What is the purpose of the prototype? A prototype is an early sample, model, or release of a product built to test a concept or process. It is a term used in a variety of contexts, including semantics, design, electronics, and software programming. A prototype is generally used to evaluate a new design to enhance […]

How is glucose prevented from leaving the cell? First Half of Glycolysis (Energy-Requiring Steps) This reaction prevents the phosphorylated glucose molecule from continuing to interact with the GLUT proteins, and it can no longer leave the cell because the negatively charged phosphate will not allow it to cross the hydrophobic interior of the plasma membrane. […]

Can there be 2 experimental groups? The experimental group is the set of subjects exposed to a change in the independent variable. It’s possible for an experiment to contain more than one experimental group. However, in the cleanest experiments, only one variable is changed. What do you need to observe to develop a good experimental […]

How can we overcome modal dispersion? One way to reduce modal dispersion is to use graded-index fiber. Unlike the two distinct materials in a step-index fiber, the graded-index fiber’s cladding is doped so that the refractive index gradually decreases over many layers. Which type of fiber has highest modal dispersion? Multimode fiber What is difference […]

What happens to the pH of a base when water is added? Adding water to an acid or base will change its pH. The acid is becoming less acidic. Similarly, when an alkali is diluted with water the concentration of OH – ions decreases. This causes the pH of the alkali to fall towards 7, […]

What is the Sun an example? The sun is the star that is the central object in the solar system. It is made up of 92% hydrogen, almost 8% helium and the rest is assorted elements. An example of sun is what rises in the east and sets in the west each day. The radiant […]

Why do we save money? The importance of saving money is simple: It allows you to enjoy greater security in your life. If you have cash set aside for emergencies, you have a fallback should something unexpected happen. And, if you have savings set aside for discretionary expenses, you may be able to take risks […]

What are the products in CH4 O2 CH4 CO2 H2O? The reaction is named as combustion reaction. When this reaction takes place, the result is carbon dioxide (CO2), water (H2O), and a great deal of energy. Burning methane releases only carbon dioxide and water. What is the balanced equation for C3H8 O2 CO2 H2O? There […]

How do you use the word use and used? Used to refers to something familiar or routine, as in “I’m used to getting up early for work,” or to say that something repeatedly happened in the past like “we used to go out more.” Use to typically occurs with did; “did you use to work […]

Which of the following capacitor is polarized? Which of the following capacitors is polarized? 1) plastic-film 2) ceramic 3) mica 4) electrolytic 5) NULL What is the difference between polarized and nonpolarized capacitor? The most widely used polarized capacitor is electrolytic type. So basically the difference is change of the manufacturing process for more capacity. […]
