What are model organisms?

In science, the model organism is an organism often used for study and experiments and can be considered a representative example of an organism class or has a particularly interesting or easily examined physiology or psychology. Model organisms are also selected for comfort and quick reproduction. Examples include bacteria Escherichia coli , Nematoda caenorhabditis elegans , fruit flies ( Drosophila Melanogaster ), also "laboratory rat"), Myce ( musculus and musculus) ( mus. 1907) How each organ works in detail and how the disease and mutations affect the body.Model organisms are sometimes thoroughly abused or tortured to dismay for animal rights. Many institutions responded by experimenting on lower model organisms or using computer simulations, if possible, perform more humane experiments and delay experiments about higher model organisms, unless absolutely necessary.

The complexity of the model organism is usually a guide to what is used to study. For example, nematodes are relatively simple multicellular organisms and are often used to study the foundations of physiology, such as the way the brain controls parts of the body. A superlative example is Nematode c. More complex animals such as cats or rats are used forMore complicated studies such as vision studies or fine psychological features.
