The oil immersion objective is necessary to determine the morphology of prokaryotes

2 answers:

6 0

To clearly view the morphology of the prokaryotes, one needs a microscope with higher resolution i.e magnification of ×100. Use of oil for this purpose is important because it reduces the refraction of light as it travels from air to glass. this process increases the resolution of the microscope making it possible to view morphology of bacteria.

This is very true.
Prokaryotes are microorganisms and come in different shapes that would not be visible and recognizable to the normal human eyes by any means but with the oil immersion objective, The oil immersion objective enable a person to be able to view these bacterias at a size that is 1000 times the apparent size of the prokaryotes.

According to the competitive exclusion principle, two species cannot continue to occupy the same A) habitat. B) niche. C) territ

levacccp [35]

Answer:

Niche

Explanation:

Niche basically is the lifelihood of a species that involves feeding on what, drinking from what....

If both species are competing for the same resources, they would compete until a certain species is eradicated. (think of it as 2 species of ants in 2 colonies that are close to each other, take the same leaves, prey and stuff. They would fight with each other in other until one colony is eradicated.) hence, unless a species and adapt and change its niche, both species would fight until one is eliminated. Thus, the principle states that 2 species cannot continue to occupy the same niche, not living environment.
