The answer to this question would be: <span> C) carbon dioxide and water
In cellular respiration, the glucose will react with oxygen, resulting in ATP, carbon dioxide and water. Adenosine triphosphate or ATP is the main product of this reaction since it can be used to produce energy. So, water and carbon dioxide would be the by-product.</span>
Answer:
To observe the cheek cell,
-
Take a tooth pick use its blunt side to scrap inside the mouth.
- You will see some deposition on the blunt side of tooth pick, make a smear on the clean slide in the center using that tooth pick.
- Add a drop of methylene blue solution and place a coverslip, make sure that bubbles are avoided i.e. coverslip should be placed in the inclined manner.
- Remove the excess solution and observe it under the microscope first under 4X and then under 10X.
Observation:
- The cells observed are squamous epithelial cells. The small blue dots seen inside will be the bacteria from our teeth and mouth.
The best way to determine the presence of halogens is by adding a silver nitrate solution to the solvent. This is because all halogens, except for fluorine, produce a precipitate with silver nitrate solution.Chlorine produces a white precipitate, bromine produces a pale cream colored precipitate and iodine produces a yellow colored precipitate.
If further testing is required, concentrated sulfuric acid may be added. The sulfuric acid will produce misty fumes with fluorine and chlorine, brown fumes with bromine and purple fumes with iodine.
hope this helped :)
