What is the main difference between negative and positive feedback?
a. positive feedback leads to system instability, while negative feedback leads to system stability.

b. positive feedback is caused by human impact, while negative feedback occurs naturally.

c. negative feedback ultimately leads to an increase in the first variable, while positive feedback ultimately leads to a decrease in the first variable.

d. positive feedback occurs at a much faster rate than negative feedback.

Answer;

-Positive feedback leads to system instability, while negative feedback leads to system stability.

Explanation;

-Positive and negative feedbacks are control systems that help regulate process rates and homeostasis in the body. Both feedbacks are important for an organism to regulate its internal processes.

-In positive feedback, there is a direct positive correlation between the concentration and the process rate. One good example is how the endocrine system regulates the release of its hormones.  

- Negative feedback controls the process rate to prevent substance accumulation. Contrary to positive feedback, it reflects a negative correlation between the concentration and process rate. Most homeostatic procedures involve negative feedback as most mechanisms achieve equilibrium by going back to their original states.

The main difference in the positive and negative feedback is that Positive feedback leads to system instability. On the other hand negative feedback leads to system stability.

Further Explanation:

Positive and negative feedbacks are control systems in our body. They help in regulating the process rates and also maintain homeostasis in the body. Both the feedbacks are very important for an organism to regulate its internal processes.

In positive feedback mechanism, there is a direct positive correlation between the concentration and the process rate. One very common example of positive feedback is seen in endocrine system that regulates the secretion of their hormones. They are very least related to stability.

In the edback negative femechanism, there is a negative correlation in between the process rate and the concentration. They control the process rate to prevent substance accumulation. Majorly negative feedback is involved to maintain the homeostasis in the body. They help in achieving equilibrium state by going back to the normal state. They are very commonly related to stability and provide stability in the body.
