|
Comparative anatomy |
Study of more than one species in order to examine structural similarities and difference, and analyze evolutionary trends. |
|

|
|
Organization |
Living things exhibit a higher level of organization than the nonliving world around them |
|
|
Cellular composition |
living matter is always compartmentalized into one or more cells |
|
|
Hierarchy of Complexity |
Atoms>Molecules>Organelles>Cells>Tissues>Organs>Organ Systems>Organism |
|
|
Metabolism |
Sum of all internal chemical change |
|
|
Anabolism |
Synthesis of compounds |
|
|
Catabolism |
Breakdown of compounds |
|
|
Excretion |
Elimination of waste |
|
|
Responsiveness and Movement |
Sense and react to stimuli |
|
|
Development |
Differentiation-cells specialize their functions Growth-an increase in size in response to metabolic processes |
|
|
Reproduction |
Asexual-produce an exact copy of itself Sexual-complex, ability to pass genes to offspring with modifications |
|
|
Evolution |
Change in the genetic structure of a population from one generation to the next |
|
|
Homeostasis |
The body's ability to detect change, activate mechanisms that oppose it, and thereby maintain relatively stable internal conditions, regardless of the external conditions |
|
|
Negative feedback, |
Body senses a change and activates mechanisms to reverse it Fluctuation around an average-dynamic equilibrium |
|
|
Receptor |
Senses change in the body |
|
|
Integrating center |
Control center that processes the sensory information |
|
|
Effector |
Carries out the final corrective action to restore homeostasis |
|
|
Positive feedback |
Self-amplifying cycle, leads to greater change in the same direction occurs with childbirth, blood clotting, protein digestion, generation of nerve signals |
