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 […]

What is Peritectoid?
What is Peritectoid? In binary systems, the peritectoid is the transformation of two solid phases in an alloy system, forming a new phase. These reactions happen in a similar way to peritectic transformations (see Peritectic), however, they only occur in the solid state. Is Cementite FCC or BCC? The alpha phase is called ferrite. Ferrite […]
What are the three main principles of usability testing?
What are the three main principles of usability testing? Main principles of usability testing are: defining the goal, hypothesis, research questions and creating scenarios accordingly. preparing requisites based on scenarios (prototypes – never waste time creating omnicapable prototype, these can be only worth it as design presentations for clients, but not for UTs. How do […]
What are the main sources of error in enthalpy experiments?
What are the main sources of error in enthalpy experiments? Sources of error Likely sources of experimental error in this experiment include improper mixing, the placement of the thermometer bulb onto slowly dissolving solids, incorrect reading of the thermometer, not enough thermometer readings, and spillages. The most probable sources of error are the first two. […]
How do igneous rocks look like?
How do igneous rocks look like? Extrusive, or volcanic, igneous rocks look dull and do not sparkle much because they are fine grained. These crystals make a coarse-grained igneous rock called plutonic, or intrusive, igneous rock because the magma was intruded into cracks deep under the earth’s surface. What type of rock is granite? Granite […]
