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.
Explanation:
The sugar produced is Glucose. (2)
The cell will commit apoptosis (suicide).
Answer:
Additionally, fish, aquatic plants, and other organisms living in and around the reef would be considered biotic factors. Abiotic factors of a coral reef would include the water surrounding the reef, rocks, pebbles, or sand, and the calcium carbonate "skeleton" of the coral.

Answer:
See the answer below.
Explanation:
The arrival of cacao beans in the factory can be likened to the transcription of mRNA using a DNA template.
Sorting of the best beans at the factory can be likened to splicing process. During splicing, the introns are removed from the newly synthesized mRNA and the exons are joined together. The introns represent the non-coding portion of the mRNA while the exons represent the coding sequence.
The checking of bags by quality control can be likened to the final proofreading of the mRNA after splicing before being transported to the cytoplasm where they are used to synthesize proteins.
The large truck that transports the cacao beans represent the transport proteins that transport the mRNA to the cytoplasm while the chocolate-producing company represents the ribosome which is the site of protein synthesis.
