To obtain food, water, and oxygen
Keep internal conditions stable (Homeostasis)
Move in some way
Reproduce

Asymmetrical
What type of symmetry does a dog have
Bilateral
Structures and behaviors that allow animals to perform their functions are called
Adaptations

If only one line of symmetry can be drawn to divide it into halves that are mirror images
Bilateral Symmetry
