In simple diffusion, molecules move from an area of
The Correct Answer is {"dropdown-group-1":"B","dropdown-group-2":"B"}
Choice A rationale: Low, high is incorrect because it is the opposite of the direction of simple diffusion. Simple diffusion is the passive movement of molecules along their concentration gradient, which means from high to low concentration.
Choice B rationale: Low, equal is incorrect because it is not the final state of simple diffusion. Simple diffusion will continue until the concentration of molecules is equal on both sides of the membrane.
Choice C rationale: Equal, low is incorrect because it is not possible for simple diffusion. Simple diffusion will stop when the concentration of molecules is equal on both sides of the membrane, and there will be no net movement of molecules.
Choice D rationale: Equal, high is incorrect because it is not possible for simple diffusion. Simple diffusion will stop when the concentration of molecules is equal on both sides of the membrane, and there will be no net movement of molecules.
Choice E rationale: High, low is correct because it is the definition of simple diffusion. Simple diffusion is the passive movement of molecules along their concentration gradient, which means from high to low concentration.

Correct Answer is C
Explanation
Choice A rationale: Eukaryotes is incorrect because eukaryotes are organisms that have cells with a nucleus and other membrane-bound organelles, such as animals, plants, fungi, and protists. Some eukaryotes, such as protists, are microscopic and require microscopy to be studied, but others, such as animals and plants, are macroscopic and can be seen with the naked eye.
Choice B rationale: Fungi is incorrect because fungi are a group of eukaryotic organisms that include mushrooms, molds, yeasts, and lichens. Some fungi, such as yeasts and molds, are microscopic and require microscopy to be studied, but others, such as mushrooms and lichens, are macroscopic and can be seen with the naked eye.
Choice C rationale: Prokaryotes is correct because prokaryotes are organisms that have cells without a nucleus or other membrane-bound organelles, such as bacteria and archaea. All prokaryotes are microscopic and require microscopy to be studied. Prokaryotes are the smallest and most abundant living organisms on Earth.
Choice D rationale: Plants is incorrect because plants are a group of eukaryotic organisms that have cells with a cell wall, chloroplasts, and a large central vacuole, such as mosses, ferns, and flowering plants. Some plants, such as mosses and algae, are microscopic and require microscopy to be studied, but others, such as ferns and flowering plants, are macroscopic and can be seen with the naked eye.
Correct Answer is ["A","B","E","F"]
Explanation
Choice A rationale: Transfer pipette is correct because you need a transfer pipette to transfer a drop of water or a liquid specimen onto the center of the slide. A transfer pipette is a plastic or glass tube with a bulb at one end that can suck up and release liquids.
Choice B rationale: Clean slide is correct because you need a clean slide to place the specimen on. A slide is a thin, flat piece of glass or plastic that can be viewed under a microscope. A clean slide ensures that there is no contamination or interference from other substances.
Choice C rationale: Bunsen burner is incorrect because you do not need a Bunsen burner to make a wet mount. A Bunsen burner is a device that produces a flame by mixing gas and air. A Bunsen burner is used for heating, sterilizing, or burning substances, not for making a wet mount.
Choice D rationale: Timer is incorrect because you do not need a timer to make a wet mount. A timer is a device that measures or indicates the passage of time. A timer is used for timing experiments, not for making a wet mount.
Choice E rationale: Tweezers is correct because you need tweezers to pick up and place the specimen on the slide. Tweezers are a pair of metal or plastic pincers that can grasp and hold small objects. Tweezers are useful for handling delicate or microscopic specimens.
Choice F rationale: Cover slip is correct because you need a cover slip to cover the specimen on the slide. 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.
