Variation means difference in genetic makeup between individuals within a specie.
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.
The genotypes of its gametes would be TS, tS, Ts, and St. This would mean the answer would be C. Hopefully this helps you.
Large sources of fossil fuels are found in cold regions shows evidence of climate change.
<h3>What this map shows?</h3>
This map shows that large sources of fossil fuels are found in cold regions because fossil fuels are extracted from the living organisms body so in cold regions once there was a large number of organisms lived there. When they died the fossil fuel sources are formed.
So we can conclude that large sources of fossil fuels are found in cold regions shows evidence of climate change.
