The answer is D. all of the above
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.
A chemical equation is said to be balanced when the number of atoms of each element on the reactant side is equal to the number of atoms of those elements on the product side.
The process of photosynthesis involves carbon dioxide and water, which reacted together to form glucose and oxygen. The balanced equation for photosynthesis is given below:
6H2O + 6CO2 = C6H12O6 + 6O2.
Looking at this chemical equation, you will discover that: there are 12 atom of hydrogen, 18 atoms of oxygen and 6 atoms of carbon on both sides of the equation.
