, she applies the theory to explain a variety of observations. For which of
these observations does the theory provide the most useful explanation?
A
Rock layers of the same age and containing matching fossils are found on separate continents
O
B. Seasonal variations in climate tend to increase with distance from the equator
C. Fossils generally are found in sedimentary rock, and not igneous or metamorphic rock
D. Mountainous regions tend to have cooler, wetter climates than low-lying lands

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? monarchs must threaten and attack birds, but not wasps. monarchs have a way of discouraging bird predation that does not involve hiding. monarchs’ wings are so colorful that most birds must find them difficult to eat. monarchs lay more eggs than other less conspicuous butterflies.
