Why do narcissists avoid answering questions with straight answers? Narcissists don’t answer questions because they like it when you are confused and uncertain. So rather than give you any sort of clarity, they either don’t answer at all, or they only offer very vague answers. Or, in some cases, they’ll say something that is completely […]
How does shape affect diffusion?
How does shape affect diffusion? Diffusion is like going through a net or sieve. Smaller sizes and shapes pass through more easily than large ones. What is the relationship between cell size and diffusion? The surface-to-volume ratio of a sphere is 3/r; as the cell gets bigger, its surface-to-volume ratio decreases, making diffusion less efficient. […]
What is the purpose of thin layer chromatography?
What is the purpose of thin layer chromatography? TLC is a chromatography technique used to separate non-volatile mixtures. Thin-layer chromatography can be used to monitor the progress of a reaction, identify compounds present in a given mixture, and determine the purity of a substance. What are the two major uses of thin layer chromatography? The […]
How do red blood cells and white blood cells work together?
How do red blood cells and white blood cells work together? Red blood cells carry oxygen to all parts of the body. White blood cells help fight infection. Platelets are tiny cells that have a big job in stopping bleeding. Proteins in the blood called clotting factors work to form a clot. What causes white […]
How is density directly proportional to volume?
How is density directly proportional to volume? Density and Volume are inversely proportional to each other. Mass and volume are not the same. When density increases, volume decreases. When volume increases, density decreases. What do density mass and volume have in common? An object’s density is the ratio of mass to volume of an object. […]
What is the order of scientific inquiry?
What is the order of scientific inquiry? It usually consists of six steps: question, observation or investigation, hypothesis, experiment, analysis of data (reviewing what happened during the experiment), and conclusion. Which of the following is the correct order for the steps of scientific inquiry? The correct order of steps of scientific enquiry are observe, question, […]
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 […]
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 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 […]
How do you increase the amplitude of a sound wave?
How do you increase the amplitude of a sound wave? In theory, a sound wave can have any amplitude, and we can boost a wave by multiplying its samples with any arbitrarily large number. What is relation between frequency and voltage? As the voltage increases so does the power out of the area and frequency […]
