End products of biosynthetic pathways often act to block the initial step in that pathway This phenomenon is called?
metabolic inhibition
What is the difference between positive feedback control system negative feedback control system?
Positive feedback speeds up reactions and negative feedback slows them down. In electronics and control systems, positive feedback means the feedback gets added to the input and then goes as output. And negative feedback means that the output is input minus feedback (from output). This is the most basic and layman answer I can think of. In social and business terms, a positive feedback means a good response ( a praise for a product, or interest generation among the clients) and a negative feedback means a bad response (unhappy clients, criticism and the like ).
What are the similarities between pavlov's and skinner's work?
Both theorists studied how behaviors could be reinforced. While Skinner took Pavlov's work one step farther, they both used a stimulus and response method within their work. However, Skinner went farther to say that there is a limited number of repsonses that can be learned. In some instances you first must shape or introduce the initial stimulus for learning to take place.
If i have the initial and after temperature how would i be able to find the change in temperature?
You subtract the initial from the after, and the result is the change. If the initial temperature is 50º and the after is 70º, then the change is +20º.
What is the initial site for respiration?
diaphragm A+ Tim
When the initial stimulus produces a response that reinforces the stimulus the mechanism is called?
positive feedback
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.
In positive feedback the initial stimulus produces a response that the stimulus?
exagerrates the stimulus
Do negative feedback systems operate in such a way that the initial stimulus is shut off or reduced?
Yes
What are the example of negative and positive feedback in geography?
A negative feedback would be if the planet heats up, the glaciers will melt, lowering the albedo effect of the snow, and in turn causing the planet to heat up more That is positive feedback, not negative. Positive feedback enhances the initial stimulus, negative feedback reverses the initial stimulus. The planet starts by heating up, then heats up even more, which is positive feedback.
What is the mechanism of homeostasis whereby a step inhibits the initial signal in the series?
negative feedback
In a negative feedback loop the effector organ produces changes that are?
opposite in direction to the change produced by the initial stimulus
How might a person exhibit positive feedback communication?
Positive feedback increases the original stimulus. An example is labor contractions. The initial contraction signals the body to release hormones that increase the frequency and intensity of subsequent contractions.
What is the initial experience of a stimulus?
The initial experience of a stimulus involves the detection of the stimulus by sensory receptors in the body, such as in the eyes, ears, or skin. This triggers a neural response that sends signals to the brain for processing and interpretation, leading to the awareness and perception of the stimulus.
What term is defined as the visual impression that remains after the initial stimulus is removed?
afterimage
Just noticeable difference is a constant proportion of the intensity of an initial stimulus is this weber's law?
Yes, that's correct. Weber's law states that the just noticeable difference (JND) between two stimuli is proportional to the intensity of the initial stimulus. This means that the difference needed to perceive a change in stimulus intensity remains constant regardless of the initial intensity level.
When an initial process is reinforced by another process it is called what?
Positive Feedback
