This is a personal question on Ethics. Without animals we would have to test products and medications on humans which could be really difficult and cause further issues. However, when animals are used scientists can see what would happen to another human and animals are treated much better than humans would
Answer:
The correct answer will be option D- blocking Cl channel.
Explanation:'
Quinidine is a stereoisomer of quinine derived from the bark of Cinchona plants which is used in the medication of the heart as class I antiarrhythmic agent. This alkaloid decreases the automaticity and increases the duration of the cellular action potential of the heart.
This alkaloid acts by blocking the neurotransmission through blocking of sodium and potassium channels responsible for the depolarization in non-nodal tissues like atrial cells, ventricular cells. This decrease in the neurotransmission of an action potential depends on the Ca⁺² ions and the quinidine can also act by blocking the Ca⁺² channels as well as B adrenergic receptor.
Thus, option D-blocking Cl channel is the correct answer.
The type of fixed prosthesis that could the dental assistant recommend to the patient for the replacement of the gold crown on tooth #28 would be a porcelain coronet with zirconia, whose benefits are high durability, resistance to bite, and decay.
<h3>What is Fixed Prosthesis?</h3>
The fixed prosthesis may be described as a component of the dental prosthesis that agitates the substitute and repair of teeth by artificial alternative methods that cannot be withdrawn or extracted from the mouth.
Another benefit of the porcelain crown with zirconia is also associated with aesthetic aspects, as this approach ensures greater naiveness with the prospect of reaching the color of the patient's innate teeth.
Without the usefulness of metal, the porcelain crown with zirconia obtains more remarkable biological compatibility and undersized provocative threat.
Therefore, it is well described above.
