What is the relationship between enzymes and activation energy? Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy. What happens when activation energy is lowered? Fortunately, it’s possible to lower the activation […]

Are LED continuous or discrete? LED lights, or “Light Emitting Diodes,” as they are better known, emit a continuous spectrum. The spectrum they cover is not as broad as other colored lights or incandescent lights. How do you know if a variable is discrete? A discrete variable is a variable whose value is obtained by […]

How then does water move up the height of a 40 m tall tree? Water is move up the tree by using cohesion-tension, transpiration pull and the root pressure, technical they all happen at the same time; However, the cohesion-tension get it up to the 10m mark and the transpiration pull and the root pressure […]

Why is sexual […]
