*”biology” is the ‘natural science’ that studies ‘life’ + ‘living organisms’ – including their…*

‘physical structure’

‘chemical processes’

‘molecular interactions’

‘physiological mechanisms’

‘development’

‘evolution’

.

.

(despite the complexity of the ‘science’, there are certain ‘unifying concepts’ that consolidate it into a ‘single’ + ‘coherent’ field)

.

(‘biology’ recognizes…)

the ‘cell’ as the basic unit of ‘life’

.

‘genes’ as the basic unit of ‘heredity’

.

‘evolution’ as the ‘engine’ that propels the ‘creation’ + ‘extinction’ of ‘species’

.

(‘living organisms’ are ‘open systems’ that survive by transforming ‘energy’ + decreasing their ‘local entropy’ to maintain a ‘stable’ + ‘vital’ condition defined as ‘homeostasis’)

.

(‘sub-disciplines’ of biology are defined by the ‘research methods’ employed and the kind of ‘system’ studied) –>

(“theoretical biology” uses ‘mathematical methods’ to formulate ‘quantitative models’)

.

(‘experimental biology’ performs ’empirical experiments’ to test the validity of ‘proposed theories’ and understand the mechanisms underlying ‘life’ and how it appeared and evolved from ‘non-living matter’ about ‘4 billion years ago’ through a gradual increase in the complexity of the ‘system’)

(“of the utmost importance…”)

(“do or die”)
