What is the driving force of the membrane?
The driving force is explained by two factors: voltage gradient and concentration gradient. When there are more ions inside of a cell than outside of a cell, the concentration gradient is pushing the ion to exit the cell. This is simple diffusion. If that ion carries a negative charge then it also wants to exit the cell because the outside environment is slightly more positive.So if you add both voltage gradient and concentration gradient you get the driving force. In the example above both gradients are pushing the ion outside of the cell. Sometimes you can have the gradients going in opposites and then the driving force will be determined on which gradient is stronger.
The circulation of blood through the vascular system is influenced by?
Blood flow can be affected by such factors as clots and blood pressure which are in turn affected by obesity and genetics.
What factors contribute to the membrane potential of a cell?
There are many factors that contribute to the membrane potential of a cell. The driving force of ions which are a summation of voltage gradient and concentration gradient are an important one. Also other proteins and amino acids contribute to the cell's membrane potential.
What particle from the sun is said to have a been a driving force behind the beginnings of life and creation of the atmosphere on Earth?
The particle from the sun that is said to have a been a driving force behind the beginnings of life and creation of the atmosphere on earth is know as a meteoroid. This changed the dynamics and circulation of the winds which significantly affected the atmosphere of the earth.
What is the primary driving force that produces glomerular filtration?
Osmotic pressure in the blood vessel or cell pushes water from a place with a lower concentration of dissolved solids (there is more water on that side, proportionally), to the other side if there is a higher concentration of dissolved solids (because proportionally there is less water)
What is the driving force for fluid flow?
pressure gradient is
What is the primary driving force of wind?

What is the driving force for blood flow through the systemic circuit?

What are the three main driving forces of air motion?

What is true about passive transport?
The concentration gradient is the driving force.

What is the driving force for the movement of gas think of the concentration gradient?
wind
What is true about all passive transports?
The concentration gradient is the driving force.
What is the gradient called that is the driving force for the movement of water and dissolved solutes from the arterial ends of blood capillaries?
The blood pressure in the capillaries at arterial end is about 25 to 30 mm of Mercury. The oncotic pressure of the plasma proteins is about 22 mm of mercury. So there is net force, which drives out the fluid in the interstitial space. The fluid is sucked back at the venous end of the capillaries by the oncotic pressure of the plasma proteins. It should be called as pressure gradient.

Blood flow can be affected by such factors as clots and blood pressure which are in turn affected by obesity and genetics.
What is the difference between evaporation and distillation?
Evaporation can happens at any temperature below boiling point under atmosphere pressure. Every liquid exhibits vapor pressure on it's surface. In case of evaporation, vapor may be displaced from the surface of the liquid due to diffusion.In case of distillation, liquid boils to give vapors. (boiling happens when the vapor pressure equals to the pressure of the system)
Is hydrogen gradient across the mitochondrial inner membrane a cellular energy currency?
ATP molecules are essentially cellular energy currency. The hydrogen gradient (or proton gradient as it is technically called) is responsible for the functioning of a protein complex called ATP synthase which in turn is responsible for the synthesis of ATP molecules. Therefore, the proton gradient is the driving force for the synthesis of ATP molecules.
