An example of an exothermic animal is:

• A penguin

• An elephant

• A lizard

• A wolf

Bilateral symmetry means:

• The organism has no definite shape

• The body can be divided into identical right and left halves

• The body has multiple identical parts around a center

• The organism has three body sections

Which group of animals is characterized by having a vertebral column?

• Jellyfish

• Vertebrates

• Insects

• Worms

An asymmetrical organism is one that:

• Has a definite left and right side

• Has no particular pattern of symmetry

• Has multiple identical parts around a center

• Is perfectly balanced on both sides

Which of these animals is endothermic?

• Snake

• Frog

• Bird

• Fish

Starfish exhibit which type of symmetry?

• Asymmetrical

• Radial

• Bilateral

• None

Which characteristic is true of most exothermic animals?

• They can regulate their internal temperature

• They are all invertebrates

• Their body temperature varies with the environment

• They are all aquatic animals
