This means that Staphylococcus aureus is more tolerant to salt (NaCl), however, E. coli is sensitive to NaCl concentrations more than 10%. This also means that Staphylococcus has more fluid in its cytoplasm, as compared to E. coli, which enables it to tolerate in high salt concentration. Further, this also indicates the ability of both microbes to grow on different media compositions and have different nutritional requirements.
The answer is A (1) Prokaryotes
Oxygen is the correct answer !
Answer: Natural selection is one of the forces of evolution and the enviroment where the species lives is the selection agent. For example, suppose a mosquitoes population in a environment free from insecticides, in this environment there's a high frequency of non-resistant mosquitoes because the environment is not exerting any pressure on the resistence trait. But when the environment changes and we use a insecticide upon the mosquitoes population, the populations changes because the non-resistant ones die but those resistant survive and beggin to reproduce more effectively. That's natural selection, differences in survival and reproduction between individuals with different phenotypes (traits) and this differences depend of environmental changes.
