Question 3 (multiple choice worth 4 points)
(04.02 mc)
what evidence supports a conservation law?
6 co2 – coh1206 +6 02
6 co2 + 6h20 + light – coh1206+6 02
6 h2o + light – coh1206 + 6 02
6 002 – 3 coh1206 +3 02

6 CO2 + 6H20 + light – C6H1206+6 02

Explanation:  

The conservation law states that the number of atoms stay the same before and after a reaction. Consider the following reaction:

6 CO2 + 6H20 + light – C6H1206+6 02

There are 6 atoms of carbon before the reaction, after the reaction also the number of carbon remains 6.

There are 18 atoms of oxygen before the reaction. The number of oxygen remains 18 after the reaction.

There are 12 atoms of hydrogen before the reaction. The number of hydrogen remains 12 after the reaction.

Hence, this reaction is the proper evidence of the conservation law.

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.

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.
