B) Due to the high concentration of minerals in water.
C) To facilitate the oxygen-carrying capacity of blood cells.
D) Because water regulates the body's temperature effectively.

Answer 1

Blood contains a significant amount of water because water is a primary solvent for transporting nutrients and other substances throughout the body, regulating internal temperature, and maintaining homeostasis.

Step-by-step explanation:

Blood contains a significant amount of water, largely because water is the primary solvent capable of dissolving numerous substances, which makes it essential for transporting dissolved nutrients throughout the body. Water's ability to dissolve various substances enables it to carry nutrients, gases like oxygen and carbon dioxide, and wastes in a dissolved form, ensuring efficient distribution within the body's cardiovascular system. Furthermore, water comprises about 70% of an adult's body mass, playing a crucial role in regulating internal temperature and maintaining homeostasis, while also cushioning and protecting body structures.

The extracellular matrix of blood, known as plasma, suspends the formed elements such as red blood cells, white blood cells, and platelets, allowing them to circulate and perform their vital functions. Thus, water's presence in blood is vital not only for transporting substances but also for preserving overall health and facilitating numerous physiological processes.
