nuclear fusion and gravitational contraction.
I'm cheating on my astronomy homework too :)

Nuclear fusion is the primary process in stars that generates energy by fusing lighter elements into heavier ones. Gravitational contraction is another process where a star generates energy by converting gravitational potential energy into thermal energy. Both processes contribute to maintaining the star's internal thermal pressure.

Which two energy sources can help a star maintain its internal thermal pressure?
Nuclear fusion and radiation pressure are the two energy sources that help a star maintain its internal thermal pressure. Nuclear fusion in the star's core generates heat and energy, while radiation pressure from the intense photons produced by fusion counteracts the gravitational forces trying to collapse the star.
What is the difference between pressure and stress?
Pressure is the force applied over a specific area, while stress is the internal force created within a material in response to an applied load. Pressure is usually external and uniform, while stress is internal and can vary depending on the material's properties.
How do you generate 1000lbs of pressure?
To generate 1000lbs of pressure, you can use a hydraulic press that applies force through a piston on a confined fluid. By increasing the force on the piston, you can generate the desired pressure. Alternatively, you can also use mechanical devices such as a torque wrench to apply pressure through rotational force.
What is internal static pressure?
Internal static pressure is the pressure that exists within a closed system when there is no flow of fluid. It is the force per unit area exerted by the fluid against the walls or boundaries of the system. This pressure remains constant as long as there are no changes in temperature or volume within the system.
Is pressure internal or external?
It can be either.
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.
If a cell is in balance with its environment then?
it is able to maintain internal stability despite fluctuations in external conditions. This balance is crucial for proper functioning and survival of the cell. It involves processes such as maintaining ion concentrations, controlling osmotic pressure, and regulating temperature.

How you can generate electricity through muscles?
Muscles can generate pressure. Using transducers, pressure can be converted into electricity.
What is the difference between pressure and stress?
Pressure is the force applied over a specific area, while stress is the internal force created within a material in response to an applied load. Pressure is usually external and uniform, while stress is internal and can vary depending on the material's properties.
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.
What do plasma proteins that remain in the blood capillaries help?
Maintain the osmotic pressure of the blood
How do you generate force and momentum?
You can generate force and momentum by applying pressure.
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 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.
Concepts of homeostasis?
Homeostasis refers to the body's ability to maintain internal stability by regulating various physiological processes such as temperature, blood sugar levels, and blood pressure. It involves mechanisms that detect and respond to deviations from the ideal state to keep the body in balance and functioning properly. Examples include sweating to cool the body down when it's too hot or shivering to generate heat when it's too cold.
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.
