Answer:
Emerging properties may arise by transient interactions such as individual organisms building a population. Human interaction in populations leads to the emergence of language, poetry, musical composition, and art. When populations of different species interact, communities form. Many emergent properties are the result of interactions between species in communities.

Answer:
The intracellular molecule produced by the receptor ligand complex is called Second messenger.
Explanation:
Receptors are membrane bound proteins which bind to the ligands which are also called first messengers and cause cellular changes. These intracellular changes are mediated by second messengers such as proliferation, differentiation, migration, apoptosis, transcription, contractions etc. They are specific for specific first messengers such as homones and growth factors. They relay the signals between the ligands to their target molecules in the cytosol or nucleus. Most common second messengers are cAMP, cGMP, DAG, IP3.
Signal amplification by second messenger can be explained by the example of IP3 which cayses the release of Calcium ions from the intracellular stores and cause contractions.
