<span>Which of the following statements is true about cellular respiration?
</span>1. I believe the answer is It breaks down food to release energy.
<span>
Cellular respiration is a chemical reaction that turns food into energy. The food that mostly used by the organism is carbohydrate. The breakdown of carbohydrate needs oxygen to maximize energy produced. </span>Cellular respiration<span> will create carbon dioxide and water as the side product. Photosynthesis and respiration happen in the living organism.
</span><span>2. The answer is Diffusion
The question is asking the movement of carbon molecule between seawater(liquid) and air(gas). Gas like carbon dioxide or oxygen can move from the water into the air by diffusion. This allows the seawater organism to utilize oxygen and carbon that vital for its life. </span>
I don’t understand your questions can you elaborate
Since a water molecule is H2O, you would divide 126 hydrogen molecules by 2, and you would get 63. That means you have 63 double hydrogen molecules, and 58 oxygen molecules to pair up with them. So that means you could have 58 molecules of water, with 5 double hydrogen molecules, so basically 10 extra molecules of hydrogen along with the H2O molecules. Hope I helped! :)
