16
Q

Increase in size of all or part of the organism

- due to an increase in cell number, cell size, or amount of substance surrounding the cell

A

Growth

17
Q

changes that an organism undergoes through time

A

Development

18
Q

change in cell structure and function from generalized to specialized

A

Differentiation

19
Q

Formation of new cells or new organism

A

Reproduction

20
Q

maintenance of a relatively constant environment within the body despite FLUCTUATIONS in either the external or internal environment
- Ability to maintain internal stability to compensate for environmental changes to function properly

A

Homeostasis

21
Q

Effector increases the stimulus which causes more of the effector to be produced

  • initial stimulus further stimulates the response
  • deviation from the setpoint increases
    ex: giving birth
A

POSITIVE FEEDBACK HOMEOSTASIS

22
Q

Effector decreases the stimulus and causes the production of the product to be stopped.

  • maintain homeostasis
  • any deviation from the setpoint decreases
  • does not prevent variation but maintains variation within a normal range
    ex: body temperature
A

NEGATIVE FEEDBACK HOMEOSTASIS
