Answer:
Eutrophication
Explanation:
Eutrophication is the process where organic matter and nutrients build up in a body of water and increase plant growth.
Synapse that increases in effectiveness because of simultaneous activity in the presynaptic and postsynaptic neurons is called Hebbian Synapse.
<h3>What is Synapse?</h3>
A synapse is a component of the nervous system that enables a neuron (or nerve cell) to transmit an electrical or chemical signal to an additional neuron or to the target effector cell.
The transfer of nerve impulses from one neuron to another requires synapses.
The synapse contributes to the development of memory. Because of the signaling mechanisms of the receptors, which are activated by neurotransmitters across the synaptic cleft, the connection between the two neurons is strengthened when both neurons are engaged at the same time. The capacity of two interconnected brain circuits is thought to influence how well memories are stored. Long-term potentiation is the name for this process of synapse strengthening.

Answer:
The correct answer is option b, that is, enteroendocrine cells.
Explanation:
The specialized cells of the pancreas and the gastrointestinal tract exhibiting endocrine function are termed as enteroendocrine cells. These cells generate gastrointestinal peptides or hormones in response to a distinct kind of stimuli and discharge them into the bloodstream for the systemic effect. These are the most varied endocrine cells found within the body.
The intestinal enteroendocrine cells produce somatostatin, cholecystokinin, motilin, enteroglucagon, and neurotensin hormones. The G cells present within the intestine produce gastrin. In the gastric glands, the gastric enteroendocrine cells are present, which produce histamine, and others like cholecystokinin, alpha and gamma-endorphin, somatostatin, and others.
In the islets of Langerhans, the pancreatic enteroendocrine cells are present, which produce hormones like ghrelin, amylin, somatostatin, and pancreatic polypeptide.
