Where is redbone marrow located and what activity occurs in red bone marrow? Give a function of vertebrae Give the name of the vertebrae that have ribs Give the name of the vertebrae in the neck Does compact bone or sponge bone contain red bone marrow? What bones protect the thoracic cavity? Name the type of cell division described by 2n to n If the parent cell has 24 chromosomes, how may does each daughter cell have at the end of meiosis Which blood cells contain respiratory pigment? Which type of blood vessel (artery or vein) has valves? Which type of blood vessel (arteries or veins) has thicker walls? Which chamber of the heart receives venous blood from the systemic circuit?Explanation / Answer
26) Red bone marrow is located in the axial skeleton and hip bones. It is responsible for the formation of blood i.e red blood cells, white blood cells, and platelets.
27) Function of vertebrae are as follows
28) Thoracic vertebrae
29) Cervical vertebrae
30) Spongy bones mostly contain red bone marrow. The trabeculae or spaces in the spongy bones filled with the red bone marrow. For example, they are found at the proximal ends of femur and humerus.
The thoracic vertebrae, the ribs, and the sternum protects the thoracic cavity.
31) Meiosis is the type of cell division described by 2n to n. Therefore, it is also known as reductional division.
32) Each daughter cell has 12 chromosomes at the end of meiosis II. Meiosis is known as reductional division in which one diploid parent cell divides into four genetically identical, haploid daughter cells. In two round of division i.e meiosis I and meiosis II, the chromosome numbers reduced to half.
33) Red blood cells contain a respiratory pigment known as hemoglobin.
34) Veins have valves to prevent the backflow of blood towards the heart.
35) Arteries have thicker walls to withstand the higher pressure of the blood that flows through them.
36) The right atrium receives venous blood (deoxygenated blood) from the systemic circuit via superior and inferior vena cava.
