Protists are very important in biological and economic point of view. * The term “protist” is derived from the Greek protiston, meaning the “first of all ones.” * Individual protists tend to be quite small, either unicellular or an undifferentiated multicellular mass.
With the help of spore-producing protists such as Kneallhazia solenopsae the red fire ant populations can be reduced by 53-100%.  However, it is unclear how frequently sexual reproduction causes genetic exchange between different strains of Plasmodium in nature and most populations of parasitic protists may be clonal lines that rarely exchange g...

Oxford Dictionary of Biology. Martin, E. and Hine, R. (2008).
Many protists live individually, but some are colonial, which means they live in groups of the same species and are attached to each other. The oldest fossils of protists are only about 1.5 billion years old.
He gives as examples the discoveries of Christopher Columbus, Luigi Galvani, Hans Christian Ørsted, Michael Faraday, Claude Bernard, Charles Richet, Louis Pasteur. It was he who introduced the word and the concept of serendipity in the medical scientific world in 1945, with a chapter " Gains from Serendipity ”from The Way of Investigator.
Multicellular organisms evolved from colonies of unicellular protists. Algae are photosynthetic protists whose chloroplasts support food chains in freshwater and marine ecosystems.
As a student who took two AP classes during high school I felt it was a struggle to keep up with my other classes because I was too focused on my AP courses. Debra Shaver, director of admission at Smith College, understands the annoyance that some AP teachers have, but she says that “you may be doing students a disservice by dropping the AP program,...
Microorganisms are often described as unicellular, some unicellular protists are visible to the naked eye, and some multicellular species are microscopic. By improving the microscope and highlighting the existence of bacteria as early as the 17th century, Antoine van Leeuwenhoek appears to be the forerunner of the study of microorganisms and cell bi...
Proterozoic Protists A single-celled eukaryote or protist can carry chlorophyll (it can be an autotrophic, photosynthetic, "alga"), it can eat other organisms (it can be an organotrophic, "protozoan" "animal"), or it may do both. But many amoebalike protists do not have cell walls made of cellulose and so do not preserve well.
The domain Eukarya encompasses all of the kingdoms of eukaryotes. Taxonomists are in the process of sorting out various kingdoms of prokaryotes within the domains Bacteria and Archaea, and also splitting the protists into several kingdoms within the domain Eukarya.
Biology (Raven et al. All living organisms require different nutrients for survival however if heterotrophs or autotrophs lack essential nutrients and cannot obtain these in their diet they will show signs of deficiency and eventually die.

Gregarines are a varied collection of apicomplexan protists that parasitize many invertebrates such as the honey bee, which can endure brief life spans and colony loss (Stejskal 1965). Protists are, as described by the biological encyclopedia “a kingdom of simple eukaryotic organisms, usually composed of a single cell or a colony of similar cells.” ...

The desire to know the differences between organisms is an important event in human history, and medical science would not be where it is today without this discovery. However, some unicellular protists and bacteria are macroscopic and visible to the naked eye.
Ever since the first microscope was invented in 1590, they have improved our knowledge in basic biology and biomedical research, as well as many other things, all of which are important. The first major discovery that used the microscope was made by Robert Hooke, who used his microscope to study various things, including corks.
The difference between the female students in AP courses and those who are not, those students have a different outlook on how they feel regarding being successful. As for the other science levels, there is a slightly higher population of females, which is to be caused by having more male students in the AP courses.
