Question
Chapter 28, Problem 1COQ
Summary Introduction
To explain: 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.

Students have asked these similar questions
a salt water protist is placed in fresh water. Which of the following events would most likely occur?
a.) the cell would shrink
b.) the cell would remain the same (no change in shape)
c.) the cell would start to cry
d.) the cell would swell
e.) an increase in the action of its cilia
Which of the following characteristics is NOT one all protists share?
A.
mixotrophic, autotrophic and heterotrophic
B.
eukaryotic
C.

In test tube 3, you detect the presence of substantial amounts of silica.
