The positive control tube typically contains a known concentration of the target analyte or a reference sample that is expected to yield a positive result in the assay. This ensures that the experimental conditions are suitable for detecting the target and helps validate the results of the test. It serves as a benchmark to confirm that the assay is functioning correctly.
What else can I help you with?
What term is used to describe a test tube with water instead of an enzyme?
A solvent.
In the germinating seed experiment what do you call the tube that contains only glass beads?
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.
When you examined your incubated nutrient broth tube you compared it to an uninoculated broth tube The uninoculated tube was a control What is control?
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.
What happened to the beam when Thompson placed a pair of charged metal plates on either side of the glass tube?
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.
What is the purpose of control tube?
A control tube is used in experiments to provide a baseline for comparisons. It is used to ensure that any changes in the experiment can be attributed to the variables being tested, rather than external factors.
Why do electrons move the negative end of the tube to the positive end?
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.
What is the positive electrode of an electron tube?
anode
Why is you tube called youtube?
You is obvious. YOU control the content. Tube may be in reference to the old monitors, the cathode ray TUBE monitors.
If a lavender Shield tube is collected before a light green shield tube could occur?
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.
What term is used to describe a test tube with water instead of an enzyme?
A solvent.

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.
Why do electrons move from the negatively end of the tube to the positive end?
Electrons have a negative charge and are attracted by the positive end.
Why do electrons move from negative end of the tube to the positive end?
Electrons have a negative charge and are attracted by the positive end.
Why do electron move from the negative end of the tube to the positive end?
Electrons have a negative charge and are attracted by the positive end.
How could a sample gas be collected at the positive electrode when using electrolysis for copper?
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.

How positive rays are produced in a discharge tube?
deflected away from a negative plat
