d. differentiation
Explanation:
Developmental potential refers to the ability of a cell to form other cell types. A cell may retain the ability to form other cell types or become specialized to perform specific functions. The process of specialization of cells into specific cell types generally limits their ability to form all cell types and is called differentiation.
For example, differentiation of RBCs include loss of organelles and making space for hemoglobin protein. Mature RBCs loose nucleus and can not divide at all.
Answer:
The most important are the lungs, more precisely the alveoli.
Explanation:
Alveoli are structures of the lungs where gas exchange occurs. They allow oxygen from the air to pass into blood. Oxygen diffuses through the walls of alveoli into the capillaries that surround it. Oxygen is then bonded with the iron in red blood cells and travels to the heart. The heart then sends the oxygenated blood out to all the cells in the body.
