What does an amoeba form when it surrounds food?
Certain chemical gradients began to form microtubule sub-units together that extend out on two places on the amoeba's membrane into what are called pseudopodia. These pseudopodia engulf the food and the ameoba pull itself toward the food rather than pulling the pseudopodia into the main body.
What would happen to the paramecium if it did not have a contractile vacuole?
The paramecium would have difficulty regulating its water balance, leading to swelling and potential bursting from an influx of water. Without a contractile vacuole, the paramecium would struggle to expel excess water and maintain osmotic balance, ultimately leading to cell damage or death.
Protozoa are single-celled organisms that can be either heterotrophic or autotrophic. Heterotrophic protozoa feed on organic matter like bacteria, algae, and other small organisms. Autotrophic protozoa produce their own food through photosynthesis, using sunlight to generate energy.
How did Gause's experiment with paramecium demonstrate competitive exclusion?
Gause's laboratory experiment demonstrated the process of competitive exclusion because he was able to isolate the two species and their common limiting resource (food) in the laboratory.

What form of plasmodium produces merozoites?
The form of Plasmodium that produces merozoites is the sporozoite. Sporozoites are the infective form that is transmitted to humans through the bite of an infected mosquito. Once inside the human host, sporozoites develop into merozoites, which are responsible for invading and multiplying within red blood cells.
How does Trichomoniasis develop?
Trichomoniasis is caused by the parasite Trichomonas vaginalis, which is typically spread through sexual contact. Once the parasite enters the body, it infects the genital and urinary tract, leading to symptoms such as vaginal discharge, itching, and pain during urination. If left untreated, trichomoniasis can lead to complications such as increased risk of acquiring other sexually transmitted infections.
How many nuclei does a paramecium have?
"The paramecium has two nuclei, a big and small one. The big one operates as the director of the cell's activities, rather like a little brain. The smaller one is used for reproduction."

What food contains tyrosinase?
I looked it up at Answers.com (http://www.answers.com/tyrosinase?cat=health) Appears that TYROSINASE is contained in some fruits and vegetables (like apples, or potatoes; the entry in Answers.com also explains that this enzyme is responsible for the dark colour produced when cut raw food is exposed to air.
