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.
Several governments agree to limit the amount of fish harvested from an ocean is sustainable use. By limiting the fish caught, the governments are helping to ensure that the fish population will be able to remain healthy enough to meet the needs of future human populations.
Answer:
Hemophilia and color blindness are two common sex-linked conditions.

Color blindness is a vision defect that is transmitted by a recessive gene carried on the X chromosome. The disease is more common in men than in women. Haemophilia is a serious disease in which blood take an abnormally long time to clot which leads to uncontrolled bleeding.
