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.
The correct answer is A. When free hydrogen ions and free hydroxyl ions are removed from solutions of acids and bases, the acidic and basic properties disappear.
The strength of the acid or base depends upon its degree of ionization. Since different acids and different bases dissociate or ionize to different extent in water so their degree of ionization is also different. Strong acids and strong bases ionize in water completely while the weaker acids or bases ionize partially. Ionization of the weak acids in water are in equilibrium. The degree of ionization is the ratio of the number of ionized molecules to the number of molecules which are dissolved in water. In case of acids the ionized molecules are hydrogen ions and in case of bases hydroxyl ions.
The answer would be C

Answer:Inducible;inducer
Explanation:
Induction is the phenomenon of increased synthesis of protein or and enzyme in response to certain signal. Such enzymes are called inducible and the signals are called inducer. Induction is turning ''on''the switch of a gene.
When M is present in the medium, M binds the repressor protein. The repressor-M complex is inactive which does not bind to the operator region of LM. Now RNAP can transcribe the structural genes of LM.
M switches the gene ''on''. Hence M is an inducer of LM. LM is an inducible operon
Gene duplication, mutation, or other processes can produce new genes and alleles and increase genetic variation. New genetic variation can be created within generations in a population, so a population with rapid reproduction rates will probably have high genetic variation.
