If you multiply a negative by a negative is it a positive?
Yes, any time you multiply a negative by a negative, it automatically becomes a positive.
What will happen to the slope of a line if the line is shifted so that the y intercept increases and the x intercept remains the same?
The answer depends on the signs of the original intercepts.x negative, y negative: negative slope becomes less negative and could go positive.x negative, y positive: positive slope becomes greater.x positive, y negative: positive slope becomes less positive and could go negative.x positive, y positive: negative slope becomes more negative.For 1 and 3, the slope changes sign when the y intercept crosses the origin.
When you add a negative number by a negative number do you get a negative or positive number?
You get a positive number because a negative number reverses the other negative so it becomes a positive number.
What does it mean for a negative to be decreased by a negative?
It becomes less negative To explain. Lets take a negative, eg -5. If we decrease it by 1, it becomes -6 (where 1 is positive) Thus if we decrease it by -1, it becomes -4 (as the -1 is negative) Note that the final number could be positive, For example, if you decrease -5 by -6, you get +1
Are all whole numbers positive or negative?
All integers can be positive or negative, including zero. But zero on its own is neither positive nor negative. It is directly inbetween where one becomes the other.
If a resting potential becomes more negative what happens to the cell?
If the resting potential becomes more negative, the cell becomes hyperpolarized. This means that the inside of the cell is more negative compared to the outside, making it less likely for the cell to depolarize and generate an action potential. Hyperpolarization can prevent the cell from firing action potentials.
During depolarization does the neurons membrane become negative?
During depolarization, the neuron's membrane potential becomes less negative as positive ions enter the cell. This is due to the opening of voltage-gated sodium channels, allowing sodium ions to flow into the cell.
If a resting neuron is stimulated and there is an inward flow of positive charges into the cell the membrane potential will?
If a resting neuron is stimulated and there is an inward flow of positive charges into the cell, the membrane potential will depolarize, meaning the inside of the cell becomes less negative. This can trigger an action potential if the depolarization reaches the threshold level.
How is the resting potential different from repolarization?
The resting potential is the stable membrane potential of a cell at rest, typically around -70mV. Repolarization refers to the return of the membrane potential to its resting value after depolarization, where the cell becomes more negative again due to potassium channels opening.
What is a reduction in membrane potential called?
A reduction in membrane potential is called hyperpolarization. This occurs when the inside of the cell becomes more negative than the outside, making it less likely for the cell to generate an action potential.
The process of depolarization and repolarization is called?
The process of depolarization and repolarization is called an action potential. During depolarization, the cell's membrane potential becomes more positive, while during repolarization, the membrane potential returns to its resting state.
When three negative are multiplied is the product positive or negative?
It is a positive. When you multiply a negative and a negative, it becomes a positive, then you multipy the positive with the other positive
Influx of Na plus till 70mV?
When the membrane potential reaches around +70mV, the voltage-gated sodium channels start to inactivate, reducing the influx of sodium ions. This occurs during the repolarization phase of the action potential, where potassium channels open and potassium efflux causes the membrane potential to return to its resting value.
How do you add a negative by a negative?
you make it a positive because negative add negative becomes a positive
Describe the action of depolarization and repolarization?
Depolarization is the process where the membrane potential becomes less negative, moving towards zero or even becoming positive. This occurs when sodium ions rush into the cell. Repolarization is the return of the membrane potential back to its resting state, following depolarization, usually through the efflux of potassium ions from the cell.
What happens when its a negative times positive?
Becomes a negative.
If your positive and negative number are the same does it become a negative number or positive number?
It depends on what you are doing to the two identical numbers. If you are multiplying them, it becomes a negative. If you are dividing them, it becomes a negative. If you are adding them, it will always be zero (e.g., 2+ -2 = 0, etc.). There are two ways to subtract. If you are subtracting a positive from a negative, the number remains negative. If you are subtracting a negative from a positive, or a negative from a negative, the negative becomes a positive and you just add from there.
