Answer;
-Neurotransmitters.
One of the first key terms she memorizes is neurotransmitters because these are the chemicals via which neurons communicate with each other.
Explanation;
-Neurons communicate with each other via electrical events called 'action potentials' and chemical neurotransmitters. At the junction between two neurons (synapse), an action potential causes neuron A to release a chemical neurotransmitter.
-Neurons are connected to each other through synapses, sites where signals are transmitted in the form of chemical messengers.

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.
