In the field of anatomy, fixation is the preservation of biological tissues from decay due to autolysis or putrefaction. It terminates any ongoing biochemical reactions and may also increase the treated tissues’ mechanical strength or stability.Click to see full answer. Keeping this in view, what does fixation mean?Definition of fixation. : the act, process, or result of fixing, fixating, or becoming fixated: such as. a : a persistent concentration of libidinal energies upon objects characteristic of psychosexual stages of development preceding the genital stage. b : stereotyped behavior (as in response to frustration)Also, what is biological fixation? Biological fixation is the process of converting atmospheric nitrogen into the nitrogenous compounds which plants require. This process occurs in the presence of the bacteria associated with the plants. Examples include Azotobacter, Rhizobacterium, Anabena, etc. One may also ask, what is the purpose of fixation? The aim of fixation is to preserve cells or tissues in as near a life like condition as possible, prevent autolysis and putrefaction, and protect the tissue from subsequent processing. Fixatives have different actions e.g. crosslinking, precipitative, coagulative etc.What is nitrogen fixation simple definition?From Wikipedia, the free encyclopedia. Nitrogen fixation is the process by which nitrogen is taken from its stable gas form (N2) in air and changes into other nitrogen compounds (such as ammonia, nitrate and nitrogen dioxide) useful for other chemical processes. It is an important part of the nitrogen cycle.
