Verified step by step guidance

Step 1: Begin by understanding the composition of whole blood. Whole blood is a specialized connective tissue that consists of two main components: plasma and formed elements.

Step 2: Plasma is the liquid portion of blood and contains water, dissolved proteins (such as albumins, globulins, and fibrinogen), nutrients, hormones, waste products, and electrolytes.

Step 3: Formed elements refer to the cellular components of blood, which include red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes). These elements are suspended in the plasma.

Step 4: Evaluate the incorrect options: Whole blood does not consist only of red blood cells and water, as it contains plasma and other cellular components. It also does not lack dissolved proteins, as plasma is rich in proteins. Additionally, blood is not primarily made up of adipose tissue, which is a type of fat tissue.

Step 5: Conclude that the correct characteristic of whole blood is that it is a connective tissue composed of plasma and formed elements, as this accurately describes its structure and function.
