Answer:
B. So you can always see the entire object at the higher magnification
Explanation:
A microscope is used to view objects smaller than the naked or unaided eyes can see. The objective lens, in conjunction with the occular or eye lens, is used to achieve this purpose. The objective lens are of different magnifications as follows: 10X, 40X, 100X etc.
However, as the magnification increases i.e. higher objective, the object in the field of view becomes smaller and less focused. Hence, the object in the field of view must first be centered at a lower magnification/objective lens before changing to a higher one in order for the entire object to be seen at a higher magnification.

Plasma is the fourth state of matter. Plasma is an ionized gas, a gas into which sufficient energy is provided to free electrons from atoms or molecules and to allow both species, ions and electrons to coexist.
I can conclude about this microbial agent that it is gram-negative. They are bacteria.
<h3>What are gram-negative bacteria?</h3>
Gram-negative bacteria are a group of microbes that have a thin peptidoglycan cell wall.
Conversely, Gram-positive bacteria have a thick peptidoglycan coating, composed of around 30 layers of peptidoglycans.
The gram-negative bacteria include different microbial agents such as <em>Pseudomonas aeruginosa, Chlamydia trachomatis, Escherichia coli, </em>and <em>Yersinia pestis.</em>
