Biology
the scientific study of life
We recognize life by
what living things do
Life possesses
order
Life displays
evolutionary adaptation
and
regulatory responses
Living organisms respond to
their environment
Living organisms
grow and develop
Living organisms process
energy
Living organisms reproduce
their own kind
Until well into the 1800’s it was commonly thought that
living
organisms could arise spontaneously from nonliving matter.
The continuity of life is coded in DNA
Shared molecular “alphabet” of four letters (nucleotides)
DNA Neuclotides
A - Adenine T - Thymine
C - Cytosine G - Guanine
Biologists explore life from
microscopic to global scales
molecule, organelle, cells, tissues, organ, community
Emergent properties
are those properties not present in
the components, only in the system.
Emergent properties are due to
the arrangement and
interaction of parts as complexity increases.
Emergent properties are a common theme
in biology and
can be observed at all levels of organization.
