Yes, any time you multiply a negative by a negative, it automatically becomes a positive.
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.
You get a positive number because a negative number reverses the other negative so it becomes a positive number.
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
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.
When the membrane potential becomes more negative it is being hyperpolarized. Remember the resting membrane potential is already at a negative state (~70mV). So if you are making a comparison of a membrane potential that is hyperpolarized in comparison to a resting membrane potential, the resting membrane potential is said to be more depolarized.When the membrane potential becomes more positive it is called depolarization.
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 depolarize, meaning the inside of the cell becomes less negative. This can trigger an action potential if the depolarization reaches the threshold level.
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.
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.
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
you make it a positive because negative add negative becomes a positive
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.
The electrical potential difference across a cell membrane (the resting potential) is around -65 mV, inside negative. In nerve cells (neurones) or muscle cells this potential difference is reversed during an action potential. Sodium (Na+) channels open and Na+ ions enter the cell down their concentration gradient. This entry of positive charge depolarises the membrane ie it cancels out the resting pootential and then reverses it, so the potential becomes positive inside and negative outside, giving a potential of about +50mV.
Becomes a negative.
Voltage-gated sodium channels open during the depolarization phase of an action potential, when the membrane potential becomes more positive.
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.
