INTRODUCTION TO BIOLOGY

November 17, 2018

Biology is a vast field. we cannot explain into one post but there is a little introduction to biology.

Biology is the study of living organisms. The word biology taken from the Greek word, bios means living things and logos means study. This field is divided into many specialized fields.

An organism could be a living entity consisting of cell e.g. bacteria, or many cells e.g. animals, plants and fungi.

Aspects of bioscience vary from the study of molecular mechanisms in cells to the classification and behaviour of organisms, however, species evolve and interaction between ecosystems.

Biology typically overlaps with different sciences; as an example, biochemistry and toxicology with biology, chemistry, and medicine; biophysics with biology and physics; stratigraphy with biology and geography; astrobiology with biology and astronomy. Social sciences like geography, philosophy, psychology and sociology also can interact with biology, as an example, in the administration of biological resources, developmental biology, biogeography, evolutionary psychology and ethics.

The fields inside biology are additional divided based on the scale at that organisms are studied and therefore the ways wont to study them: biochemistry examines the basic chemistry of life; molecular biology studies the complicated interactions of systems of biological molecules; cellular biology examines the essential 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 however various organisms interrelate.

Applied fields of biology like drugs and genetic analysis involve several specialised sub-disciplines.

A central organizing thought in biology is that life changes and develops through evolution which all lifeforms better-known have a typical origin.

Charles Darwin established evolution as a viable theory by articulating its driving force, natural selection (Alfred Russel Wallace is recognized because the co-discoverer of this concept).

Darwin theorized that species and breeds developed through the processes of natural {selection|survival|survival of the fittest|selection|natural process|natural action|action|activity} in addition as by artificial selection or selective breeding.

Genetic drift was embraced as a further mechanism of biological process development within the modern synthesis of the theory.

Biological kind and performance is formed from and is passed on to future generation by genes, that are the first units of inheritance.

Physiological adaption to an organism’s surroundings can’t be coded into its genes and can’t be transmissible by its offspring.

Remarkably, wide completely different organisms, together with bacterium, plants, animals, and fungi, all share identical basic machinery that copies and transcribes desoxyribonucleic acid into proteins.

For example, bacterium with inserted human desoxyribonucleic acid can properly yield the corresponding human protein.

Here are some biology terms. CheckĀ out this and increase your biology knowledge.
