How does cell theory help scientists to research more efficiently? A. Because all living things are made of cells, scientists can study one Type: of cell B. and gain information about any organism with similar cells.
C. Because you must do research on cells of both living and nonliving things.
D. Because all cells are the same, many different experiments can be done on them.
E. Because you have done experiments on many Type:s of cells to draw a conclusion.

A

Explanation:

since living things are made up of cells,it is not difficult to study and draw conclusion This has reduced much stress on scientists

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."    

this is more of a statement than a question. is there answers to go along with this, or is it opinion based?
