In simple terms, there are 4 categories of protists in basic biology characterized by their type of locomotion.
Locomotion by pseudopods or "false feet" is characteristic of ameobas (i.e. <em>Entamoeba histolytica</em>). Locomotion by papillary projections from the cell membrane called "cilia" is characteristic of <em>Paramecium </em>species. Locomotion by whip-like structures that propel the organism called "flagella" is characteristic of <em>Euglena </em>species.

Lastly, protists that do not have locomotive organelles are exemplified by <em>Plasmodium </em>species, the etiologic agent of malaria.

Mercaptoethanol is the chemical compound with the formula HOCH2CH2SH. ME , as it is commonly abbreviated, is used to reduce disulfide bonds and can act as a biological antioxidant by scavenging hydroxyl radicals (amongst others). It is widely used because the hydroxyl group confers solubility in water and lowers the volatility. Due to its diminished vapor pressure, its odor, while unpleasant, is less objectionable than related thiols.
Stars Like the Sun. When the core runs out of hydrogen fuel, it will contract under the weight of gravity. ... The upper layers will expand and eject material that will collect around the dying star to form a planetary nebula. Finally, the core will cool into a white dwarf and then eventually into a black dwarf.
