1. true segmentation in which there is a serial repetition of body parts: metamerism
2. all animals are......: -multicellular
-heterotrophic
-eukaryotes
-lack cell walls
3. taxonomists estimated there to be how many species of animals dwelling on
land?: 30-100 million
4. -compose a hierarchical system in which each successive level builds on the
one below it
-represents increasing complexity (starting from molecular level to biosphere
level): biological levels of organization
1/3
, 5. which hierarchy does the animal body fall into?: -cellular
-tissue
-organ
-organ system
6. at the cellular level, animals are.....: composed of aggregates of cells
7. how do animal and plant cells differ?: animal cells lack the structural support of a cell wall
8. what happens as the complexity of the animal body plan increases?: groups of
cells differentiate
9. at the tissue level....: groups of cells become specialized to perform a specific function more eflciently than
the unspecialized cell
