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.
I know what quiz this is i am taking it now the options are
1.)Transport proteins move to large molecules from areas of low concentration to areas of high concentration using cellular energy
2.) Transport proteins move to large molecules from areas of low concentration to areas of high concentration without the use of cellular energy.
3.) Small molecules move from ares of high concentration to areas of low concentration using cellular energy to enter a cell.
4.)mall molecules move from ares of high concentration to areas of low concentration without the use of cellular energy.

Answer:
<em>A mutation in his offspring</em>
Explanation:
A mutation can be described as any change which occurs in the DNA of an organism. Mutations can be either heritable or non-heritable
If a mutation occurs in the gamete cells of a male, the mutation will be heritable and will occur in his offsprings.
Other options, like option D, is not correct because a mutation in the gamete cells will not cause a mutation in the somatic cells. Gamete cells are the sex cells and hence mutation will arise in the sex cells.
