1 answer:

3 0

N the brain, dopamine functions as a neurotransmitter—a chemical released by neurons (nerve cells) to send signals to other nerve cells. The brain includes several distinct dopamine pathways, one of which plays a major role in reward-motivated behavior. Most types of rewards increase the level of dopamine in the brain, and many addictive drugs increase dopamine neuronal activity. Other brain dopamine pathways are involved in motor control and in controlling the release of various hormones. These pathways and cell groups form a dopamine system which is neuromodulatory.

Halons and cfc’s both _______. a. inhibit ozone formation b. cause ozone formation in the troposphere c. destroy ozone in the st

stepladder [879]

Halons and cfc’s both destroy ozone layer in the stratosphere.

Chemicals with carbon, chlorine, and fluorine atoms are known as chlorofluorocarbons (CFCs), and they are neither poisonous nor combustible.
They are employed as solvents, refrigerants, blowing agents for foams and packaging materials, and in the production of aerosol sprays.
Halons, hydrochlorofluorocarbons, and chlorofluorocarbons all damage the ozone layer, which protects the planet from damaging ultraviolet (UV-B) rays from the sun.

Additionally warming the earth's lower atmosphere, CFCs and HCFCs alter the climate on a global scale.

Life on earth is made possible by the stratospheric ozone layer, which protects the planet from the sun's harmful ultraviolet (UV-B) rays.

Ozone in the upper atmosphere is destroyed by man-made substances such halons, hydrofluorocarbons, and chlorofluorocarbons (CFCs)
