Question

1. matching. what are the four stages of complete metamorphosis? 2. choose the best answer. the complex pattern of innate behavior is _________. reflexes hibernation instinct courtship 3. drag and drop the correct term for each definition. fan - shaped membranes supported by rigid spines that help the fish maintain balance, move and steer thin bony plates that are formed from the skin hard, living, mineralized tissue that most vertebrate possess feathery slits that take oxygen from water and release carbon dioxide as a waste gas a tough, flexible, bonelike material choices: gills, agnatha, bones, cartilage, osteichthyes, scales, fins

Explanation:

1. Complete metamorphosis in insects has four - egg, larva, pupa, adult. These are distinct life - stages with significant morphological changes.
2. Instinct is a complex pattern of innate behavior. Reflexes are simple, automatic responses. Hibernation is a state of inactivity for survival in harsh conditions. Courtship is a specific type of behavior related to mating.
3. Fan - shaped membranes supported by rigid spines for fish movement are fins. Thin bony plates from the skin are scales. Hard, living, mineralized tissue in vertebrates is bones. Feathery slits for gas exchange in water are gills. A tough, flexible, bonelike material is cartilage.

Answer:

1. Egg, Larva, Pupa, Adult
