A) Blood = plasma + RBC + WBC + blood platelets
B) Plasma = blood - lymphocytes
C) Neuron = cyton + dendrite + axon + synapse
D) Lymph = plasma + RBC + WBC
Correct Answer: A
Solution :
Blood is a fluid connective tissue. The blood cells are called corpuscles. Plasma represents the matrix of the blood. It is heavier than water. Blood is made up of two components - Plasma and blood cells. Plasma is transparent, slightly alkaline, matrix of blood. It contains 91 - 92% water and 8-9% solid substances. In mammals, blood cells/corpuscles are mainly of three types erythrocytes (RBCs), leucocytes (WBCs) and thrombocytes (platelets). Thus the correct option is- Blood = Plasma + RBC + WBC + Blood platelets.
