three main functions on the skin‚ the first is to prevent colonization by pathogenic strains because they limit the space for other pathogens‚ the second is that they produce vitamins‚ finally‚ it also helps in metabolism. 6) Who does dsRNA interact with Toll Receptor 3 and why is it found in the endosome? (10 pt) Pieces of pathogens (particularly pieces of viruses) do dsRNA interact with TLR-3. Because the pathogens (viruses) are destroyed into pieces in the endosome‚ after they are destroyed‚ they

design. Microorganisms are very diverse and include all the bacteria and archaea and almost all the protozoa. They also include some members of the fungi‚ algae‚ and animals such as rotifers. Many macro animals and plants have juvenile stages which are also microorganisms. Some microbiologists also classify viruses as microorganisms‚ but others consider these as nonliving.[2][3] Most microorganisms are microscopic‚ but there are some bacteria such as Thiomargarita namibiensis[4] and some protozoa such

Bacteria Bacteria are microscopic organisms whose single cells have neither a membrane-enclosed nucleus nor other membrane-enclosed organelles like mitochondria and chloroplasts. Another group of microbes‚ the archaea‚ meet these criteria but are very different from the bacteria in other ways. In fact‚ there is considerable evidence that you are more closely related to the archaea than they are to the bacteria! Bacteria are living things that are neither plants nor animals‚ but belong to a group

bacterial infections. B) mixing a heat-killed pathogenic strain of bacteria with a living nonpathogenic strain can convert some of the living cells into the pathogenic form. C) mixing a heat-killed nonpathogenic strain of bacteria with a living pathogenic strain makes the pathogenic strain nonpathogenic. D) infecting mice with nonpathogenic strains of bacteria makes them resistant to pathogenic strains. E) mice infected with a pathogenic strain of bacteria can spread the infection to other mice.
