Answer:
If Clark had no ions in his nervous system, he would not be able to generate an action potentials.
Explanation:
An action potential occurs when a stimulus causes sodium channels to open in a neuron. Sodium floods in, making the inside of the cell more negative and the outside more positive. This is known as depolarization. Then, the Potassium channels open to allow Potassium out (Repolarization). A few too many K+ ions will leave the cell (Hyperpolarization), and finally, the Sodium-Potassium pump will bring the cell back to resting potential.
As you can see, the Sodium and Potassium ions are <em>essential</em> to action potentials in the nervous system. If Clark had no ions in his system, he would not be able to send any action potentials at all.
Answer: lower atmospheric pressure
Explanation:
During the inspiration process the diaphragm, and external intercostal muscles. The contraction of the diaphragm causes the increase in the size of the thoracic cavity this causes the contraction of the external intercostal muscles. As a result of this the ribs and the sternum get elevated.
This causes the lungs to expand, and increasing the volume of the air passage. In this response the air pressure inside the lungs reduces below the air outside the body. Thus this facilitates the movement of the gases from a region of high pressure to low pressure, this way the air rushes into the lungs.
The building blocks of lipids are one glycerol molecule and at least one fatty acid, with a maximum of three fatty acids.
Hope this helped you, and have an amazing day.
