Microscopic examination
The analysis of minute organisms, cellular organization of any biological structure, and composition of body fluids with the help of a microscope is known as microscopic examination. The magnification of specimens or samples under study helps in attaining a clearer picture of it.
Gram Staining
Named after Hans Christian Gram, a Danish bacteriologist, Gram stain is one of the most powerful staining techniques within microbiology. This technique was introduced in 1882 to identify pneumonia-causing organisms. The Gram staining technique uses crystal violet or methylene blue as primary staining colors to distinguish gram-positive from gram-negative organisms. Under a microscope, the gram-positive organisms appear purple-brown, retaining the primary color. Gram-negative organisms appear pink or red as they do not acquire the color of the primary stain.
Explain how science is distinguish from other way of seeking understandings of life?
Life can be defined in various aspects by persons according to their discipline or subject or according to belief such as spiritual, social, or other beliefs. Life can be associated with many terms such as soul, earth, existence, and biology. In the biological aspect, life is the character of an organism by which it can be distinguished from other objects that do not render biological processes such as self-sustaining and signaling. It also distinguishes them from the organism that is dead as they also do not perform biological processes.
