development through animal history
/.primitive - Answer-meaning "very much like the ancestor"
/.opposite of primitive - Answer-relatively "derived"
/.what an animal needs to "make a living" - Answer-energy. needed to survive, grow,

facial expression, produces heat, antagonistic pairs
/.Organ System: Integumentary - Answer-Functions:
-Protects against environmental hazards
-Helps regulate body temperature
-Provides sensory information
Major Organs:
-Skin
-Hair
-Sweat glands
/.Organ System: Digestive - Answer-functions:
-digestion: breaking down food physically and chemically (enzymes work in lower pH,
controls pH in stomach)
-absorption
Major organs: esophagus, stomach, intestines

-Functions: Directs immediate responses to stimuli. Coordinates or moderates activities
of other organ systems. Provides and interprets sensory information about external
conditions.

nitrogenous waste
Osmoregulatory: maintaining proper solute concentration (kidneys, having certain cells
to take up and excrete solutes)
