What Is Biology

Do you know what biology is? Biology is a branch of the natural sciences whose function is to study life, seeking to understand the characteristics of a living being, from the most evident aspect commonly shared by different species, to the most intrinsic metabolic activity of an organism.

Therefore, being a very broad and detailed science, it does not take into account only the vital functioning, but also the relations of behaviors and particular habits or together of individuals, whether at any level of organic complexity: viruses, bacteria, protozoa, fungi, plants and animals, active and passive members of the inorganic physicochemical environment (lithosphere, hydrosphere and atmosphere), each subject to the selection and adaptation of its historical time.

This science, officially recognized around 1800, has since used the scientific method to analyze, confirm or refute a statement or explanation, through observations or experiments empirically tested.

ORGANIZATION LEVELS IN BIOLOGY

Molecule – Organelle – Cell – Tissue – Organ – System – Organism – Population – Community – Ecosystem – Biosphere

MAIN SUBDIVISIONS OF BIOLOGY

Anatomy: Comprises the study of the morphological structure from the cell to a system;

Cytology: Studies the cell in all its aspects (shape, size, function, composition and function);

Ecology: Observes the relationships of living beings with each other and inserted in the environment;

Embryology: Examines the formation and development of organisms;

Evolution: Analyzes the supposed events since the formation of the planet and the mechanisms through which organisms passed and still pass, from the genesis of the first living being;

Paleontology: Reconstructs the history of the planet based on fossil records;

Physiology: Studies the functioning of a cellular anatomical unit and its union, composing the tissues and organs, totaling the integrality of the body systems;

Genetics: Research the fascinating chemical nature of hereditary material and its transfer over the generations;

Histology: Analyzes the specificity of organic tissues;

Virology: Study viruses;

Mycology: Studies fungi;

Protistology: Study protozoa;

Botany: Study vegetables;

Zoology: Study animals;

Taxonomy and Systematics: They analyze the phylogenetic characteristics between species, classifying them according to the degree of similarity.
