Hint: Neurons are cells within the nervous system that transmit information to other nerve cells, muscle, or gland cells. Most neurons have a cell body, an axon, and dendrites. The bone matrix is that part of the bone tissue and forms most of the mass of the bone. It is composed of organic and inorganic substances. RBCs are the red blood cells or erythrocytes. It helps to transport oxygen. A lymphocyte is one type of white blood cell in the vertebrate immune system.
Complete answer: A nissl body, also known as nissl substance and nissl material, is a large granular body found in neurons. These granules are of the rough endoplasmic reticulum (RER) with rosettes of free ribosomes. They are the site of protein synthesis.
-Ossein is the organic extracellular matrix of bone, which is made of 95% collagen.
-In mammals, red blood cells are small biconcave cells that at maturity do not contain a nucleus, mitochondria, or any organelles.
-There are two main types of lymphocytes: B cells and T cells. The B cells produce antibodies that are used to attack invading bacteria, viruses, and toxins.
So, the answer is D. 1-b, 2-a, 3-d, and 4-c.
Note: The organic component of the bone matrix includes the collagen and ground substance whereas the inorganic component is the inorganic bone salts, mainly the hydroxyapatite. Lymphocytes include natural killer cells (which function in cell-mediated, cytotoxic innate immunity), T cells (for cell-mediated, cytotoxic adaptive immunity), and B cells (for humoral, antibody-driven adaptive immunity).
