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 […]
Why does the solution conduct electricity when the crystals dissolved in water?
Why does the solution conduct electricity when the crystals dissolved in water? When a crystal of an ionic compound dissolves in water, the ions separate. Again, the ions are free to move – so a solution of an ionic compound in water also conducts electricity. Which compound has the most ionic character? The greatest the […]
What is the ideal problem solving method?
What is the ideal problem solving method? IDEAL model consisting of five indictors including (1) Identify the problem: trying to identify problems and make them an opportunity to do something creative, (2) Define goals: set goals in a problem, (3) Explore solution: explore alternative approaches to solving problems, (4) Act on the strategy: anticipate results […]
Does Liquids have a fixed volume?
Does Liquids have a fixed volume? Liquids have a fixed volume but no fixed shape. Gases have no fixed volume and no fixed shape. Gases expand to fill the space available. They can also be compressed into a very small space. Do liquids have no fixed volume? Liquids, because they flow, can occupy whatever shape […]
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 […]
Where is productive efficiency?
Where is productive efficiency? In long-run equilibrium for perfectly competitive markets, productive efficiency occurs at the base of the average total cost curve — i.e. where marginal cost equals average total cost — for each good. What is meant by productive efficiency? Production efficiency is an economic term describing a level in which an economy […]
What are the natural variables of Helmholtz free energy?
What are the natural variables of Helmholtz free energy? The natural variables are temperature, T, and volume, V . If the temperature and volume are held constant, the system will reach the equilibrium state (pressure, P, and entropy, S) with the minimum Helmholtz free energy. What are the four thermodynamic functions? Four important and useful […]
Why does Russia have backwards letters?
Why does Russia have backwards letters? Short answer: Because Russian and Greek sound different. And politics. Longer Answer: Many Slavic languages (Russian included) use what’s called the Cyrillic alphabet. Which language uses a backwards N? Yes, it’s Russian, but Russian isn’t the only language to use this script. This script is called Cyrillic, and is […]
What types of waves do doctors use?
What types of waves do doctors use? Transverse Waves in Medicine Describe three ways that the transverse waves of the electromagnetic spectrum are used in medicine. Explain in your own words how the behaviors and characteristics of each of these waves play a role in the practical application. What type of waves does an MRI […]
What is the highest frequency of sound?
What is the highest frequency of sound? 20 kHz Can high frequency sounds kill you? The general consensus is that a loud enough sound could cause an air embolism in your lungs, which then travels to your heart and kills you. Alternatively, your lungs might simply burst from the increased air pressure. High-intensity ultrasonic sound […]
