What causes sodium voltage-gated channels to open? When a stimulus reaches the threshold at the axon hillock, an action potential is generated. An action potential relies on many protein channels. All the voltage-gated Sodium channels open when the membrane potential reaches around -55 mV and there’s a large influx of Sodium, causing a sharp rise […]
What does the bubbling indicate?
What does the bubbling indicate? When substances are put in the same container like, CaCO3 and HCl . A reaction occurs and bubbles escape the container (effervescence). These bubbles are actually gas fumes, and this shows that a new gaseous product is formed. Here, bubbling indicates our chemical reaction. What are the bubbles that you […]
Can the sign of the acceleration ever be positive for an object that is slowing down?
Can the sign of the acceleration ever be positive for an object that is slowing down? According to our general principle, when an object is slowing down, the acceleration is in the opposite direction as the velocity. Thus, this object also has a positive acceleration. Is it true that acceleration only takes place when speeding […]
Why onion has no chloroplast?
Why onion has no chloroplast? The clear epidermal cells exist in a single layer and do not contain chloroplasts, because the onion fruiting body (bulb) is used for storing energy, not photosynthesis. The vacuole is prominent and present at the center of the cell, surrounded by cytoplasm. Do plant cells have chloroplasts and mitochondria? Plant […]
Why metal is a conductor?
Why metal is a conductor? Metals are an excellent conductor of electricity and heat because the atoms in the metals form a matrix through which outer electrons can move freely. Instead of orbiting their respective atoms, they form a sea of electrons that surround the positive nuclei of the interacting metal ions. Are metals shiny? […]

How do you poop after hip surgery?
How do you poop after hip surgery? After surgery, you should also plan to take a stool softener, such as docusate (Colace). A fiber laxative, such as psyllium (Metamucil), may also be helpful. Purchase a laxative or stool softener before your surgery so that you have it available when you return home. Can you ever […]
What happens when a PWC steering is turned to the right?
Why is it difficult for a high speed car to negotiate an unbanked turn?
Why is it difficult for a high speed car to negotiate an unbanked turn? (a) A huge force is pushing the car outward. (b) The magnitude of the friction force might not be enough to provide the necessary radial acceleration. A car negotiating an unbanked road at high speed is actually accelerating as the direction […]
Why is Con Ed so expensive?
Why is Con Ed so expensive? It’s an increase in the supply charge that’s catching people off-guard. An increase in the “supply charge” has driven up electricity costs for many Con Ed customers. How do I start a Con Ed service? You’ll need to start service. We’ll ask the current account holder or landlord to […]
