What directly causes action potential?
What directly causes action potential? An action potential is caused by either threshold or suprathreshold stimuli upon a neuron. It consists of four phases; hypopolarization, depolarization, overshoot, and repolarization. An action potential propagates along the cell membrane of an axon until it reaches the terminal button. Which part of motor neuron has lowest threshold? axon […]
How do you tell if it is exothermic or endothermic?
How do you tell if it is exothermic or endothermic? An exothermic process releases heat, causing the temperature of the immediate surroundings to rise. An endothermic process absorbs heat and cools the surroundings.” What does it mean when entropy is negative? A negative change in entropy indicates that the disorder of an isolated system has […]
Is n3 Isoelectronic?
Is n3 Isoelectronic? Atoms and ions that have the same electron configuration are said to be isoelectronic. Examples of isoelectronic species are N3–, O2–, F–, Ne, Na+, Mg2+, and Al3+ (1s22s22p6). Is Ca2+ Isoelectronic with AR? For atoms/ions: For example, the K+ ion is isoelectronic with argon. Therefore, K+ and Ar are said to be […]
