The chemical tags that are attached to DNA, known as the epigenome, can potentially be altered by the environment. These tags change the amount of protein that is produced from the genes by making them more or less active.
- Traits are frequently influenced by environmental factors rather than genetics. Although not always. Sometimes a gene's DNA sequence or degree of activity is altered by the environment.
- The proteins that a gene produces can be replaced by either of these effects, which in turn impacts characteristics.
- The nucleotide sequence of a gene may alter as a result of some harmful environmental influences. DNA strands, for instance, can be damaged by UV light.
- Certain pollutants, such as those found in plastic and cigarette smoke, can change how DNA bases behave chemically, allowing one DNA base to stand in for another.

Explanation:
The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.

<h2>Respiratory Acidosis</h2>
Explanation:
- <em><u>The need for a stronger than normal stimulus in order to trigger an action potential</u></em>
- The reasons for impaired respiration include aviation route obstacle, discouragement of the respiratory focus in the<em> brain stem, lung disease, and medication overdose</em>
- The <em>hypoventilation </em>brings about raised c<em>arbon dioxide levels in the blood, the H levels increment, and the pH estimation of the blood decreases</em>
- Respiratory acidosis is a health related crisis in which diminishes the <em>blood's pH</em> (a condition by and large called acidosis) and the ventilation increases the <em>concentration of carbon dioxide in the blood</em>
Answer:
B. hydrogen compound
Explanation:
Nucleic acids belong in a hydrogen compound.
Nucleic acids should only be placed in that group because of the amount of harm or impact it doers.
