1. Enterococcus and coliforms can enter the water through feces. Although a water sample is negative for these bacteria, it could still be infected by pathogens from other sources than feces.
2. Culture media are sterilized by filtration because they could contain antibiotics or serum which deteriorate upon heat. Filtration is used in sanitation to remove large particles.
3. In the membrane filter technique, it is assumed that <span>all viable bacteria will form colonies. This means that formed colonies develop from the viable bacteria so that the number of colonies suggests the number of bacteria.
4. E. coli is negative for Citrate and Voges-Proskauer tests, and is positive for Indole and Methyl red tests.
5. The answer is yes because eo</span><span>sin-methylene blue agar is inhibitory to Gram+ bacteria.</span>
The mRNA base arrangement shaped amid the translation utilizing the DNA grouping appeared above label feline ggc at is TAG CAT and GGC would combine with UTC GTU and TTG.
The single mRNA atom is blended as a constant strand. The other contrast between the two procedures is that amid DNA union the whole chromosome is replicated. Amid translation, particular qualities are deciphered in light of signs, for example, interpretation elements.
The awnser is true!! I hope this helped!
