What should be changed to make the following sentence true? "a theta wave is a very high amplitude pattern of brain activity that may in some cases occur in response to environmental stimuli."

The words "theta wave" should be changed to the phrase "K-complex."

Explanation:

Complex K is a type of where related to slow wave sleep. The k complex is a group of high amplitude waves that can occur spontaneously or relate to awakening relationships. That is, the K Complex is a very high amplitude pattern of brain activity that can, in some cases, occur in response to environmental stimuli.

On the other hand, Wave Theta is the state of mind where it is believed that you can create everything and change reality instantly.

the calvin cycle has three stages. in stage 1, the enzyme rubisco incorporates carbon dioxide into an organic molecule. in stage 2, the organic molecule is reduced. in stage 3, rubp, the molecule that starts the cycle, is regenerated so that the cycle can continue

4.) metal

"-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."
