The way in which one can identify the disease-causing organism if a species of insects are dying from a disease that results in the production of cysts. Introduction: Some of the protists have the ability to produce cysts in harmful conditions. These protists undergo sexual reproduction and release cysts. Cysts are composed of a tough and hard cell wall. The purpose of the cysts is to protect the protist. However, after the unfavorable conditions are over, the cysts grow back into a protist.

Question

Definition Definition Organism that lives in the body of another organism and obtains food at the expense of the host. A parasite can directly or indirect harm the host. There are two kinds of parasites: internal and external. An internal parasite lives inside another organism and is known as an endoparasite. An external parasite lives on the body surface of the host and is known as an ectoparasite. Protozoa and helminths are examples of major human parasites.

Protists are a group of eukaryotic organisms that are brought together by scientists mostly by convenience. I) What is the relationship between all protists that ties them together? ii) provide an example of a autotrophic and heterotrophic protists group, iii) what is the relationship between the multicellular eukaryotes and the protists?

In the early 1930s, G. F. Gause carried out a series of experiments using two species of ciliated protists (Paramecium), which are single-celled eukaryotic protozoans. The protists were cultured together and separately, with the bacteria being the single food source. The results are shown in the figure below. (a) Based on figure, identify and explain the interaction that is taking place between P. caudatum and P. aurelia. (b) Clam shrimp, a natural predator to P. caudatum, is introduced to the culture containing both P. caudatum and P. aurelia after 24 days. Predict the impact that the clam shrimp will have on the culture and the populations. Justify your prediction.

A) A major difference between eukaryotic cells and prokaryotic cells is that eukaryotic cells Group of answer choices exhibit little if any compartmentalization of function are generally smaller than prokaryotic cells have a large degree of internal organization lack organelles have little if any internal organization B) Which of the following statements about protists is false? Group of answer choices Some protists are mixotrophic Certain protists share a common ancestor with land plants Some protists are photosynthetic prokaryotes which are similar to the ancestral chloroplast Protists are a polyphyletic group of organisms that often bear little resemblance to each other Although most protists are unicellular, some protists are multicellular as well
