I think the answer is B but I'm not sure sorry
Answer:
prolongs the anesthetic effect of the drug
Explanation:
The epinephrine acts as a vasoconstrictor agent to some local anesthetic drugs. The systemic absorption slows down with the addition of 5 micrograms per mL of epinephrine. The epinephrine enhances the anesthetic effect of the drugs. It act as a adjuvant in local anesthetic drugs. The adjuvant increases the effect of immune response. The epinephrine also act as drug for anaphylactic reaction during emergency. The dopamine receptors are present in CNS. The epinephrine is not involved in lowering blood pressure and low heart beat. The epinephrine stimulates secretion of prostaglandins.
Thus, option B is correct. So, the addition of epinephrine to some local anesthetic drugs <u>prolongs the anesthetic effect of the drug.</u>
Answer:
A population of mosquitoes develops resistance to a pesticide
Explanation:
Evolution can be defined as the way the characteristics of a species change over several generations. This process relies on natural selection - a mechanism in which individuals that are better adapted to their environment survive and reproduce most successfully.
A population of mosquitoes developing resistance to a pesticide is an example of adaptation. This is how mosquitoes become adapted to their environment and increase their chances of survival. Eventually, most of the mosquitoes will be resistant thanks to natural selection. This is how mosquitoes evolve.
This is why the fourth option is the correct one.
