The tube that contains only glass beads is called the control tube. It is used as a control in the germinating seed experiment to provide a baseline comparison for the experimental tube with seeds.
A control in an experiment is a group or sample that is used as a basis of comparison. In this case, the uninoculated broth tube serves as a control to show what the nutrient broth looks like without any microorganisms growing in it. Controls are important in experiments to help researchers determine the effects of the variables being tested.
When Thompson placed the charged metal plates on either side of the glass tube, the beam of electrons was deflected towards the positive side of the tube. This demonstrated that the electrons were negatively charged and attracted towards the positive plate, suggesting the presence of negatively charged particles within the atom.
Well, honey, a control tube is used to provide a baseline for comparison in experiments or tests. It's like having a 'normal' sample to measure against the 'experimental' sample. Without it, you might as well be driving blindfolded on a rollercoaster - dangerous and pointless.
Electrons move from the negative end of the tube to the positive end because they are negatively charged particles that are attracted to the positive charge. This movement creates an electric current in the circuit.

The lavender shield tube collects positive ions, while the light green shield tube collects negative ions. If the lavender shield tube is collected before the light green shield tube, it means that more positive ions were present in the environment than negative ions at that moment.
Electrons have a negative charge and are attracted by the positive end.

To collect a sample gas at the positive electrode during electrolysis for copper, a gas collection tube can be placed directly above the positive electrode. As the electrolysis is carried out, the gas generated at the positive electrode will rise and move into the collection tube, allowing for easy sampling and analysis.
