The answer is
"Dopamine".
<span>Some drugs fundamentally influence one neurotransmitter or
class of neurotransmitters. For instance, prescription opioids and heroin
deliver impacts that are like (however more articulated than) those created by
the neurotransmitters endorphin and enkephalin: expanded absence of pain,
reduced readiness, and low breath. Different medications upset more than one
sort of neurotransmitter. Cocaine, for instance, joins to structures that
manage dopamine, prompting increments in dopamine activity and creating
euphoria; it likewise delivers changes in norepinephrine and glutamate
frameworks that cause stimulant impacts.</span>

Answer:
From this it can be deduced that the fresh water is hypotonic and the salt solution is hypertonic to the cells of the celery stalks.
Explanation:
When submerged in water, the celery stalks become stiff and hard, this shows that water moves within the stalk, thus, water is hypotonic in comparison to the celery stalk. Therefore, water moves from the region of higher concentration to the region of lower concentration.
When the same celery stalk is administered into the 0.15 M solution it turns soft, which shows that water from the celery stalk moves out. Thus, the salt solution is hypertonic in comparison to the celery stalk. Therefore, freshwater is hypertonic and the solution of salt is hypertonic to the celery stalk cells.
Se crean nuevas células a partir de un proceso llamado división celular. Las nuevas células se producen cuando una célula, llamada célula madre, se divide en nuevas células llamadas células hijas.
