Answer:
A. Sodium is needed to generate an action potential.
Explanation:
Action potentials are generated by the special types of the voltage-gated channels which are embedded in the plasma membrane of the cell.
These channels are shut when the membrane potential is near zero and the voltage-gated channels open only when the membrane potential is more than the threshold voltage.
When the channels are open then they allow the flow of sodium ions which ultimately changes the electrochemical gradient which rises the membrane potential. This rise in membrane potential generates the action potential.
Answer:
high; low; energy.
Explanation:
Diffusion can be defined as the movement of gas molecules from a region of high concentration to a region of lower concentration until an equilibrium is attained or reached. This mixing of gas molecules in the liquid or gaseous state is due to their kinetic energy of random motion i.e without requiring bulk motion.
This ultimately implies that, diffusion is a phenomenon through which gas molecules in either a gaseous or liquid state spread out in response to a concentration gradient, which is simply the difference in concentration of the gases across a space.
During diffusion, molecules move from areas of high concentration to areas of low concentration. Also, diffusion does not require energy to move molecules.
In conclusion, increasing the surface area of a gas increases its collision rate and it's considered to be an evolutionary strategy that maximizes the diffusion of gas molecules because it catalyzes the rate of a gaseous reaction.
Well A seems to be the answer because during the night time your rods are stimulated more, meaning you use the more at night
Answer:
area of ocean or lake surface over which the wind blows in an essentially constant direction, thus generating waves the term also is used as a synonym for fetch length which is the horizontal distance over which wave-generating winds blow
