Explanation:
Geologists use the law of superposition to determine the relative ages of sedimentary rock layers.
Conservation biology<span> is the management of nature and of Earth's biodiversity with the aim of protecting species, their habitats, and ecosystems from excessive rates of extinction and the erosion of biotic interactions.</span>
Green plants are autotrophic and synthesize or make their own food by the process of photosynthesis. They do this with the help of carbon dioxide and water in the presence of sunlight. ... Their corresponding modes of nutrition are known as the autotrophic and heterotrophic mode of nutrition.
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.
