When Loewi triggered a nerve that affected a frog's heart rate, he was able to remove fluid from the region surrounding the heart, transfer it to another frog's heart, and subsequently affect that frog's heart rate as well.
<h3>What are Neurotransmitters?
</h3>
Neurotransmitters, which are organic compounds, play a major role in the language that neurons use to communicate with one another and with their final targets. Following electrical stimulation, these substances are produced and act on their particular receptors to start a response that can be as simple as a muscle contraction or as extremely complex as starting a chain reaction that eventually changes how the organism behaves. Neurotransmitters can have multiple functions; depending on where they act, they can be neuromodulators or, in some cases, neurohormones.

Copying my answer from this question from another student who asked the same one:
Social Darwinism is the belief that people and business are subject to the same laws of nature and natural selection. This has been used by business leaders, both in the Gilded Age and today, to create a belief that the strongest businesses are the ones that survive because they survive the competitive process of natural selection.
So, massive oil companies and railroad companies (and tech companies and banks today) used social darwinism to explain their rise to almost monopoly status as a "natural" thing that was accomplished merely using the laws of nature.

- Treat the <u>sewage</u> before it is released into the water body.
Explanation:

Thus, the correct form is 'sewage.'
