What is a control mechanism that responds to a stimulus by decreasing its intensity called?
Mimiklein
There are two kinds of feedback in the control of the body. Negative feedback occurs when a change happens in the body that makes the body beyond it's homeostatic level. Negative feedback reverses those changes and returns the body back to it's normal stage. Positive feedback occurs to temporarily amplify or enforce the change that is occurring. This process causes a number of increases until a signal is sent to the brain to stop the process.

What is a signal to which an organism responds?
stimulus
When the initial stimulus produces a response that reinforces the stimulus the mechanism is called?
positive feedback
Receptors provide information about the intensity of a stimulus through?
the frequency of their action potentials
How does the brain perceive the intensity of a stimulus?
There are a number of different ways that the brain perceives stimuli. If a person is hurt, the brain sends a reaction to the body. If something good happens, the brain sends good reactions to the body.
How does moss respond to stimulus?

What is a signal to which an organism responds?
stimulus
What is a singnal to which an oranism responds?
Stimulus
When an initial stimulus produces a response that exaggerates stimulus called what mechanism?
Exaggerating the stimulus is also seen as amplifying the stimulus. This is seen in outer ear hair cells.The mechanism you refer to is probably a positive feedback mechanism: more of the stimulus causes more of the stimulus. This is in contrast to a negative feedback mechanism, whereby more stimulus results in processes that strive to attenuate (lessen) that stimulus.

What is a physical or chemical change in an organism's environment to which it responds?
A physical or chemical change in an organisms environment to which it responds is a stimulus.
What are the four characteristics of a stimulus in stimulus coding?
The characteristics are modality (type of stimulus), intensity (strength of stimulus), duration (length of stimulus), and location (where the stimulus occurred).
When the initial stimulus produces a response that reinforces the stimulus the mechanism is called?
positive feedback
