Which cell part is not found in an amoeba?
-
Nucleus
-
Cell membrane
-
Cell wall
-
Vacuole
Correct Answer
A. Cell wallExplanation
Amoebas are single-celled organisms that belong to the group of protists. Unlike plant cells, amoebas do not possess a cell wall. Instead, they have a flexible and dynamic cell membrane that allows them to change shape and move. The absence of a cell wall in amoebas enables them to engulf and consume food particles by extending their pseudopods. Therefore, the correct answer is cell wall.Rate this question:

A living thing, usually with one cell that has a nucleus and other cell parts, is a
-
Moneran
-
Protist
-
Virus
-
Fungus
Correct Answer
A. ProtistExplanation
A protist is a living thing that can be composed of a single cell with a nucleus and other cell parts. This category includes various organisms such as algae, amoebas, and paramecia. Unlike monerans, which are prokaryotic organisms without a nucleus, protists have a more complex cellular structure. Viruses are not considered living organisms as they lack cellular structure and can only replicate inside host cells. Fungi are also multicellular organisms with a distinct cellular structure, making protist the most suitable answer.Rate this question:

In one stage of its life cycle, the slime mold flows like a(n)
-
Paramecium
-
Diatom
-
Amoeba
-
Euglena
Correct Answer
A. AmoebaExplanation
The correct answer is amoeba because amoebas are known for their ability to move by extending their cytoplasm in a flowing motion, which is similar to the movement of slime molds in one stage of their life cycle. Amoebas use pseudopods to propel themselves forward, allowing them to change direction and navigate their environment. This characteristic makes amoebas a suitable comparison for the movement of slime molds in this particular stage of their life cycle.Rate this question:

Malaria is caused by
-
A virus
-
A bacteria
-
A dinoflagellate
-
A sporozoan
Correct Answer
A. A sporozoanExplanation
Malaria is caused by a sporozoan. Malaria is a parasitic disease that is transmitted to humans through the bite of infected female Anopheles mosquitoes. The parasite responsible for malaria is called Plasmodium, which is a sporozoan. It enters the human bloodstream through the mosquito bite and travels to the liver, where it multiplies and matures. From the liver, it infects red blood cells, leading to the symptoms of malaria. Therefore, the correct answer is a sporozoan.Rate this question:

All animal-like protists are mobile
-
This statement is true
-
This statement is false
Correct Answer
A. This statement is falseExplanation
The statement is false because not all animal-like protists are mobile. While many animal-like protists, such as amoebas and paramecia, are indeed mobile, there are also non-mobile animal-like protists, such as sporozoans. These protists are parasitic and live inside the bodies of other organisms, relying on their hosts for movement. Therefore, it is incorrect to claim that all animal-like protists are mobile.Rate this question:

Which of the following organisms uses cilia to move?
-
Euglena
-
Amoeba
-
Dinoflagellates
-
Paramecium
Correct Answer
A. ParameciumExplanation
Paramecium uses cilia to move. Cilia are hair-like structures that cover the surface of the organism and beat in coordinated waves, allowing it to move through its environment. Euglena uses a whip-like tail called a flagellum to move, while amoeba uses pseudopods or "false feet" to crawl. Dinoflagellates also have flagella for movement. Therefore, out of the given options, paramecium is the only organism that uses cilia for locomotion.Rate this question:

Red tide is caused by
-
Diatoms
-
Green algae
-
Dinoflagellates
-
All of the above
Correct Answer
A. DinoflagellatesExplanation
Red tide is caused by the presence of dinoflagellates. These are single-celled organisms that can produce toxins, leading to the discoloration of water and the formation of a red tide. Dinoflagellates are a type of plankton and are known to undergo population explosions, resulting in the formation of large blooms. These blooms can be harmful to marine life, as the toxins produced by dinoflagellates can be detrimental to fish, shellfish, and other organisms in the water. Therefore, dinoflagellates are the main cause of red tide occurrences.Rate this question:

A _____ is an example of a fungus.
-
Diatom
-
Bacteria
-
Mushroom
-
Euglena
Correct Answer
A. MushroomExplanation
A mushroom is an example of a fungus because mushrooms are the fruiting bodies of certain types of fungi. Fungi are a distinct kingdom of organisms that include mushrooms, yeasts, molds, and other types of fungi. They obtain nutrients by decomposing organic matter and play important roles in ecosystems as decomposers. Mushrooms are specifically the reproductive structures of some fungi, releasing spores that can germinate and grow into new fungal organisms. Therefore, a mushroom is a specific example of a fungus.Rate this question:

Ringworm and athletes foot are caused by
-
Bacteria
-
Viruses
-
Fungi
-
Protists
Correct Answer
A. FungiExplanation
Ringworm and athlete's foot are both common fungal infections. Fungi are microscopic organisms that can invade the skin, hair, and nails, causing various types of infections. Bacteria and viruses are different types of microorganisms that cause different types of infections, but they are not responsible for ringworm or athlete's foot. Protists, on the other hand, are a group of eukaryotic microorganisms that include protozoa and algae, and they are not known to cause ringworm or athlete's foot either. Therefore, the correct answer for the cause of ringworm and athlete's foot is fungi.Rate this question:

Fungi used to make bread and alcohol are
-
Mushrooms
-
Rusts
-
Mildew
-
Yeasts
Correct Answer
A. YeastsExplanation
Yeasts are used to make bread and alcohol because they are a type of fungi that can ferment sugars into alcohol and carbon dioxide through a process called fermentation. In bread-making, yeast is added to the dough to produce carbon dioxide gas, which causes the dough to rise. In alcohol production, yeasts convert the sugars in fruits or grains into alcohol, resulting in the fermentation process that produces beer, wine, and other alcoholic beverages. Mushrooms, rusts, and mildew are different types of fungi that do not have the same ability to ferment sugars and are not commonly used in bread or alcohol production.Rate this question:

Yeasts are an unusual sac-fungus in that they reproduce by___
-
Fission
-
Sexual reproduction
-
Fermentation
-
Budding
Correct Answer
A. BuddingExplanation
Yeasts are an unusual sac-fungus because they reproduce through budding. Budding is a form of asexual reproduction where a small outgrowth or bud forms on the parent cell and eventually separates to become a new individual. This process allows yeasts to rapidly multiply and colonize their surroundings. Unlike fission, which involves the splitting of a parent cell into two equal parts, budding involves the formation of a smaller offspring that gradually grows in size before detaching. Sexual reproduction and fermentation are not the primary methods of reproduction for yeasts.Rate this question:
