What else can I help you with?
Would an action potential be possible without the presence of proteins?
No, proteins play a critical role in generating and propagating action potentials in neurons. Channels and pumps made of proteins are responsible for the movement of ions across the cell membrane, which is crucial for the changes in membrane potential that underlie an action potential. Without proteins, the necessary ion movements would not occur, and an action potential would not be possible.
60 percent of volcanoes occur surrounding the Pacific Ocean a location called what?
The "Ring of Fire".
Which term is defined as the sequential pattern of events as they occur in a story?
Plot is the term defined as the sequential pattern of events as they occur in a story. It includes the exposition, rising action, climax, falling action, and resolution.
Does the reactions force occurs before the action force?
The two forces occur at the same time. Sometimes it is a bit arbitrary which force you call "action", and which "reaction". Just remember that forces always occur in pairs.
Does action potentials occur at nodes?
Yes, action potentials occur at the nodes of Ranvier in myelinated neurons. The myelin sheath insulates the axon, forcing the action potential to jump from node to node, a process known as saltatory conduction. This allows for faster conduction of the action potential along the axon.
Corrosion by electrolytic action would be most likely occur where?
Where dissimilar piping joins
Is an action potential necessary for a nerve impulse to occur?
Yes, an action potential is needed for a nerve impulse to occur.
Is a action potential necessary for a nerve impulse to occur?
Yes, an action potential is needed for a nerve impulse to occur.
The combustion reactions that occur in the engines of a rocket lead to pressure gradients that cause the gaseous products to rush out of the rocket into the atmosphere. What is created by this process?
Thrust
How does Newton's Third law apply to bottle rockets?
The rocket's propellant shoots out of one of its ends. Newton said that every action (like rocket propellant shooting out) is accompanied by an equal (same force) but opposite re-action. So, if the propellant shoots out with a force of, say, 1,000 pounds, then the rocket is pushed in the opposite direction (forward, we hope) by 1,000 pounds. It works! Try standing on one tiptoe while holding a weight of 5 or 10 pounds out to your side. Move the weight quickly sideways across your body and you will find your body moving (twisting because of that toe on the floor) in the opposite direction.
A rocket is designed to drop its first stage mid-flight. Due to a malfunction this does not occur. What is a possible result of this malfunction?
The rocket is now too heavy to reach its destination
What is the rising action in the story of shiva's fire?
The rising action in the story of "Shiva's Fire" involves the development of the central conflict surrounding the protagonist's journey towards self-discovery and enlightenment. It includes key events and challenges that propel the story forward, leading towards the climax where significant changes or revelations occur.
When do action- reaction forces occur?
first law
Does the resolution occur before or after the climax and falling action?
The resolution is generally after the falling action and climax.
Does atrial systole occur before or after the firing of the sinoatrial node?
The SA node makes the action potential for the heart. Atrial systole must occur after the action potential.
What action will occur if both the flexors and extensors contracted simultaneously?
If both the flexors and extensors contracted simultaneously there would be no movement in the muscle whatsoever.
