Anton van Leeuwenhoek, using the microscope, was the first to observe bacteria and protozoa.
Biologists who work in the fields of genomics and molecular biology study DNA genome content and analyze genetics on a molecular level. They do it to map DNA and use it to prevent diseases or anything similar.
No gram stain cannot be used because influenza virus causes flu and virus has no cell wall which we could stain.
Further explanation
Microbial size
A reasonable standard for estimating organisms is the micrometer which is multiple times littler than a meter (one-millionth of a meter). There are 106 µmeters in one meter, and it is these units that are utilized to quantify the size of microscopic organisms. Normally, microscopic organisms extend from around 1 µm to around 5 µm.
Microbial shape
There are a huge number of microbes, yet every one of them are essentially of three unique shapes. Some are rod like and called bacilli and E. coli is rod shaped. While some are round in shape like cocci e.g Staphylococcus. Third type is spiral like and is called spirilla.
Motility of microbes
The have the ability to swim or crawl frequently and interact with their physical and chemical environments.
Spore staining
It is a technique which is used for differentiation and we dye the cell wall and spores of bacteria.
Simple stain
It is one of very simple methods which involves only a single solution for staining.
Hanging drop slide
It is a technique which used wet mount and organism is dipped in it and then that organism is placed on a slide under microscope for analysis.
Gram stain
In this technique in which an organism is stained. It may be gram positive or gram negative.

Intercostal Muscles
The muscles of respiration
are muscles that contribute to exhalation and inhalation by causing the contraction
and expansion of the thoracic cavity. However, diaphragm is the main muscle of breathing
while intercostal muscles is one of the most important muscles for respiration.
Intercostal muscles function by manipulating the width of the rib cage and they
are attached between the ribs.
D, A specialized fatty tissue that does not respond to diet or exercise
