The graph shows, in a period of time between 1978 and 2010. Therefore, it's related to the last 50 years, not the last 100 years, meaning that alternative D is wrong. The amount of sea ice shown in the graph is shown in the scale of million square miles. So, as the graph shows an initial value around 3.2 (3 millions and 2 hundred miles) and it ends up in a value around 2.2 (2 millions and 2 hundred miles), still the real values are around 2.8 (2 million and 8 hundred thousands initially) and 2.0 (2 millions at the end), having a lower value of 1.8 (1 million and 8 hundred thousand); So, in both scenarios, arctic sea ice has shrunk by 1,000,000 (1.0) square miles, being under 2,000,000, not over. Therefore, the highest number to be inside this amount is 2,000, so the correct answer is A: Arctic sea ice has shrunk by over 2,000 square miles in the last 50 years.
Answer:
Coordinates biofilm formation via chemical signaling among cells. (Ans B)
Explanation:
Quorum sensing in bacteria uses to regulate certain expressions such as phenotype which in turn, coordinate their behavior. Some common phenotype examples are biofilm formation, motility, and virulence factor expression.
Some bacteria have the ability to use quorum sensing to regulate nitrogen fixation, bioluminescence, and sporulation. Quorum sensing regulates genes involved in biofilm development, it helps to promote biofilm dispersion and upregulates the synthesis of surfactant molecules. Quorum sensing and biofilm development are known as social bacterial behaviors.
The correct answer is option A
