Those are antidepressant drugs that
increase the level of neurotransmitters. Selective serotonin reuptake inhibitors (SSRIs) affect the process of neurotransmitters’ reabsorption back into nerve cells. This inhibitor prevents reuptake of serotonin and instead of that, the serotonin stays in the gap between the nerves-synapse.
Tricyclics are antidepressants that block the reabsorption of neurotransmitters, in this case, serotonin, and epinephrine. As a result, these chemicals are released into a synapse.
<span>Monoamine oxidase inhibitors (MAOIs) block the enzyme monoamine oxidase which breaks down serotonin, epinephrine, and dopamine. As a result, the levels of those neurotransmitters are increased.</span>
Answer:
c. Giraffes that stretch their necks more than other giraffes will have babies with longer necks.
Explanation:
Giraffes that stretch their necks will not have babies with longer necks. A trait only shows in next generation if it is genetically inherited i.e. the gametes carry the trait to the next generation.
When giraffes stretch their necks, they are modifying their actions in their life time which will have no effect on the gametes. Hence, this trait wont be passed to the next generation and babies will not have longer necks.
