Answer:

In science a hypothesis is useful only if it can be <u><em>tested</em></u>.

Explanation:

In a scientific experiment, a hypothesis can be described as a tentative experiment that can be tested through observations and experimentation. The results inferred from the experiments can prove whether a hypothesis was correct or wrong. Hence, a hypothesis is a very important part for the scientific method of research. The validation of a hypothesis through experimentation brings about theories, facts, laws etc. A hypothesis is made in response to a scientific question.

synapse

neurotransmitter

Explanation:

Neurons are the basic units for the transmission of signals to the central nervous system. The two neurons are connected through the syanpse. Synapse is the space or junction between two nerve cells, or neurons.

The neuron receives signals through dendrites and two neurons  communicate with each other through a chemical called neurotransmitter, which is released at the end of a nerve fibre and carry the signal through the body.

Hence, the correct answers are synapse and neurotransmitter.
