Detailed explanation-1: -Butterflies of the genus Colias live in the Rocky Mountains, where they experience a wide range of temperatures. Different variants of a particular glycolytic enzyme in the flight muscles are optimally active at different temperatures.
Detailed explanation-2: -The Clouded Sulphur butterfly (Colias philodice) is a medium-sized yellow North American butterfly which may be seen in the Adirondack Mountains in upstate New York throughout summer. It is also called the Common Sulfur.
Detailed explanation-3: -Which of the following statements best helps explain the reaction specificity of an enzyme? The shape and charge of the substrates are compatible with the active site of the enzyme.
Detailed explanation-4: -Which of the following best explains the cause of the phenotypic variation observed in the butterflies? There was differential gene expression of wing color and body size in response to the colors of light the caterpillars were exposed to.
