Respuesta :
Answer;
A) Blood pressure decreases greatly; blood flow to the heart is inadequate, and blood pressure decreases.
Explanation;
-With negative feedback, the output reduces the original effect of the stimulus. While in a positive feedback system, the output enhances the original stimulus.
-Negative feedback is the most commonly used feedback loop in the body. Negative feedback is used to negate or counteract a stimulus without completely eradicating it.
-One key difference between the two feedback is that positive feedback loops are used to eradicate a stimulus. Another key difference is that responses through positive feedback become more amplified over time. So once a stimulus activates a positive feedback loop it is not turned off until the stimulus is completely removed.
The blood pressure reduces significantly, as the flow of blood to the heart is inadequate, and blood pressure decreases indicates the occurrence of positive feedback.
What is positive feedback mechanism?
It is a process in which the end products of an activity makes more of that activity to take place in a feedback loop. This enhances the original activity. The output enhances the original stimulus in a positive feedback system. On the other hand, the output diminishes the original effect of the stimulus in negative feedback.
In positive feedback, the responses become more amplified with time. Therefore, once, a stimulus instigates a positive feedback loop it is not turned off unless and until the withdrawal of stimulus is done.
Thus, the correct statement is option a.
