Answer:

Hypothesis

Explanation:

A hypothesis is a supposition for a phenomenon. It tries to predict the end result of a research, hence it is made based on limited information, but can form the beginning for a study. Although a hypothesis is based on limited information, it is testable and also precise.

A hypothesis helps with making predictions for a scientific study, which can be further tested to ascertain the supposed claim.

For example, although the statement by Ciara was only a prediction with limited evidence, it could be further tested and that makes Ciara's supposition a hypothesis.

<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.
