What is the difference between pressure and stress?
Pressure is the external force acting over a unit surface area of a material. Stress is an internal force acting over a cross sectional area within the material. It may also be thought of as the internal resistive response of a material to the applied external pressure. They both have the units of force / area. think it as- suppose we have a cubical solid mass. we apply external force of few magnitude on it and this force will try to deform the cube. at the same instant an internal force will generate within the cube that will try to maintain the shape and size of the cube i.e. this internal force will work against the applied external force. this induced force within the cube is stress.
What is internal static pressure?
When you are talking you send your sound pressure, but around you is the atmospheric pressure and your waves are on top of that. You are changing a bit but not noticable that nearly static air pressure. http://en.wikipedia.org/wiki/Atmospheric_pressure
Is pressure internal or external?
It can be either.
How are tornadoes and thunderstorms tied to air pressure?
Tornadoes, which are produced by thunderstorms, generate small areas of very low pressure. Thunderstorms, which are fueled by rising air, generate low pressure as well, but over a broader area. Thunderstorms in turn usually form with large-scale low pressure systems.
What is a wolf's homeostasis?
A wolf's homeostasis refers to the internal balance it maintains to survive and function properly. This includes regulating body temperature, blood pressure, and other physiological processes within a stable range despite changes in the external environment. Wolves have evolved mechanisms to adapt to various conditions and maintain their internal equilibrium.

How you can generate electricity through muscles?
Muscles can generate pressure. Using transducers, pressure can be converted into electricity.
What helps to maintain a stable internal environment?
Homeostasis means to maintain a stable internal environment. Lack of homeostasis is disease. All of the body organs do this. They keep the systems working at a set range. Blood pressure, glucose levels, etc. The main organs involved are the liver, kidneys, lungs and nervous system.
How do you generate force and momentum?
You can generate force and momentum by applying pressure.
What do plasma proteins that remain in the blood capillaries help?
Maintain the osmotic pressure of the blood
How physiological processes limit damage?
haemorrhage prevented by platelet aggregation and agglutination (clotting) and vasoconstriction to maintain blood pressure/perfusion pressure. formation of clot through platelet clumping and binding with protein fibrin.
Which characteristic of living things relates to stability?
the tendency to maintain temperature, for one is consistent among every living thing. as is internal pressure relative to the external environment. your question actually refers to homeostasis, which is the property of living things to maintain a stable internal environment relative to the external environment.

How would the excretory system maintain stable internal conditions during a crisis?
The kidneys retain salt when the blood pressure is low. This keeps fluid in the body, thus maintaining the blood pressure. The kidneys cause vasoconstriction in the body when the blood pressure is low. This raises the blood pressure.
How to Maintain water pressure?
If you have water pressure and wish to maintain it, do not cause flow in the line, which will reduce pressure due to friction. To keep pressure up, reduce friction by increasing the line size or eliminating some other restriction. To maintain water pressure in the line, it might have a pressure transmitter and Booster pump to maintain the set Pressure in the network & I disagree the above answer to maintain the pressure we shouldn't increase the line size by reducing the line size we can increase/Maintain the pressure to overcome the losses in the Network
