all of the statements are correct

which

what is a measurement of the earth’s history divided into time periods?

> geologic time scale <

radioactive elements

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
