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;
Kingdom, Division, Class, Order, Family, Genus and Species
Explanation;
-The plant kingdom is divided into three divisions namely Bryophyta, Pteridophyta and Spermatphyta.
-Division Bryophyta includes mosses and liverworts. Division Pteridophyta includes the ferns and horsetails. They show a greater variety and a greater ability than bryophyte.
-Division Spermatophyta comprises all the seed bearing plants. They are familiar green plants which produce seeds through flowers or cones. The division spermatophyte consists of two main subdivisions: Gymnospermatophyta and Angiospermatophyta, which are the divided into classes and so forth,.
Answer:
q1 : ribosomes because they are responsible for protein synthesis
q2 : by transporting potassium ions into the cell and sodium ions out of the cell maintaining a concentration gradient
q3 : seawater contains a high concentration of sodium and chlorine ions that the Atlantic cod gets rid of by actively transporting them out of its body
