i) It is a blood vessel having a thick wall.
ii) It carries blood from the heart to different parts of the body.
iii) On regulatory demand of the body it can dilate or constrict.
iv) It doesn't contain any valve.
v) All arteries carry oxygenated blood except the pulmonary artery.
2)Vein ---
i) It is a blood vessel having a thin wall.
ii) It brings blood from different parts to the heart.
iii) It can't dilate or constrict under normal conditions.

Answer:
C) reductionism
Explanation:
The approach of reductionism is applied to decipher the basic concepts that rule some complex life processes. In this approach, the complex life processes can be interpreted by explaining the physical and chemical structure of involved components and their interactions. DNA molecules store genetic information. Inheritance means the transfer of genetic traits from one generation to the next. Therefore, the chemical structure of DNA is the application of reductionism to understand the chemical basis of inheritance.
