svetoff [14.1K]
<h2>Answer:</h2>

<u>Blood clotting</u> is a positive feedback.

<h2>Explanation:</h2>

All the physiological process occurring in the body are monitored by two types of mechanism called negative feedback and positive feedback.  

Positive feedback is the reaction which occurs with the feedback from the actions the system has performed. The blood clot occurs with palette formation which is regulated with the blood lose (continuous feedback).

Negative feedback is a reaction that is the invert of the change distinguished, meaning it capacities to decrease the change. A change is recognized by a receptor and an effector is made to incite a contrary impact which facilitates further reaction.  

The physiological process such as shivering, sweating and digestion are examples of negative feedback.

MrMuchimi

I = 200 ua

V = 70 mV

Power = ?

Formula: Power = IV

Solution:

Power = IV

= ( 200 x 10^-6 A ) x ( 70 x 10^-3 V )

Power = 1.4 x 10^-5 Watts

The power that the neuron release is 1.4 x 10^-5 Watts
