Answer:
Molecule not found in DNA is an amino acid.
Explanation:
DNA is a nucleic acid responsible for containing the genetic information of living beings. The basic structure of DNA consists of:
- <em>A sugar, deoxyribose.
</em>
- <em>Nucleotides, including adenine, guanine, cytosine and thymine.
</em>
- <em>Phosphate groups.
</em>
The information contained in DNA allows the synthesis of proteins necessary for the structure and function of living beings. <u>Amino acids</u><u> are part of proteins, but it is a </u><u>molecule that is not found in DNA</u>.
The correct answer is B. are thinner.
Compared with the walls of the arteries are thinner than the walls of the capillaries.
Capillary is termed as a small blood vessel which is from five to ten micrometers. They are known to be the smallest blood vessels in the body.
They do convey blood between venules and arterioles. Substances which exits from capillaries include glucose, water, and oxygen. In embryonic development, new capillaries are formed through vasculogenesis.
The artery is termed as the blood vessel which takes away blood from the heart to the other parts of the body. Many arteries carry oxygenated blood except umbilical arteries and pulmonary artery which carries deoxygenated blood. Arteries are responsible to deliver nutrients and oxygen to all cells as well as they remove carbon dioxide and waste products.
