Triops longicaudatus, a crustacean often referred to as a type of tadpole shrimp, is found in various freshwater bodies, especially temporary pools, in North America, South America, the Caribbean, Japan and some Pacific Islands.
At the very least, all viruses contain two components: the capsid (a protein shell), and a genome, consisting of either DNA or RNA. Some viruses also include accessory proteins to aid in infection, or a lipid bilayer to further protect their contents from the environment.atellite viruses are some of the smallest possible reproducing units in nature; they achieve this by relying on both the host cell and a host virus (in this case, TMV) for the machinery necessary for them to reproduce.
Viruses are even simpler than bacteria cells. The basic of structure of all viruses is similar. Viruses have a core of nucleic acid surrounded by a protein coat. At their core, all viruses contain either DNA or RNA.Unlike animal and plant cells, viruses do not contain both nucleic acid. The Capsid is the DNA or RNA core of a virus that is surrounded by a protein coat.The capsid protects the nucleic acid. Besides a Capsid, some viruses, especially animal viruses, are covered with another protective coating called an Envelope.iruses are even simpler than bacteria cells.
