Answer:
- <u>Oxygen is combined with the carbon atoms left from the glucose molecule.</u>
Explanation:
Plants are producers that make polysaccharides through the process of photosynthesis. These polysaccharides, are used to store chemical energy stably in their covalent bonds.
Mitochondria break down sugars in cellular respiration. Aerobic respiration for instance, breaks down glucose in the presence of oxygen, which produces carbon dioxide and water, while transferring energy to the molecule ADP, to produce ATP (adenosine triphosphate).
C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP
glucose+ oxygen → carbon dioxide+ water+ energy
Oxygen is the final electron acceptor, it combines with the leftover carbons in respiration resulting in the waste product .
<h3><u>Answer;</u></h3>
Potassium-40 has a half life of 1.25 billion years.
<h3><u>Explanation;</u></h3>
New amount = Original amount × (1/2)^n ; where n is the number of half lives.
Original amount is 50 atoms
New amount is 25 atoms
Therefore;
25 = 50 × (1/2)^n
1/2 = (1/2)^n
Thus; n = 1
n = 1 which is equivalent to 1.25 billion years
Therefore;
<u>Potassium-40 has a half life of 1.25 billion years.</u>
