What would a substance that decreases membrane premeability to sodium increase or decrease the probability of generating a nerve impulse?
Allowing more sodium ions into a nerve generates a nerve impulse. so decreasing membrane permeability of sodium would decrease the probability of generating a nerve impulse.
When a substance changes from a solid to a liquid its density normally decreases. What is happening to the substance's mass and volume to cause this decrease in density?
A decrease in density would indicate a reduction in mass relative to the volume. If the mass decreases but the volume remains the same or increases, then the density would decrease.
What happends to the boiling point of a substance when pressure above it decreases?
The boiling point will also decrease in this case.
What happens to enthalpy when temperature is decreased?
the atoms (or molecules) within the substance move slower, as temperature decreases.
Does epinephrine increase or decrease peristalsis?
decreases it

WOULD A SUBSTANCE THAT DECREASES MEMBRANE PROBABILITY TO SODIUM INCREASE OR DECREASE THE PROBABILITY OF GENERATING A NERVE IMPULSE?
It would decrease the probability of generating a nerve impulse. When a neuron is activiated by a threshold stimulus, the membrane briefly becomes more permeable to sodium. If the permeability is decreased, it will be more difficult for the sodium ions to rush into the cell.

Which is true of drugs that decrease membrane permeability to sodium ions?
It would decrease the probability of generating a nerve impulse. When a neuron is activiated by a threshold stimulus, the membrane briefly becomes more permeable to sodium. If the permeability is decreased, it will be more difficult for the sodium ions to rush into the cell.
Why does the density of liquid increase as it cools?
As something cools down, the kinetic energy of its molecules decrease. This corresponds to a decrease in volume occupied of the substance, so the density decreases.
What happends to the boiling point of a substance when pressure above it decreases?
The boiling point will also decrease in this case.
What decreases an asset and liability?
Decrease in asset means being using of it decreases and liability decrease means payable of debts decreases.
What happens to enthalpy when temperature is decreased?
the atoms (or molecules) within the substance move slower, as temperature decreases.
What happens when the temperature of lava increases?
Its viscosity decreases, which allows it to flow easier.
How do you decrease an asset and decrease owners equity?
Credit Decreases an Asset and Debit decreases Owners Equity.
Why is oedema a symptom of kwashiorkor?
decrease protein intake ------> hypoalbuminemia ------>decreases oncotic pressure ---> increase capillary permeability ----> 1. decrease bl.volume and RBF leads to secretion of renin that stimulate aldosterone secretion and Na and water retention. 2. hemoconcenetration stimulate ADH production results in water retention.
How does sound intensity decrease due to density of a substance it passes through?
The speed of sound and density are related as . So the greater the density the speed of sound decreases.
