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.
Griffith's experiment worked with two types of pneumococcal bacteria (a rough type and a smooth type) and identified that a "transforming principle" could transform them from one type to another.
At first, bacteriologists suspected the transforming factor was a protein. The "transforming principle" could be precipitated with alcohol, which showed that it was not a carbohydrate. But Avery and McCarty observed that proteases (enzymes that degrade proteins) did not destroy the transforming principle. Neither did lipases (enzymes that digest lipids). Later they found that the transforming substance was made of nucleic acids but ribonuclease (which digests RNA) did not inactivate the substance. By this method, they were able to obtain small amounts of highly purified transforming principle, which they could then analyze through other tests to determine its identity, which corresponded to DNA.
The right answer is D. renal regulation.
Among the many factors that modulate tension (vessels, heart strength, blood volume ...), the kidney plays a vital role because it makes an enzyme called renin that helps increase blood pressure and it regulates the outflow of sodium and water, which contribute to the elevation or diminution of blood pressure in the arteries.
In active transport carrier proteins are used.
