Solution:

Periosteum, It is dense fibrous membrane covering the surfaces of bones, consisting of an outer fibrous layer and an inner cellular layer. The outer layer is composed mostly of collagen and contains nerve fibres that cause pain when the tissue is damaged. It also contains many blood vessels, branches of which penetrate the bone to supply the osteocytes, or bone cells. These perpendicular branches pass into the bone along channels known as Volkmann canals to the vessels in the haversian canals, which run the length of the bone. Fibres from the inner layer also penetrate the underlying bone, serving with the blood vessels to bind the periosteum to the bone as Sharpey fibres.

The inner layer of the periosteum contains osteoblasts and is most prominent in fetal life and early childhood, when bone formation is at its peak. In adulthood these cells are less evident, but they retain their functional capacities and are vital to the constant remodeling of bone that goes on throughout life. In the event of bone injury, they proliferate greatly to produce new bone in the repair process. Following an injury such as a fracture, the periosteal vessels bleed around the traumatized area, and a clot forms around the fragments of bone. Within two days the osteoblasts multiply, and the cambium expands to become many cell layers thick. The cells then begin to differentiate and lay down new bone between the ends of the fracture.

This is the required solution.

Answer:

The correct answer is - C. Photoautotrophs.

Explanation:

Photoautotrophs are autotrophs or organisms that are able to obtain their food by using photosynthesis. Photosynthesis is the process in which sunlight trapped by the organism and converts to inorganic material such as CO2 and H2O to organic material which is glucose or sugar molecules.

In termite's guts, various types of diverse ways of getting their nutritional needs are found according to the microbes are Chemotrophs, Heterotrophs, parasites, and decomposers.
