The plasma contains:
A. Sugar
B. Waste
C. Protein
D. Urine

Answer 1

Blood is a body fluid present in humans as well as many other animals that supply the cells with substances such as oxygen and nutrients needed. It is made up of blood cells which in vertebrates are suspended in blood plasma. It contains the building blocks of the body.

Complete answer: Blood has a plasma-called fluid (liquid) where red blood corpuscles (RBCs), white blood corpuscles (WBCs) and platelets are suspended. Proteins, salts and hormones are present in blood plasma. Blood travels to all areas of the body and carries gases, digested food, hormones and waste materials. Sugar, wastes and urine are absent in plasma. Blood comprises two primary protein types: albumin and globulin. These proteins help the body generate substances that it requires for various biological functions. The quantity of total protein in the blood is relatively constant. In human adults, all red blood cells, 60-70 percent of white cells (i.e. granulocytes) and all platelets are formed by the bone marrow. Lymphocytes (20-30 percent of white cells) are generated by the lymphatic tissues, particularly the thymus, spleen, and lymph nodes. Blood has many distinct roles, including transporting the lungs and tissues with oxygen and nutrients. To avoid excess blood loss by creating blood clots has receptors and cells that combat infection.

Note: Ferritin is a globular protein complex which has 24 protein subunits that form a nanocage-like structure with many metal-protein interactions. It is the main intracellular iron-storage protein in both prokaryotes and eukaryotes and retains iron in a soluble and non-toxic form.
