When preparing a wet mount specimen for viewing, the specimen should be covered with
A cover slip.
Clear paper.
Transparent tape.
Another glass slide.
The Correct Answer is A
Choice A rationale: A cover slip is correct because a cover slip is a thin, transparent piece of glass or plastic that can be placed over the specimen on the slide. A cover slip protects the specimen from drying out, dust, or damage, and creates a flat surface for viewing under the microscope.
Choice B rationale: Clear paper is incorrect because clear paper is not suitable for covering a wet mount specimen. Clear paper is a type of paper that is transparent or translucent, but it is not thin or flat enough to fit over the specimen on the slide. Clear paper can also interfere with the passage of light or distort the image of the specimen.
Choice C rationale: Transparent tape is incorrect because transparent tape is also not suitable for covering a wet mount specimen. Transparent tape is a type of adhesive tape that is clear or see-through, but it is sticky and can damage the specimen or the slide. Transparent tape can also affect the quality of the image or the focus of the microscope.
Choice D rationale: Another glass slide is incorrect because another glass slide is too thick and heavy to cover a wet mount specimen. Another glass slide is a thin, flat piece of glass or plastic that can be used to place the specimen on, but not over it. Another glass slide can also crush the specimen or block the light source of the microscope.

Correct Answer is {"dropdown-group-1":"C"}
Explanation
Choice A rationale: Osmotic is incorrect because osmotic is an adjective that describes the movement of water across a semipermeable membrane, not a type of solution. Osmosis is the process by which water moves from a region of high water concentration to a region of low water concentration.
Choice B rationale: Isotonic is incorrect because isotonic is a type of solution that has the same concentration of water as the cell placed in the solution. In an isotonic solution, there is no net movement of water across the cell membrane.
Choice C rationale: Hypertonic is correct because hypertonic is a type of solution that has a lower concentration of water than the cell placed in the solution. In a hypertonic solution, water moves out of the cell and into the solution by osmosis, causing the cell to shrink.
Choice D rationale: Diffusive is incorrect because diffusive is an adjective that describes the movement of molecules from a region of high concentration to a region of low concentration, not a type of solution. Diffusion is the process by which molecules move across a membrane or a space due to their random motion.
Choice E rationale: Hypotonic is incorrect because hypotonic is a type of solution that has a higher concentration of water than the cell placed in the solution. In a hypotonic solution, water moves into the cell and out of the solution by osmosis, causing the cell to swell.
Correct Answer is B
Explanation
The total magnification of a microscope is calculated by multiplying the magnification of the objective lens and the magnification of the eyepiece lens. Therefore, using a 10× objective lens with a 10× eyepiece lens would result in a total magnification of 10×10 = 100×, not 20×.
To achieve a total magnification of 20×, one would need to use a 2× objective lens with a 10× eyepiece lens, or a 10× objective lens with a 2× eyepiece lens. Therefore, the statement that the total magnification achieved using a 10× objective lens with a 10× eyepiece lens is 20× is false.
