Answer: A). 2.7 million people per year
Explanation:
From 2000 to 2010 is 10 years. Change in population in 10 years = population at the beginning of 2010 minus the population at the beginning of 2000. This is:
309 million -282 million = 27 million.
Therefore average change in population person year = 27 million/10 = 2.7 million per year
The question is incomplete as it does not have the options which are:
A. bioremediation
B. mutualism
C. quorum sensing
D. quorum settling
E. mass-settling
Answer:
C. quorum sensing
Explanation:
Quorum sensing is the gene regulation mechanism used by the bacteria to communicate with the other bacteria. The quorum sensing process depends on the number of bacterial cells or the density of the cells.
When the bacterial number increase in number then the bacterial cells send the signal to the nearby cells and and regulates the expression of the gene. In the given question, the same chemical signal process depends on the density of the cell and thus quorum sensing is correct.
The answer is A, as the protein does not have any affect of the movement of the cologne.
The answer I think is, some diseases the person might have.
