Which statement best explains how arteries and veins help maintain homeostasis?

The carbon dioxide exhaled by the lungs is carried by the veins and arteries to the different parts of the body.
Arteries carry oxygen-rich blood to the different parts of the body, and veins carry carbon dioxide-rich blood to the heart.
Veins carry oxygen-rich blood to the different parts of the body, and arteries carry carbon dioxide-rich blood to the heart.
The oxygen inhaled during respiration is carried around the body through blood by veins and arteries to maintain homeostasis.

Explanation:

the oxygen because all cell produced with oxygen

ans.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
