Zhenyuanlong suni (Figure 2) was a seven-foot-long, Early Cretaceous predatory dinosaur with short feathered arms, long legs with sickle claws on their feet, a body covered in short feathers, and a long tail supporting long feathered vanes.

The metamorphosis of a tadpole to an adult frog involves a thorough reconstruction of the animal's body. All the structural and physiological changes must be complete or the frog will not survive this transformation. Which type of regulation would ensure that the animal completed its transformation? A) feedback inhibition B) negative feedback C) positive feedback D) enzymatic catalysis 20.) Elephants can often be observed cooling off by spraying water over their bodies with their trunks. What type of heat b exchange does this practice encourage? A) conduction B) convection C) radiation D) evaporation 21.) In which of the following examples does an ectothermic organism that have the fewest behavioral options to adjust its body temperature? A) a frog in partially shaded pond B) a lizard in a fully shaded cage C) a hawk in a forest D) an adult wasp in a hiveExplanation / Answer
