Answer:
the branch of physics that deals with the deformation and flow of matter, especially the non-Newtonian flow of liquids and the plastic flow of solids.
If direct pressure with sterile dressing fails to immediately stop severe bleeding from an extremity, you should apply a tourniquet to the injured site.
<h3>What is severe bleeding?</h3>
The expression severe bleeding makes reference to an emergency situation in which blood is lost in excessive quantities, which may be avoided by applying a tourniquet to stop the movement of blood.
In conclusion, if direct pressure with sterile dressing fails to immediately stop severe bleeding from an extremity, you should apply a tourniquet to the injured site.

Answer:
( a ) Voltage gated channels - channel can open and close based on membrane potential. At rest, the channel is closed and it opens at threshold.
Explanation:
Voltage Gated Channels -
It is a channel with a cluster of proteins present in the membrane .
The function of voltage - gated channel is to open for the some values of membrane potential and close for others . In maximum cases , the relation between channel state and membrane potential is probabilistic and requires a time lag . The ion channel can even flip the conformations at an unpredictable times , the membrane potential even determines the rate of transition and the probability per unit time of each and every transition .
