As the ion channel opens and allows its movement in an energetical direction. Then it redistributes these ions in opposite direction back across the membrane.
The Na channel opens as the membrane is hyperpolarized. The averaged collective response of single channels resembles the time course of the macroscopic current. Macroscopic currents are blocked by Tetrodotoxin (TTX) but not microscopic currents.
Opening and closing of Na channels are concentration dependent. The function of ion channels inorganic ions (like Na, K, Ca or Cl) to rapidly diffuse their electrochemical gradients that is across the lipid bilayer.

The left bronchus is smaller and longer than the right main bronchus (approximately 5 cm or 1.5 inches).
<h3>What is the difference between primary secondary and tertiary bronchi?</h3>
The primary bronchi department from the trachea and they are the right and left primary bronchi. those bronchi are the widest and they enter the lung. After coming into the lungs, the bronchi retain to branch in addition into the secondary bronchi, referred to as lobar bronchi, which then branch into tertiary (segmental) bronchi.

Correct Statements are -
- They’re made up of more than one substance.
- They’re readily available in nature.
<h3>
What are Composite Materials?</h3>
- Composite materials are created by combining two or more substances with dissimilar properties.
- Composite materials have distinct properties that distinguish them from their constituents, and the constituents can be easily distinguished within the composite materials because they do not blend together.
- Some composite materials are abundant in nature. Wood, for example, is a composite material made up of cellulose and lignin.

Answer:
The fight-or-flight-or-freeze or the fight-flight response (also called hyperarousal or the acute stress response) is a physiological reaction that occurs in response to a perceived harmful event, attack, or threat to survival.
Prokaryotic cells have various shapes; the four basic shapes of bacteria are: Cocci – spherical. Bacilli – rod-shaped. Spirochaete – spiral-shaped.
