Living organisms are self-replicating,evolving,and self-regulating interactive systems capable of responding to external stimuli. Explain.

(N/A) $\Rightarrow$ Living organisms are self-replicating,evolving,and self-regulating interactive systems capable of responding to external stimuli.
$\Rightarrow$ The unique characteristics of life arise from the interactions among the components of the organism.
$\Rightarrow$ Properties of tissues are not present in the constituent cells but arise as a result of interactions among the constituent cells.
$\Rightarrow$ Similarly,properties of cellular organelles are not present in the molecular constituents of the organelle but arise as a result of interactions among the molecular components comprising the organelle.
$\Rightarrow$ These interactions result in emergent properties at a higher level of organization.
$\Rightarrow$ This phenomenon is true in the hierarchy of organizational complexity at all levels.
$\Rightarrow$ Therefore,we can say that living organisms are self-replicating,evolving,and self-regulating interactive systems capable of responding to external stimuli.
$\Rightarrow$ Biology is the story of life on Earth and the story of evolution of living organisms on Earth.
$\Rightarrow$ All living organisms—present,past,and future—are linked to one another by the sharing of the common genetic material,but to varying degrees.
