Answer:

A scientific experiment refers to a detailed and organized array of steps that are needed to reject or validate the framed hypothesis. The steps, which are incorporated in a scientific experiment are:  

1. Identification of independent variable: The independent variable is the one that can be manipulated or changed in an experiment, that is, the effect of which can be witnessed on a dependent variable.  

2. Address any confounding variable: It is the one that comes from the outside, the changes resulting due to this variable impart an effect over the independent and dependent variables. This variable can bring change in the outcome of the experiment.  

3. Form a non-falsifiable hypothesis: A non-falsifiable hypothesis refers to the one that can be proved true on the basis of the implementation of suitable methodology and research design.

Some people have low levels of calcium circulating in the blood, a condition known as hypocalcemia. while for many this disorder
kap26 [50]

Answer:

low level of calcium would result in fewer signals sent between pre and post synaptic cells.

Explanation:

The calcium has a main role in signal transmission mechanism and here is the mechanism :

1-the impulse reaches the synapse (depolarization which is a voltage change).

2-the voltage gated calcium channels open and let calcium flow into the cell.

3-the calcium causes the synaptic vesicles to rupture and release chemical transmitters which cross the synaptic cleft and finally bind to receptors on the post synaptic cell (transmitting the signal)

so it's obvious that if calcium concentration decreases, the signal transmission also decreases.
