Explanation:
Metabolism in eukaryotic cells depends on the endoplasmic reticulum because it transports materials between membrane-bounded organelles within the cell.
In this case, the patient has to be moved into an isolated room or into a private room. Vancomycin resistant-enterococci are said to develop a resistance against vancomycin. Enterococci normally live in our skins and intestines as normal flora, therefore it does not cause any problems. In patients who are immunocompromised, they are more likely to be affected by these organisms which commonly infect the intestines, urinary tract infection and wounds. These bacteria are said the be difficult to treat with since there are lesser antibiotics who have greater strength compared to vancomycin.
The answer is cell division
The effect of geographic isolation is that the two populations are subjected to different selection (pressures) and geographic conditions. The conditions in the two areas, if different, will produce different alleles in that species and will be selected for, where genetic differences will gradually accumulate between the two different populations.
In time, enough genetic differences will occur so that the two populations will no longer interbreed. Then, by definition, they have become different species.
