Answer:
The answer to your question is This molecule has 10 carbons and 20 hydrogens.
Explanation:
- Number of carbons
You can see the picture below, all the edges are carbons and they are numbered, there are 10 carbons.
- Number of hydrogens
Carbon 1 has 3 hydrogens
Carbon 2 has 2 hydrogens
Carbon 3 has 1 hydrogen
Carbon 4 has 2 hydrogens
Carbon 5 has 3 hydrogens
Carbon 6 has 2 hydrogens
Carbon 7 has 1 hydrogen
Carbon 8 has 1 hydrogen
Carbon 9 has 2 hydrogens
Carbon 10 has 3 hydrogens
Total number of hydrogens = 20
Answer: The theory of cheek cells is used for the identification of cheek cells.
Explanation:
The cells of cheek do not have cell wall. They have a cell membrane which allows on certain molecules to pass through it. The nucleus is located centrally in the cheek cells and it stores the DNA. It can be stained with the help of the methylene blue reagent. It appears blue in color which can be observed under the microscope. The cheek cells can be isolated from the buccal cavity by using cotton buds and cotton swabs can help in isolating the cells.
