Which of the following is a function of bone?
A. Storage of minerals
B. Detoxification of alcohol
C. Secretion of hormones
D. Production of otoliths
The correct answer is a. Storage of minerals. Bones serve as a storage site for minerals such as calcium and phosphorus. These minerals are essential for various bodily functions and can be released from the bones into the bloodstream when needed.
b. Detoxification of alcohol is not a function of bone. This process occurs primarily in the liver.
c. Secretion of hormones is not a function of bone. Hormones are produced and secreted by glands such as the pituitary gland, thyroid gland, and adrenal glands.
d. Production of otoliths is not a function of bone. Otoliths are small calcium carbonate structures found in the inner ear of fish and other vertebrates that help with balance and hearing.
Therefore, the Correct Answer is A.

Q #1: Which of the following is a protein present in blood plasma?
A. Monocytes
B. Platelets
C. Fibrinogen
D. Lymphocytes
Answer Explanation
The correct answer is c. Fibrinogen. Fibrinogen is a protein present in blood plasma that plays a key role in blood clotting. When an injury occurs and bleeding begins, fibrinogen is converted into fibrin, which forms a mesh-like structure that helps to trap blood cells and form a clot.
A. Monocytes are a type of white blood cell, not a protein present in blood plasma.
B. Platelets are cell fragments that play a role in blood clotting, but they are not a protein present in blood plasma.
D. Lymphocytes are a type of white blood cell, not a protein present in blood plasma.

Q #2: Lipids absorbed in the small intestine will first enter which of the following structures?
A. Veins
B. Arteries
C. Lacteal vessels
D. Interstitial spaces
Answer Explanation
The correct answer is c. Lacteal vessels. Lipids absorbed in the small intestine will first enter lacteal vessels, which are small lymphatic vessels located in the villi of the small intestine. These vessels transport the absorbed lipids to the lymphatic system, where they eventually enter the bloodstream.
a. Veins and b. Arteries are blood vessels that transport blood throughout the body. Lipids absorbed in the small intestine do not directly enter these vessels.
d. Interstitial spaces are spaces between cells and tissues that contain interstitial fluid. Lipids absorbed in the small intestine do not directly enter these spaces.

Q #3: A study found two processes, Process A and Process B, to be correlated. Which of the following is true for these processes?
A. The study indicates that Process A causes Process B.
B. The study cannot indicate whether Process A and B have a positive relationship.
C. The study does not indicate a causal relationship between the processes.
D. The study cannot indicate whether Process A and B have a negative relationship.
Answer Explanation
The correct answer is c.
The study does not indicate a causal relationship between the processes. A correlation between two processes means that there is a statistical relationship between them, but it does not necessarily imply causation. In other words, just because two processes are correlated does not mean that one causes the other.
b.The study does not indicate that Process A causes Process B.
b.The study can indicate whether Process A and B have a positive relationship if the correlation is positive.
d. The study can indicate whether Process A and B have a negative relationship if the correlation is negative.
