Same of Biology..

The biology refers to a Life Science, is the study of life.

With the biology we can examine the structure, function, growth of living bains.


Are different tipes of Biology studys:

Zoology, the study of animals; and microbiology, the study of microorganisms. The fields within biology are further divided based on the scale at which organisms are studied and the methods used to study them: biochemistry examines the fundamental chemistry of life; molecular biology studies the complex interactions of systems of biological molecules; cellullar biology examines the basic building block of all life, the cell; physiology examines the physical and chemical functions of the tissues and organ systems of an organism; and ecology examines how various organisms and their environment interrelate.



Moderns biology and its theories:


Cell theory. All living organisms are made of at least one cell, the basic unit of function in all organisms. In addition, the core mechanisms and chemistry of all cells in all organisms are similar, and cells emerge only from preexisting cells that multiply through cell division.


Evolution. Through natural selection and genetic drift, a population's inherited traits change from generation to generation.


Gene theory. A living organism's traits are encoded in DNA, the fundamental component of genes. In addition, traits are passed on from one generation to the next by way of these genes.

All information flows from the genotype to the phenotype, the observable physical or biochemical characteristics of the organism.



Important Biologist:

Charles Darwin, is the creater of the theory of Natural Selection.
Alexander von Humboldt, investigated the interaction between organisms and their environment.
Thomas Hunt Morgan and his students, and by the 1930s the combination of population genetics.
Watson and Crick, proposed the structure of DNA...
