The answer should be B). Helpful traits passed to the next generation through reproduction.
B is correct because in natural selection, if a population cannot adapt over time it will be “naturally selected” and die off, or be near extinction due to non-adaptive ness. Hope this helped!
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>
Explanation:
Typical roots contain three different sections, or zones: the meristematic zone, the zone of elongation, and the zone of differentiation. In the meristematic zone, named after the apical meristem, the plant cells undergo rapid mitotic division, creating new cells for root growth.
