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.

Answer:
Veins are blood vessels in humans, and most other animals that carry blood towards the heart. Most veins carry deoxygenated blood from the tissues back to the heart; exceptions are the pulmonary and umbilical veins, both of which carry oxygenated blood to the heart. In contrast to veins, arteries carry blood away from the heart.

The study of relationships and the evolutionary history of various groupings of species is known as phylogeny. The goal of phylogeny is to reconstruct the evolutionary course of all species on Earth. A phylogenetic tree also learned as a cladogram, is a schematic diagram used to show the alleged evolutionary relationships between taxa. Diagrams of phylogenetic trees are based on cladistics, or phylogenetic systematics, hypotheses.
Organization of life, according to taxonomy, divides creatures into three domains:
The Eukarya domain are the most easy because they are large enough for their morphological features to be easily seen.
