Convection keeps the earths surface warm
Answer: It is approximately the membrane potential at which the electrochemical gradient for Na+ is zero.
Explanation:
The charge in plasma membrane occurs with diffusion and electric fields.
For example, if there are two solutions, let's assume solution X and Solution Y are separated by a porous barrier (to diffuse in equal proportions).
The fundamental principle of diffusion states that solution from a high concentration diffuses to a lower concentration.
For instance, if the X solution contains 40 sodium ions and 40 chloride ions, the Y solution only has 30 sodium and 30 chloride ions. Due to the diffusion, these two solutions will mix and reach a steady-state.
The like charges repel, and opposite charges attract.
Answer:
Hypothesis
Explanation:
To make a hypothesis is to make an educated guess.
As the experts says, solar eclipse do not happen always like lunar
eclipses do that is visible for a long periods of time and are observable. Unlike
solar eclipse, it happens hundreds and thousands of years to see it. Few people
can only see solar eclipse, and those only those people
who are in the small region where the Moon's umbra strike's Earth can witness
one.
