Final answer:
Red blood cells are primarily formed in the bone marrow, specifically the red bone marrow. The process of producing these cells, known as hematopoiesis, begins at the embryonic stage and continues throughout a person's life, with adult hematopoiesis being largely restricted to certain bones in the body. New red blood cells are continuously produced due to their relatively short lifespan.
Explanation:
Red blood cells are formed in the bone marrow, specifically in the red bone marrow which is a loose collection of cells where hematopoiesis or the production of blood cells occurs. This crucial process of forming blood cells, including red blood cells, is introduced in the embryonic stage in the yolk sac. However, as the embryo develops, this function is taken over by the spleen, liver, and lymph nodes, with the bone marrow eventually assuming most hematopoietic functions. The red blood cells, along with white blood cells and platelets, are all produced in the red bone marrow.
In children, this process can occur in the cavity of long bones, but in adults, it is largely restricted to certain bones such as the cranial and pelvic bones, the vertebrae, the sternum, and parts of the femur and humerus. The lifespan of these cells is relatively brief, so new ones must be continuously produced to maintain healthy bodily functions.

(Initial) (Final)
where, M1 and M2 are initial and final concentration of soution respectively.
V1 and V2 = initial and final volume of solution respectively
Given: M1 = 12 m, V1 = 35 ml and V2 = 1.2 l = 1200 ml
∴ M2 = M1V1/V2 = (12 × 35)/ 1200 = 0.35 m
Final concentration of solution is 0.35 m
Final answer:
The final concentration of the solution prepared by diluting 35.0 ml of 12.0 M HCl to a final volume of 1.20 L is 0.35 M.
Explanation:
The final concentration of a solution prepared by diluting 35.0 ml of 12.0 M HCl to a final volume of 1.20 L can be calculated using the formula for dilution: M1V1 = M2V2. In this formula, M1 is the initial concentration, V1 is the initial volume, M2 is the final concentration, and V2 is the final volume.
Firstly, we convert the initial volume from ml to litres because the final volume is given in litres. So, 35.0 ml = 0.035 L. Therefore, the equation becomes: 12.0 M * 0.035 L = M2 * 1.20 L.
On rearranging the equation to solve for M2, the result is 0.35 M.
