A fertilized egg that is a genetically male bearded dragon can develop into a female dragon if the air temperature is high enough. What is the likely cause of this phenomenon?A.Bearded dragons' development is unaffected by their DNA.B.Bearded dragons prefer higher air temperatures.C.Temperature affects the way cells differentiate.D.Cellular division is slowed down by higher temperatures.SUBMITarrow_backPREVIOUS

How do changes in temperature affect the rate of a reaction?A.Increasing temperature increases the reaction rate because the particles move faster and collide more often.B.Increasing temperature decreases the reaction rate because the particles break down into nonreactive substances.C.Decreasing temperature increases the reaction rate because the particles are more likely to react when they collide.D.Changing temperature does not affect the rate of a reaction because it does not change the activation energy.

One reason scientists study turtles is because they live in wildly various environments, and, as a result, could have morphological structures that reflect different adaptations. Scientists have theorized that the main determiner of variance in the shells of turtles is habitat difference. In a study, Fanrong Xiao and his colleagues examined this theory by finding prevailing trends across multiple species of turtle.Which finding from Xiao and his colleagues’ study, if true, would most directly challenge the assumption in the underlined sentence?Male and female turtles in the same environment had differently sloped and sized shells.eliminateTurtles living in freshwater environments were found to have more domed shells than turtles living in saltwater environments.eliminateShell shape became more flat in aquatic turtles as size increased and less flat in terrestrial turtles as size increased.eliminateThe turtle species studied were divided into four habitat types: marine, freshwater, mainland, and island.

How does increasing the temperature affect a reaction?A.An increase in temperature increases the reaction rate.B.An increase in temperature slows down the reaction.C.An increase in temperature changes equilibrium concentrations.D.An increase in temperature lowers the reaction's activation energy.SUBMITarrow_backPREVIOUS
