs leads to inability to provide sufficienty for young
