Towing capacity, sometimes called maximum towing capacity, is the maximum allowable weight that a vehicle can tow. Towing capacity is specified by the vÂ­ehicle manufacturer and can usually be found in the ownerâs manual. Some towing hitchesâ towing capacity exceeds that of certain cars and trucks, but that is because hitches can often fit on many different types of tow vehicles.
Plasmodium, commonly known as the malaria parasite, is a large genus of parasitic protozoa. As with some other genera of clinically important microorganisms, the genus name also yields a common noun; thus species of the genus are known as plasmodia.he parasite is thought to have originated from Dinoflagellates, photosynthetic protozoa. The most common forms of human malaria are caused by Plasmodium falciparum, P. vivax, P. knowlesi, and P. malariae. P. falciparum, common in sub-Saharan Africa, and P. knowlesi, common in Southeast Asia, are especially dangerous.
Plasmids are circular, double-stranded DNA (dsDNA) molecules that are separate from a cellâs chromosomal DNA. These extrachromosomal DNAs, which occur naturally in bacteria, yeast, and some higher eukaryotic cells, exist in a parasitic or symbiotic relationship with their host cell. Plasmids range in size from a few thousand base pairs to more than 100 kilobases (kb). Like the host-cell chromosomal DNA, plasmid DNA is duplicated before every cell division.
