Answer 2

In biology Regeneration is the process of restoration or new growth by an organism of organs, tissues, etc that have been lost, removed or injured.

Complex organism cannot regenerate because
Regeneration happens through mitosis and a particular type of tissue can give rise to its own kind only. In complex organisms, different tissues and organs have altogether different structures. Regenerating a different kind of tissue from another kind is not possible. Hence, complex organisms are unable to give rise to new individuals through regeneration.
