The Answer is B i just took the test. Enjoy, i also just looked it up on a quizlet. That's another website you can use if it comes up in the search for the question.
Answer:
The correct answer is - when action potentials trigger the release of neurotransmitters.
Explanation:
Communication between neurons takes place by signaling that can be either chemical signaling or electrical signals. Communication between neurons occurs at very small gaps known as synapses.
These synapses have two specialized cells that help two neurons communicate by one to another to allow for chemical transmission. The chemical that isreleased due to the stimulation of the action potential in order to communicate the neurons are known as neurotransmitters that allow for transmission.
The effector in a negative feedback system acts to counter any changes made to a particular property. If it were positive feedback, it would amplify the change and make it more extreme
Above the troposphere lies the stratosphere where jet airplanes fly. Temperatures increase with altitude because of increasing amounts of ozone. The ozone layer within the stratosphere absorbs harmful ultraviolet rays of sunlight. As the mesosphere extends upward above the stratosphere, temperatures decrease.
