The sudden drop in blood pressure after a motor bike accident is due to the intensive loss of blood that reduces the blood volume of the body.
Blood is the red-colored fluid present inside the body and pumped by the heart. It consists of RBCs, WBCs and platelets. Its function is to transport oxygen carbon dioxide food, hormones from one part of the body to another through the RBCs. The red color of the blood is due to the pigment hemoglobin. 
Blood pressure is the pressure with which the blood flows into the arteries of the body. It is of two types: systolic pressure and diastolic pressure. The ideal blood pressure must be approximately 120/80 mmHg.

Answer:
B. They determine the structural and functional characteristics of each individual
Explanation:
Genes are present in all plants and in all prokaryotes, so answer choices A and E are incorrect. Genes are present in all living things.
Genes do determine the structural characteristics of each individual, but they also determine the functional characteristics. 
Structure, which is controlled by genes, directly affects function. For example, a gene could code for a specific protein's structure, which will in turn give it a specific function.
So, the correct answer is B.
