The term inert may also be applied in a relative sense. For example, molecular nitrogen is an inert gas under ordinary conditions, existing as diatomic molecules, N 2. The presence of a strong triple covalent bond in the N 2 molecule renders it unreactive under normal circumstances.
The noble gases helium, neon, argon, krypton, xenon are nonreactive and have no known direct biological role — albeit xenon nevertheless very surprisingly exhibits both anesthetic and neuroprotective side-effects despite usually being considered "chemically inert," and can activate at least one human transcription factor. (Radon is ...
Inert gas; Noble gas, historically called inert gas; Inert knowledge, information which one can express but not use; Inert ingredient, a component of the excipient of a pharmaceutical drug; Inert munition, a round that does not contain any energetic material; Inert prime, a type of behaviour of a prime under an algebraic extension
In biology, a substrate is the surface on which an organism (such as a plant, fungus, or animal) lives.A substrate can include biotic or abiotic materials and animals. For example, encrusting algae that lives on a rock (its substrate) can be itself a substrate for an animal that lives on top of the algae.
Fibrous proteins are structural or storage proteins that are typically inert and water-insoluble. A fibrous protein occurs as an aggregate due to hydrophobic side chains that protrude from the molecule. A fibrous protein's peptide sequence often has limited residues with repeats; these can form unusual secondary structures, such as a collagen ...
Quantum biology – The field of quantum biology applies quantum mechanics to biological objects and problems. Decohered isomers to yield time-dependent base substitutions. These studies imply applications in quantum computing. Agronomy and agriculture; Many biophysical techniques are unique to this field. Research efforts in biophysics are ...
Inert gas continues to be taken up until the gas dissolved in the tissues is in a state of equilibrium with the gas in the lungs (see: "Saturation diving"), or the ambient pressure is reduced until the inert gases dissolved in the tissues are at a higher concentration than the equilibrium state, and start diffusing out again.

Biology uses essentially 20 amino acids for its coded protein enzymes, representing a very small subset of the structurally possible products. Since life tends to use whatever is available, an explanation is needed for why the set used is so small. [ 120 ]
