Why does SO electrical cord have paper inside it?
why is there string or paper in electrical cords
When did you observed that the air inside seemed to become foggy?
When did you observe taht the air inside seemed to become foggy?
What happens when potassium (K ) leaves the neuron?
As potassium leaves the neuron, the inside of the cell will become progressively more negative, which will attract the positive potassium ions, preventing further exodus. If this electrical force is great enough, it will actually draw potassium ions from the outside of the cell back inside.
What is smaller in terms of size than an atom?
Subatomic particles are smaller than atoms. Subatomic particles are found inside the nucleus of an atom and include protons, neutrons, quarks, and gluons. Protons carry a positive electrical charge while neutrons carry a neutral charge. Inside these protons and neutrons are quarks which are held together by gluons. (1 atom = 0.000000001 meters while 1 quark = 0.000000000000000001 meters) The smallest known particle, however, that has mass is the neutrino.
What is inside cells contain DNA and become darkly colored when stained?
chromosomes
When a positive charge is applied to the inside of an axon what is the effect is called?
When a positive charge is applied to the inside of an axon, it creates a depolarization event known as an action potential. This change in electrical charge triggers the propagation of an electrical signal along the axon, allowing for the transmission of information within the nervous system.
How is the electrical charge inside the neuron?
Neurons send messages electrochemically and all chemicals in the body are electrically-charged. When neurons inside the body are electrically-charged, they are called ions. When a neuron is at rest, or not electrically-charged, the inside is negative and the outside is positive.
What does depolarize and repolarize mean?
Depolarization refers to the change in electrical charge across a cell membrane, where the inside becomes less negative. Repolarization is the return to the cell's resting membrane potential after depolarization. These processes are essential for transmitting electrical impulses in nerve and muscle cells.
What is the rapid change in a membreanes potential cause by the depolarization of a neuron?
The rapid change in membrane potential caused by the depolarization of a neuron is known as an action potential. During depolarization, voltage-gated sodium channels open, allowing sodium ions to flow into the cell, causing the inside of the neuron to become more positive. This shift in charge initiates the action potential, which is essential for the transmission of electrical signals along the neuron.
What is depolorization?
Depolarization is a change in a cell's membrane potential, making it more positive, or less negative. In neurons and some other cells, a large enough depolarization may result in an action potential.
What causes the inside of the membrane to reverse charge and begin action potential?
During an action potential, voltage-gated ion channels open in response to depolarization, causing an influx of sodium ions into the cell. This influx of positive ions triggers the reversal of charge inside the membrane, producing an action potential.
When the outside of the neuron cell is more positive than the inside the cell is?
When the outside of the neuron cell is more positive than the inside, the cell is in a state of depolarization. This shift in electrical charge can trigger an action potential, leading to the propagation of nerve impulses along the neuron.
Lacking electrical charge?
The neutron, a subatomic particle inside the nucleus of an atom, does not have a charge.
What is a shift in the electrical potential across a plasma membrane toward 0mv?
A shift in the electrical potential across a plasma membrane toward 0mV is called depolarization. This occurs when the inside of the cell becomes less negative, potentially triggering an action potential in excitable cells like neurons and muscle cells.
How does the substance inside a fluorescent tube change with an electrical charge?
the electrical charge excites the atoms and creates a plasma state that emits light
What lacking electrical charge?
The neutron, a subatomic particle inside the nucleus of an atom, does not have a charge.
What ammo is inside a taser?
The 'ammo' is the electrical charge that zaps your attacker.
