Because of base pairing in dna, the percentage of A adenine molecules in DNA is about equal to the percentage of guanine molecules B pyrimidines in dna is about equal to the percentage of purines C purines in dna is much greater than the percentage of pyrimidines D cytosine molecules in dna is much greater than the percentage of quanine molecules

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.
