Answer:
Osteochondral Progenitor cells
Explanation:
Osteochondral Progenitor cells are cells that can form a specific type of tissue. These cells form cells that can give rise to the bone and its components, especially fibers. These Progenitor cells originate from the mesenchymal stem cells.
The cells which form the bone are known as the osteoblasts and the cell which forms the fiber is known as the chondroblasts.
Thus, Osteochondral Progenitor cells is correct.
B)weathering is the main way phosphorous is recycled
The answer is A: least explosive
Answer:
Option C, shared DNA sequences
Explanation:
Complete question -
What evidence suggests that vertebrates are more closely related to echinoderms than are any other invertebrate phyla?
- shared patterns of development
- shared morphology
- shared DNA sequences
Solution
Vertebrates have true backbone while invertebrates lack true backbone. Among the invertebrates, the echinoderm phylum is closely related to vertebrates as the echinoderm possesses notochord (similar to backbone) during their early stage development which disappears later.
Through the genomic sequence studies it has been found that echinoderms are similar to vertebrates in many ways. Echinoderms have diverged from deuterostomes along with human and hence pose some genetic similarity which can be devised through study of common DNA sequences
Hence, option C is correct
