Answer:
I believe you are asking about the objective lens or eyepiece.
Explanation:
Objective lenses are used to magnify objects enough for you to see them in great detail
Eyepiece/Ocular is what you look through at the top of the microscope.
A tube connects the eyepiece lens to objective lenses, which enhance the magnification power of the eyepiece lens. Both the eyepiece and the objective lens contribute to the magnification of the object.
The eyepiece lens usually magnifies 10x, and a typical objective lens magnifies 40x.

Answer:
Oxygen will dissolve more in H2O at 5 atm and 20 °C than at 5 atm 80 °C
Option B is correct.
Explanation:
Step 1: Data given
Pressure = 5 atm
Temperature = 20 °C or 80 °C
Step 2:
At low pressure, a gas has a low solubility. Decreased pressure allows more gas molecules to be present in the air, with very little being dissolved in solution. At high(er) pressure, a gas has a high solubility.
This means the higher the pressure the more the gas will dissolve. Since The pressure stays constant, it depends on the temperature.
The solubility of gases in liquids decreases with increasing temperature.
This means the gas will dissolve more with a lower temperature.
Oxygen will dissolve more in H2O at 5 atm and 20 °C than at 5 atm 80 °C
The *independent* variable is the one that you always can control. However, the dependent variables are not since they **depend** on another.
