Questions and Answers

Match the following classes of vertebrates with their key characteristics:

Amphibia = Undergo metamorphosis and typically have a larval stage in water and an adult stage on land. Reptilia = Have scales, lay eggs, and are cold-blooded. Aves = Have feathers, wings, and are warm-blooded. Mammalia = Have hair or fur, nurse their young with milk, and give birth to live young.

Match the following types of fish with their defining features:

Cartilaginous fish = Possess a skeleton made of cartilage and typically have placoid scales. Bony fish = Possess a skeleton made of bone and have cycloid or ctenoid scales. Jawless fish = Lack jaws and paired fins; possess a notochord throughout life. Ray-finned fish = Have fins supported by bony rays and a swim bladder for buoyancy.

Match the following vertebrate structures with their primary function:

Lateral line = Senses vibrations and pressure changes in the water. Swim bladder = Controls buoyancy in bony fish. Amniotic egg = Provides a protective environment for developing embryos in reptiles and birds. Gill slits = Facilitate gas exchange in aquatic vertebrates.

Match the terms related to vertebrate reproduction with their definitions:

Oviparous = Reproducing by laying eggs that hatch outside the body. Viviparous = Giving birth to live young that have developed inside the mother's body. Ovoviviparous = Producing eggs that hatch inside the mother's body before being released. Amniotic = An egg with a membrane providing a protective environment for the developing embryo.

Monotremes = Lay eggs but still produce milk to nourish their young. Marsupials = Give birth to relatively undeveloped young that continue to develop in a pouch. Placental mammals = Retain their young in the uterus for longer periods, nourishing them via a placenta. Eutherians = Possess a placenta to nourish the developing fetus during gestation.

Reptiles = Three-chambered heart (except crocodilians) with partial separation of pulmonary and systemic circuits. Birds and mammals = Four-chambered heart with complete separation of pulmonary and systemic circuits.
