Biology

Biology is an ancient science from the viewpoint in its infancy, but youth from the viewpoint of the current discoveries. The complexity of living matter makes it clear with the discovery of the electron microscope has left and examination of various tissues from living being.

As Science Biology displayed in Greece Soft his first experimental physiology study foundation basicamente nerves in animals and glass, the same way as the human anatomy with the carcasses of monkeys and pigs, is this idea of parallelism between these animals and humans, causing errors in their Conclusions. 

In the XVI century, begin detailed studies of all living things happen. Vesalio study the structure and function of organs from animals, especially humans. It is noted that confidence in the earlier works was limited, centered in personal experience. 

In the XVII century microscope is discovered and biology examines an important advance. Malpighi and Leuwenhoek examine the structure of the weaver respected bacterium, protozoon and semen. 

In XIX century, also made in other departments leads to a second pulse fortress, biology, primarily at the level of molecular biology. 

From etymology viewpoint Biology means the study of life, studying these tables can take the living creatures, their structure, function, reproduction, growth, organization and relations with the resources that surround them. 

They are disciplines of Biology: the botany, the study of plants, Taxonomy, classification of living creatures, zoology, the study of animal anatomy, examination of the structure of living beings, physiology, study of how the living entity; Embryology, the study of evolution embryo, Genetics, Ecology, Evolution ... Relations with the resources that surround them. 

Scientific method: 

The source of a scientific fact is in strict adherence to the facts that we checked. The scientific discoveries to be made public, but with validity requires rigor of the study and reliability of the results. 

The purpose of science is: 

a) Find the correlation between the observed phenomenon and the causes that produce them. 

b) General principles, which allows for effects and other 

This is necessary to do so with appropriate and using a method Scientific. The scientific method part of a work hypothesis that based on the results obtained can be changed or no. Hypothesis much more credible, will only be verified, but it can not fall into the mistake to regard it as an absolute truth, at least, can the hypotheses theories. 

Webster defines theory as: general principle offered to verify the phenomena. A theory can predict new scientific facts or new relations between phenomena and have to be exposed to the cope and generalized form (Einstein). 

An incorrect theory creates contradictions and are the same error message that two or more different theories can explain a similar phenomenon. 

One of the goals to achieve, is to provide a causal explanation of the system used for the different methods, such as the agreement with the differential method. The statistics are important for success in an investigation. 

Nomenclature and biological entities: 

To achieve greater precision possible and to have an internationally acceptable system is the custom to use Latin or Greek terms to identify the species and new discoveries. 

The accepted units more, Micron, which is part of thousandths of a millimeter, and the Amgstron it would be 1 mm = 100,000,000 for this as regards the length units in terms of weight units are micrograms of equivalence of diplomas 1 1000000 .. = MCR, nanogramo 1 GR. = 1000000000 and pictogram 1 GR. = 1000000000000, even in biology the Dalton used when Dalton is the weight of the hydrogen atom (one water molecule Dalton would be 18).
