During photosynthesis, plants incorporate carbon dioxide into sugars and other organic compounds. The ratio of 12CO2 to 14CO2 incorporated into the sugars and other organic compounds should be equivalent to the ratio present in the atmosphere. A. TrueB. False

The correct answer is option A. "True".

Explanation:

The ratio of 12CO2 to 14CO2 is constant in the atmosphere and in all living things. The plants have no preference in incorporating either 12CO2 or 14CO2 during photosynthesis. Therefore, the ratio of both molecules is equivalent in both, the atmosphere and in the sugars and other organic compounds of the plants.

hydrogen is a compound or a single element and a element is a pure substence that cannot be separated into simpler subtances

clorine is a compound its a chemical substance that forms when two or more different elements combine

so both hydrogen and clorine are compounds
