Thousands of years ago, the jaws and teeth of jaguars were more varied in size than they are today. During a period of climate change about 11,000 years ago, jaguars faced a shortage of food. There were fewer mammals to eat, so the jaguars had to eat shelled reptiles. The jaguars with the largest jaws and teeth could most easily eat the shelled reptiles. Which of the following statements best explains why large jaws and teeth are common characteristics in jaguars today? Jaguars with smallest jaws and teeth died out completely. Jaguars with the smallest jaws and teeth were not able to mate. Jaguars with the largest jaws and teeth survived and reproduced more successfully than the other jaguars. Jaguars with the largest jaws and teeth strengthened them by using them more frequently than the other jaguars.

In what way do teleosts and other fish benefit from having a bony operculum? it prevents water outside of the body from flowing backward into the gills when the buccal (mouth) cavity is expanded it serves as a rotating joint that allows them to rapidly project their jaws forward more rapidly it forms a joint between the head and pectoral girdle and allow for a greater amount of head rotation it prevents the brain from being damaged by the lateral bending of fish attempting to escape from the mouth
