Answer:
Explanation:
since during cellular respiration the carbon dioxide as well as the oxygen is provided through the food as a product of cellular respiration. therefore, energy from the food will be used after it leaves the mitochondrion during cellular respiration, through this the damage cell is repaired through cellular respiration.
Answer: b - Chondroblasts within the cartilage divide and secrete new matrix
Explanation: Chondroblasts are derived from two sources; mesenchymal cells within the center of chondrification and chondrogenic cells of the inner cellular layer of the perichondrium (coverings that lie over most cartilage).
At the chondrification centers, the cartilage forming cells (Chondroblasts) begin to secrete the components of extracellular matrix of cartilage. As the amount of matrix increases, the Chondroblasts become separated from each other and they are located in small cavity within the matrix called lacunae.
Concurrently, the cells differentiate into matured cartilage cells called chondrocytes.
