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>

Endometriosis
This occurs when the tissue that lines the womb called endometrium proliferates to other regions outside the uterus. The displaced endometrium is still subject to reproductive hormonal changes such as thickening and breakdown as it occurs in the womb. This causes complications with painful symptoms.
Answer
Hi,
An object with the largest size will have a large gravitational force acting on it. Explanation
The gravitation force increases with increase in size of an object. An object that has twice as much mass will exert two times as much gravitational pull on other objects. An object with greater mass attracts the earth more strongly that the other one with smaller mass. On the earth’s space, the more massive objects will exert stronger gravitational forces.
Best wishes!
Khan Academy is great! Also, Alison (it's a website) has some free courses as well.
