Can we create protons? One can obtain a proton by stripping an electron from a hydrogen atom because hydrogen consists of one proton and one electron. This is known as ionization. At Fermilab, we take hydrogen and add an extra electron. This results in negative hydrogen ions. Do protons die? To the best of our […]
How does an inductor discharge?
How does an inductor discharge? When the current through an inductor is increased, it drops a voltage opposing the direction of current flow, acting as a power load. In this condition, the inductor is said to be discharging, because its store of energy is decreasing as it releases energy from its magnetic field to the […]
What organs are affected by multiple sclerosis?
What organs are affected by multiple sclerosis? Summary Multiple sclerosis (MS) is an incurable disease of the central nervous system that can affect the brain, spinal cord and optic nerves. Common symptoms include fatigue, bladder and bowel problems, sexual problems, pain, cognitive and mood changes such as depression, muscular and visual changes. What Neuroglial cell […]
Which is stronger alpha helix or beta-sheet?
Which is stronger alpha helix or beta-sheet? Alpha Helix structure of DNA is more stable than Beta pleated Sheet structure. It is stabilized by the regular formation of hydrogen bonds parallel to the axis of the helix; they are formed between the amino and carbonyl groups of every fourth peptide bond. Which is more stable […]
How do you respond to Do you have any questions for me?
How do you respond to Do you have any questions for me? The best questions will come as a result of listening to the questions the interviewer asks you. A good response to the interviewer asking, “Do you have any questions?” would be: “Yes, I do. From what you’ve been asking during the interview, it […]
What is adaptive radiation explain with an example?
What is adaptive radiation explain with an example? Adaptive radiation is the relatively fast evolution of many species from a single common ancestor. Adaptive radiation generally occurs when an organism enters a new area and different traits affect its survival. An example of adaptive radiation is the development of mammals after the extinction of dinosaurs. […]
How long does it take to recover from low blood sugar?
How long does it take to recover from low blood sugar? It will usually take around 15 minutes to recover from a mild episode of hypoglycaemia. If you have a blood glucose meter, measure your blood sugar again after 15 to 20 minutes. How do you keep your blood sugar from dropping? Eat regular meals […]
What is a double convex lens?
What is a double convex lens? Bi-Convex (Double-Convex) lenses have the same radius of curvature on both sides of the lens and function similarly to plano-convex lenses by focusing parallel rays of light to a single point. Bi-Convex lenses are the best choice when the object and image are at equal or near equal distance […]
What kinds of bonds can happen between the elements of a compound quizlet?
What kinds of bonds can happen between the elements of a compound quizlet? The atoms in a compound are held together by chemical bonds. Either “ionic bonds” (formed when one or more electrons are ‘transferred’ from one atom to another) or “covalent bonds” (formed when atoms ‘share’ electrons instead of transferring them). You just studied […]
