Answer:

<em>evolution</em>

Explanation:

The theory of common descent states that every organism on the Earth came from a common ancestor in the past. The organisms which are more closely related have a common ancestor in the near past. Through evolution, the ancestors give rise to different species based on their adaptations. However, many genetic similarities can be seen in these organisms which tell that they might have had a common ancestor in the past.

The words that fill in the blanks in order are;

  • atoms
  • Electrons
  • shells
  • Valence electrons
  • Electron distribution
  • Molecules
  • Basic atoms
  • Charge distribution
  • Interact with other molecules electron
  • Harm living organisms

Atoms are composed of electrons. These electrons are arranged in shells. The number of valence electrons (outermost shell electrons) determine the kind of bonds that can be formed in a molecule.

In a molecule, charges are distributed in a unique way and the charge distribution in a molecule determines how the molecule interacts with other molecules. Different molecules can be made by arranging the same basic atoms in different ways.

Harmful substances can be formed when atoms of elements combine in new ways in the environment.
