What is an Important Source of the Molecular Complexity and Diversity

Question

What is an important source of the molecular complexity and diversity of living matter?
A)The unique properties of water.
B)The variation in carbon skeletons.
C)The non-polar nature of hydrocarbons.
D)The diversity of elements on Earth.
E)Evolution.

Accepted Answer

Carbon is essential to life since it can bond with up to four other atoms, including other carbons, to form a vast array of complex molecules with different shapes and functions. The variation in carbon skeletons contributes to the molecular complexity and diversity of living matter.

Answer: E
 Evolution has driven the diversification of life on Earth, leading to the development of new species, new traits, and new molecular structures. Over time, the process of natural selection has favored those organisms that were better adapted to their environment, leading to an increase in diversity and complexity of living matter.
