How do you interpret electrophoresis?
In electrophoresis, DNA is subjected to an electric field which causes the genetic material to migrate in a direction from a cathode to an anode. The DNA that is closest to the anode is determined to be shorter in length compared to the DNA that is closer to the anode. This is explained by fact that the smaller fragments of DNA are better able to travel through the porous gel.
What happen to the speimen if you move the slide to the left using a microscope?
If you move the slide to the left using a microscope, the specimen will appear to move to the right in the field of view. This is because the movement of the slide in one direction causes the specimen to move in the opposite direction within the field of view of the microscope.
Why do a series of bands appear on the gel during gel electrophoresis?
During gel electrophoresis, a series of bands appear on the gel because the DNA molecules are separated based on their size and charge as they move through the gel in response to an electric field. The smaller DNA molecules move faster and travel further through the gel, resulting in distinct bands that represent different sizes of DNA fragments.
How do electrons move in an atom?
Electons make part of molecules. Air molecules are constituted mainly of hydrogen and oxygen atoms, (and other elements like nitrogen) Such molecules move freely in space, but it can't move alone, protons and neutrons are part of air molecules, except in electric circuit where electrons move alone inside of conductors.
Is it true that once equilibrium is reached roughly equal numbers of molecules move in either direction across a semipermeable membrane?
Yes, once equilibrium is reached, the number of molecules moving in either direction across a semipermeable membrane will be roughly equal. This is because at equilibrium, the concentration of molecules is the same on both sides of the membrane, resulting in an equal likelihood of molecules moving in either direction to maintain balance.
A what will move in the direction of the arrows on the electric field lines?
A positive charge will move in the direction of the arrows on the electric field lines. Electric field lines show the direction a positive test charge would move if placed in the field.
What is the relationship between the direction of the e0 electric field and the movement of charged particles in a given system?
The direction of the electric field (E) determines the direction in which charged particles will move in a given system. Charged particles will move in the direction of the electric field if they are positive, and opposite to the direction of the electric field if they are negative.
How can one determine the direction of the electric field?
To determine the direction of the electric field, you can use a positive test charge. The direction of the electric field is the direction in which a positive test charge would move if placed in that field.
If you place a charge into an electric field it will move in the direction indicated by the electric field lines?
Yes, a charge placed in an electric field will experience a force and move in the direction of the electric field lines if it is positive, or opposite to the direction if the charge is negative. The force on the charge is proportional to the charge itself and the strength of the electric field at that location.
Does an electric field have strength but no direction?
It has plenty of direction. The direction of the electric field at any point in it is the direction of the force that would be felt by an infinitesimally small positive charge placed at that point.
What is the trajectory of a charge in an electric field?
The trajectory of a charge in an electric field is determined by the direction and strength of the electric field. The charge will experience a force in the direction of the electric field, causing it to move along a path determined by the field's characteristics.
If you place a charge into an electric fieldit will move in the direction indicated by the electric field lines?
Yes, a charge placed in an electric field will experience a force in the direction of the field lines due to the interaction between the charge and the field. The charge will move along the field lines if it is free to do so.
What determines the direction of the electric field in a given region?
The direction of the electric field in a given region is determined by the direction in which a positive test charge would move if placed in that region.
In a electric field and stream of electrons will behave in what way?
In an electric field, electrons will experience a force and move in the direction opposite to the field (from negative to positive). The electrons will accelerate in this direction.
When Electric field lines point in the opposite direction changes would move if they were in the field?
If electric field lines point in opposite directions, charges placed in the field would experience a force in the direction of the stronger field. Charges will move in response to this net force, accelerating in the direction of the stronger field lines.
Electric field lines point in the opposite direction charges would move if they were in the field?
positive
Why are electric field drawn with arrows?
Electric field lines are drawn with arrows to show the direction of the force that a positive test charge would experience if placed in the field. The direction of the electric field at any point is the direction that a positive test charge would move when placed in the field at that point.
