The answer is commensalism.
The complete answer is: The ecological relationship between organisms where one benefits and the other is not affected is commensalism.
There are four kind of ecological relationships between two organisms: mutualism, amensalism, parasitism, commensalism.
In mutualism the two organisms benefit from each other.
In amensalism one organism in unnafected and the other is harmed.
In parasitism one organism is benefited ant the other harmed.
Explanation:
Objective lenses are responsible for the primary image formation in microscopes, they are the closest part to the object, it defines the image's quality and they determine the magnification and resolution. In an optical microscope you can usually find 3 or 4 objectives (4x, 10x, 40x and 100x) but other configurations and magnifications are possible, in the image I added you can see that.
<em>To determine which objective you will use you need to consider your specimen's size and what are the smallest features in it, NA (numerical aperture) must be considered as well, this is the ability to gather light and it determines depth of focus (how much you can focus without change in the image's sharpness), brightness and resolution (smallest distance between two objects). You'll also need to identify your observation method (phase contrast, darkfield, fluorescence, etc) and in what medium is your sample.</em>
I hope you find this information useful and interesting! Good luck!
An example of a hypothesis leading to a new experiment is this: GALILEO HAD THE IDEA THAT OBJECTS OF DIFFERENT WEIGHT WILL FALL AT THE SAME SPEED. HE TESTED THIS BY DROPPING DIFFERENT BALLS OFF OF THE LEANING TOWER OF PISA.
A scientific hypothesis refers to a proposed explanation, which is made on the basis of limited evidence as a starting point for further investigations. A scientific hypothesis must be tested in order to determine whether it is true or not. Galileo had an idea that objects will different weights will fall at the same rate and he tested the hypothesis by dropping different weights from a height. By doing this, he found out that the hypothesis is right.
The otorhinolaryngologist (or your ear-nose-throat, ENT specialist), will be able to isolate a cause such as abnormalities in muscle contraction, blood vessels or the middle ear. Tinnitus Peritonsillar abscess is commonly encountered clinical entities presenting in everyday practice of otorhinolaryngologist .
