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.
list and describe the structural components of viruses. - capsid built from capsomeres encloses the viral genome-some viruses have accessory structures to help them infect their hosts-membranous envelope surrounds the capsids of flu viruses-elongated icosahedral capsid heads and protein tail pieces are on t-even phages.xplain how viral infections may cause disease. - some viruses damage or kill cells by triggering the release of hydrolytic enzymes from lysosomes-some viruses cause the infected cell to produce toxins that lead to disease symptoms-other viruses have molecular components, such as envelope proteins, that are toxic.
