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.

Alecsey [184]

Answer:

Explanation:

The spontenous genrration theory states that living organisms can be spwan without descent of similar organisms; so in other words, it is possible for living creatures could arise from nonliving matter such as water. Similarily in 1676 Van Leeuwenhoek discovered tiny organisms living in his cup of water- the first bacteria observed by man. Pasteur's spontenous generation theory came into the limelight after his most noteable experiment in 1859; in which he boiled meat broth in down ward tipped flasks. It is importnat to note that the tip of the flask (the neck) is what prevented particles to fall freely and instead the bent neck allowed air to travel through the flask- if the flask were to be tilted on its side the particles would seep into the broth and create a cloud within the flask. Pastuer further decided to boil the broth to possible create bacietia. Boiling the broth exposed the contents to air vessels which contained a filter to stop the particles from seeping thorugh into the broth.  What Pastueru concurred from his experminet was that flasks with filters and no filters that did not allow the particles to pass into the medium of the flask, were unsucessful with createing bacteria life. Thus, Pasteur found that noithing  grew in the flasks unless they were broke open, disapproving that living organisms could be spotenously generated within the broth, was instead created from outside the inards of the flask- and were created as spores or dust.
