Answer:
Stratum granulosum.
Explanation:
Superficial to the stratum dpinodum is the stratum granulosum (granular layer).
Cell division is the process essential for growth and repair in multi-cellular organisms.
Injury to the tissue can activate surrounding cells to undergo cell division with the help of mitogens. Mitogens are the chemical substances which help in escalating mitotic divisions in the cells.
They act by activating the signal-transduction pathway which involve mitogen-activated protein kinase (MAPK).
Other possible manner could be the loss of density which could lead to the inactivation of contact inhibition. As there is a loss of cells during the injury, it makes an empty space which could also trigger or activate surrounding cell to start cell division.
In addition, at injury site the flow of blood also increases to transport various nutrients, clotting factors, growth factors etc. These increased nutrition and growth factors also speed up the process of mitosis.
If oxygen is allowed to be present only glycolysis will happen.
Answer:
social facilitation
Explanation:
This ability or improvement in teh performance of a person when they work in the presence of others is called social facilitation.
The definition was first put forward in 1898 by Norman Triplett; in 1920 psychologist Floyd Allport classified it as social facilitation.
For example, assume your employer has asked you to perform a fairly simple job, such as cleaning up a specific area of work. Social facilitation theory suggests that if there were people watching you when you were working, you'd probably go the extra measures to put it in its place and make the area very clean.
Hence, the correct answer is social facilitation.
