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.
The second one because the parent and daughter cells are the same
Extremophiles such as halophiles and extreme thermophiles are archeas which live in and can survive in extreme conditions.
Halophiles thrive in high salt concentrations, while extreme thermophiles are used to temperatures like in hot springs (so, very high).

traditional circulatory endpoints of resuscitation in shock include hypertension,tachycardia,decreased mentation and urine output
