<span>Accommodation is the ability in which the eye changes its focus from viewing distant objects and then near objects and vice-versa.
The optics and the focal length of the eye are adjusted such that the focus of the retina is on the object even if the distance varies from the eye. It is like a reflux which can be controlled consciously. The process is a consequence of the changes in the zonal tension which is induced by the contractions of the ciliary muscles.
According to the Helmholtz theory of mechanism, the ciliary muscles that are arranged circularly in the eye relax while viewing a far object. This causes the suspensory ligaments and lens zonules to pull the lens, which flattens it.
When a near object is being viewed, the ciliary muscles contract and loosen up the lens zonules causing the lens to form a thick convex.</span>
Answer:
Responding to stimuli / the environment
Explanation:
A chromosome is a packaged and organized structure containing most of the DNA of a living organism. Messenger RNA is a large family of RNA molecules that convey genetic information from DNA to the ribosome, where they specify the amino acid sequence of the protein products of gene expression. Proteins are large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues.

Explanation:
Phosphorylation is the process of adding a phosphate group to an existing molecule to prepare it to change or do work. ... In glycolysis, in which enzymes breakdown glucose releasing energy, an enzyme called hexokinase helps to transfer one inorganic phosphate group from ATP to glucose to form G6P.
