Levels of Organization - ANSWER-Chemical, Cellular, Tissue, Organ, Organ System,
Organism
*must be in the right order, smallest to largest*
Functions/processes that distinguish living from nonliving - ANSWER-Maintaining
boundaries, movement, responsiveness, digestion, metabolism, excretion, reproduction,
growth & development
Needs to maintain life - ANSWER-Nutrients, oxygen, water, appropriate temperature,
appropriate atmospheric pressure

,Sagittal plane - ANSWER-divided down the middle of the body, two symmetrically
halves, closer to middle of body = medial, further away from to middle of body = lateral,
in the middle of body = intermediate
Frontal plane - ANSWER-divides body into front and back halves, front of body =
anterior, back of body = posterior, (in animals) back side = dorsal, stomach side =
ventral
Transverse plane - ANSWER-divides body at the waist, above the waist = superior,
below the waist = inferior, (in animals) closer to head = cranial, closer to tail = caudal
