Which of these conditions indicate positive feedback has occurred?
aleksklad [387]

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.
