The general surface of the sin can be viewed through a hand-held stereo microscope. Bacteria are very hard to observe without staining as they are colorless and transparent and tiny in size. The shape, size, and arrangement of fibers in skeletal muscle vary according to the position of the muscle in the body. An infectious disease, also known as a transmissible disease or communicable disease, is an illness resulting from an infection.. Under the microscope at the magnification of 40X, bundles of muscle fibers termed fascicles are seen where each of such bundles are separated by connective tissue, perimysium. Sperms are highly motile and thus require a large amount of energy which is provided by a large number of mitochondria present in the cell. Anthrax is an infection by bacteria, Bacillus anthracis, usually transmitted from animals. The structure of an atom is visible with these microscopes. Image Source: https://doi.org/10.24897/acn.64.68.503. Spirilla is a name given to the spiral-shaped variety, and cocci is the name for sphere-shaped bacteria. Under a light microscope - you will see nothing special, maybe some discoloration due to scattering. Blood is the liquid connective tissue in animals that transfers nutrition, water, oxygen, and carbon dioxide to different parts of the body. Figure: Volvox under the microscope.

Bacteria from the genus Bacillus are primarily found in soil and water, and the most well-known example is E. coli (Escherichia coli).Like cocci, they can be identified by arrangement: single cells (bacillus), pairs (diplobacilli) and chains (streptobacilli). The nucleus of the cells is visible towards the base of the cells. Particles that are translucent and shiny usually have a higher ratio of quartz. In addition, different patterns can be seen on the surface, which is different in different flakes. The shape and size of some algae might change throughout their life, depending on the stage of life and habitat. Some dinoflagellates are macroscopic and can be seen even without any microscope.

Figure: Blood under the microscope. Bacteria are unicellular prokaryotes in which the genetic material is not enclosed inside a nuclear membrane. The acrosome and acrosome cap are present together at the top of the head that appear conical in shape. Salt is essential for the living being as it provides the necessary minerals to the body. Algae in the soil are difficult to obtain, so it is better to culture them before observation. The medulla, in turn, is seen either as a long continuous thread or is fragmented or even absent in some hair. Bacillus is Latin for "stick," which describes the rod-like shape of this type of bacteria. Staphylococcus aureus is fairly small, even by bacterial standards. Under the microscope at 40X, a colorless liquid is seen called plasma that occupies about half of the volume of the blood. Every flock, except those maintained under strict pathogen-free environments, has the potential to be infected. Botulism is a rare but serious illness caused by a toxin that attacks the body’s nerves. These cells are formed in the bone marrow through erythropoiesis. Each wing appears to have a network of irregular veins that strengthen the wing. Under the microscope, about 200-50,000 individual cells arranged in the form of a hollow sphere. Because animal cells are transparent and colorless, it is challenging to observe them directly without staining. Only a very small percentage of mosquitoes are actually infected with West Nile virus, and not everyone bitten by an infected mosquito will become sick.
