Meditation is a practice of sitting still and quiet for minutes or even hours. It has been practiced for thousands of years and is even a part of religious practices for some people. Carefully controlled, repeated measurements of brain activity have shown that meditation does increase certain chemicals in the brain and even grows the part of the brain that helps people connect with their current surroundings and activities. Are claims about the effects of meditation most likely scientific or pseudoscientific? scientific, because people have been claiming for thousands of years that meditation helps them scientific, because observations of brain growth and chemicals are made carefully and repeatedly pseudoscientific, because practices that are related to religion are based on beliefs and are subjective pseudoscientific, because people have made claims about it but scientific observations have not been made Mark this and return

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
