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.
The substances they need are carbon dioxide, water, and chlorophyll, and the substances produced by photosynthesis is 1 glucose molecule and 6 oxygen molecules
The answer would be A packing becomes less tight. The double bounds create kinks in the chain making it harder for the chains to back tightly
