During the S-phase of the cell cycle, DNA makes an exact copy of itself in one of the following processes. The process that makes an exact copy of a cell’s DNA is called a. translationb. transcription c. replicationd. synthesis

Replication

Explanation:

During the process of replication DNA (genetic material) makes copies of itself to make two identical DNA molecules. it is one the most basic processes within a cell.

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."    

it's not c. i took the quiz and got it wrong. so my best guess is b.

have a great day, and hope this .
