Would a substance that decreases membrane permeability to sodium increase or decrease the generating of a nerve impulse?
A substance that decreases membrane permeability to sodium would decrease the generation of a nerve impulse. This is because sodium ions play a crucial role in depolarizing the membrane and initiating nerve impulses. By reducing sodium influx into the cell, the ability of the neuron to generate an action potential would be diminished.
When one drug potentates or diminished the action of another drug?
When one drug potentiates the action of another drug, it enhances or magnifies its effects, either by increasing its efficacy or prolonging its duration. Conversely, when one drug diminishes the action of another drug, it decreases its effectiveness or weakens its impact, potentially leading to reduced therapeutic benefits.
What are the benefits of using Teflon stir bars in laboratory experiments?
Teflon stir bars are beneficial in laboratory experiments because they are chemically inert, resistant to corrosion, and can withstand high temperatures. They also provide smooth stirring action and are easy to clean, making them ideal for a wide range of experiments.
Why is decisiveness important?
We have an obligation to use American taxpayer dollars as if they were our own
What messages provide chemical information that prevents or decreases the likelihood that the receiving neuron will fire?
Inhibitory messages provide chemical information that prevents or decreases the likelihood that the receiving neuron will fire. These messages typically involve neurotransmitters such as GABA or glycine, which hyperpolarize the neuron's membrane potential, making it less likely to reach the threshold for firing an action potential.
How At high temperatures the rate of enzyme action decreases because the increased heat?
alters the active site of the enzyme
How heart rate decreases in obstructive jaundice?
Because bile salts have a depressant action on SA node..
When the parachute deploys and opens does this action increases or decreases drag?
it decreases!
The tension decreases in anticipation of the end of the story?
Falling action. Apex.
What happens to capillary action as soil particle size decreases?
Capillary action increases as soil particle size decreases because smaller particles have higher surface area that enhances water retention and movement between them. Smaller particles create a tighter network of capillaries, allowing water to move more readily through the soil.
How do plants and trees use capillary action?
The water pressure decreases as it rises up the tree. This is because the capillary action is fighting the weight of the water. Although the xylem tube is very thin, and therefore the weight of the water is very low, it is not zero. Eventually, the effects of gravity on the water starts to equal the effects of capillary action. Scientists have found that the pressure inside the xylem decreases with the height of the tree, and similarly, the size of the redwood leaves decreases with the decrease in pressure
Why does conduction velocity decrease when temperature is lowered?
Conduction velocity decreases when temperature is lowered because lower temperatures reduce the kinetic energy of molecules, leading to slower movement of ions across cell membranes. This results in decreased rates of depolarization and repolarization during action potentials. Additionally, the viscosity of the surrounding extracellular fluid can increase at lower temperatures, further impeding the movement of ions. Overall, these factors contribute to a slower conduction velocity in neural and muscular tissues.
How can the rate of microbe action be increased?
Increase the media
The potential of electrons in a circuit can be increased by?
The action of a battery
What is the effect of increasing the foltage and how does this change correlate to changes in the nerve?
Increasing the voltage in a nerve can lead to an increased rate of nerve firing, resulting in more frequent action potentials. This can affect the overall excitability and sensitivity of the nerve. As voltage increases, the threshold for eliciting an action potential decreases, making the nerve more likely to fire in response to stimuli.
What are the release dates for Temperatures Rising - 1972 Lights Camera Action 1-10?
Temperatures Rising - 1972 Lights Camera Action 1-10 was released on: USA: 21 November 1972
Is it true that when the board of directors declares a cash or stock dividend this action decreases retained earnings?
yes it is..
