Stimulus Response Model Biology
96 observed that the b wave amplitude increased with increasing stimulus strength until it reached a peak and then decreased for stronger stimuli.
Stimulus response model biology. The stimulus is a change in the environment whether it be internal or external that can be detected and responded to. This resource is a revision powerpoint for wjec a level biology focusing on the stimulus response model. The stimulus response function acquired by measuring b wave peak amplitudes in response to brief flashes over a range of increasing stimulus strengths has a characteristic inverted u shape.
In the cut and thrust of homeostasis students will have to know the stimulus response model and how to apply it to topics like temperature carbon dioxide blood glucose water and blood pressure regulation. The stimulus response model a level biology no rating 0 customer reviews. A biologic stimulus is any external change in the environment that can be detected by an organism.
