An ion. When it loses electons, a positive ion is formed. When it gains electons, a negative ion is formed.
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

Answer:
Essentially there is not an answer. There are two different definitions.
A holoenzyme is an enzyme that needs to be together with a cofactor(s), required for activity.
In some cases, enzymes constituted by several subunits (like DNA polymerase 3) are call holoenzyme as well, because it will only perform correctly when all its subunits are present.
Answer:
What the scientist is doing incorrectly is disposing of a chemical or biological waste in the common sewer.
Explanation:
One of the most important biosecurity measures is the proper disposal of chemical and biological waste. What the shown scientist is doing incorrectly is disposing of potentially harmful substances in a normal sewer.
<h3>What could he do to make their work in the lab safer?
</h3>
The main thing that must be done to maintain a safe laboratory is to perform proper disposal of chemical or biological waste, which must be placed in airtight containers and transported to a location for safe disposal.
- <em>Chemical waste is usually taken to a landfill where it can be neutralized.
</em>
- <em>Biological waste is transported to incinerators for complete disposal.
</em>
<h3>Why is it important to follow these procedures?
</h3>
Following these procedures is important to avoid chemical or biological contamination of both the environment and people.
