Biologically

Biology is a natural science that is concerned with the study of life, its various forms and its function, how these organisms interact with each other and with the surrounding environment. The word biology in Greek is made up of two words: bio (βίος) meaning life. And loggia (-λογία) means science or study. Biology: the similarity of vegetation and animal cover on the edges of the African and American states, and the existence of the same fossil.

Branches of biology
Biology is an ancient science thousands of years old and modern biology began in the nineteenth century. This science has multiple branches. Among them are:

Anatomy
Botany
Biochemia
Biogeography
Biofisia

 suspect that everyone who reads these words considers himself or herself to be rational. But all of us probably can think of people whom we
consider to be irrational, or at least to behave irrationally on occasion.
These surmises imply the existence of some concept of rationality in
terms of which such judgments are made, but that does not mean that
we would fi nd it easy to articulate that concept precisely, if asked.
What does it mean to be rational—to reason well and effectively?
How does rationality, broadly conceived, relate to the knowledge one
acquires, the beliefs one forms, the explanations one constructs or appropriates, the judgments and decisions one makes, the values one adopts?
If you fi nd the question of what it means to be rational diffi cult to answer
precisely, you are in good company. Philosophers, among others, have
debated it for many centuries.
A closely related question is: What is the character of human reasoning, and, in particular, does it tend to be rational? The second question presupposes an answer to the fi rst. If we cannot say what rationality
is, or what we intend to mean when we use the word, we cannot hope
to determine whether any particular instance of reasoning or behavior
is rational or not.
