|
|
cellular composition is?
|
must have at least 1 cell
|
|
|
metabolism and excretion is?
|
metabolism requires excretion, seperation of wastes from the tissues and their elimination from the body
|
|
|
responsivness and movement is?
|
the ability or organisms to sense and react to stimuli
|
|
|
Evolution is?
|
all living species exhibit genetic change from generation to generation and therefore evolve
|
|
|
Development is?
|
any change in form or function over the livetime of the organism
|
|
|
2 processes if development are?
|
1. differetiation
2. growth |
|
|
Differentiation is?
|
the transformation of cells with no specialized task

|
|
Growth is?
|
is an increase in size
|
|
|
Reproduction is?
|
Organisms can produce copies of themselves
|
|
|
Homeostasis is?
|
the ability to maintain a stable environment
Think of total organism |
|
|
What is a receptor?
|
monitors the environment and responds to changes(stimuli)
|
|
|
What is the control center?
|
it determines the set point at which the variable is maintained
|
|
|
What is the effector?
|
it provides the means to respond to the stimulus
|
|
|
What is negative feedback?
|
the output shuts off the original stimulus (fixes the problem)(eliminates the stimula, turns it off)
|
|
|
What is positive feedback?
|
it turns something on
|
|
|
What is the anatomical position?
|
-body is in erect standing position
-head, eyes, and toes are directed anteriorly -upper extremeties are by the side of the torso and palms faced forward(anterior) -lower extremities are positioned with heels touching posteriorly and the great toe thouching anteriorly |
|
