When using high power the diameter of the field of view would be 20 mm.
A microscope is an optical device that is used to view images that cant be seen with the naked human eyes.
It is made up of lens in which the diameter field of view can be determined.
The diameter of the viewed field in an optical microscope is termed the field number and represents the diameter of the field measured in millimeters (mm) at the intermediate image plane.
From the question, there are two types of field of view
- <u>Low-power field of view</u>: which is 2 millieters(mm) and
- <u>High power field of view</u>: which is 10 × low-power field of view
Therefore, to determine the diameter of the field of view when using high power is
10 × 2 = 20mm

Explanation: helminths are parasitic worms that inhabits the intestinal tract of humans; they live within the host and have attachment organs which enable them to reside within their host; examples include: roundworms (Nematodes), tapeworms ( Cestodes) and flukes( Trematodes)
The correct option is C, THAT IS, OZONE.
CFC acts as catalyst, which enable oxygen to react rapidly with ozone, leading to the destruction of the ozone layers. The whole process is a series of free radical reactions that occur in five stages. A single molecule of CFC can destroy as much as 100,000 ozone molecules. Depletion of ozone layers has grave consequences such as skin cancers, eye damages, etc.
The answer is 9 amino acids.
