Green lizards were observed in the region in the image. changes in the geography of the region caused the formation of a stream, which divided the region into two halves. the left half developed a dark green environment, and the right half a comparatively lighter green environment. as a result, two geographically isolated populations, dark and light green lizards inhabited either side of the stream. the region on the right has more light green lizards as a result of . the new species will develop by way of . 1. a. natural seletion b. postzygotic isolation c. harmful mutation 2. a. sympatric speciation b. allopatric speciation c. convergent evolution

In the presence of oxygen, glycolysis is followed a. the krebs cycle b. lactic acid fermentation c. alcoholic fermentation d. photosynthesis

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.
