In the cell, the function of the smooth endoplasmic reticulum is that it produce lipids, which are fats and oils. They also transport materials..
Because of the presence of both activation and inactivation gates, voltage-gated Na channels can be all of these.
- Sodium voltage-gated channels can be either closed, open, or inactive.
- Voltage-gated sodium channels are closed when at rest. Both an activation gate and an inactivation gate are present in voltage-gated sodium channels.
- Although the inactivation gate is open, the activation gate is closed. This conformation is closed but capable of opening. Some of the activation gates open as a result of membrane depolarization brought on by a stimulus.
- Both the activation and inactivation gates will be opened at this point. As sodium ions enter the cells, nearby activation gates will open.
- A greater amount of sodium will enter the cells as a result, initiating an action potential.
- Both gates open when certain depolarization thresholds are reached. Action potential increases to its maximum as sodium rushes into the cell.
- The inactivation gate will gradually close and the permeability of the membrane to sodium ions will decrease. The channel is now in a state known as "closed but not capable of opening."
- Up until the membrane potential reaches its resting state, this occurs. The channels once more assume the "closed but capable of opening" conformation when resting values are attained.

Answer - C. The time required for the Succession to Occur
Reasoning - Behind my answer is because the time the succession evolves and grows to build life and progress to improve and expand in each certain time period.
Research participants’ uses occipital lobes when they
are engage in tasks that require the construction of mental image. <span>The location
of occipital lobe is in
the back portion of the brain behind the parietal and temporal lobes that is primarily
responsible for processing visual information. It contains the brain's visual
processing system, which processes images from our eyes and links that
information with images stored in memory or called visual-spatial processing. Other
function includes movement and color recognition.</span>
