Q: Answer the following question given this paragraph: The winds of a tornado can reach very high speeds. The faster the winds blow, the greater the damage they cause. Wind speed and damage are used to classify tornadoes ( Table below ). Q: How do they classify tornadoes? A:

OPTIONS:
- wind density
- amount of destruction
- wind temperature
- wind speed

A: wind speed

input: OPTIONS:
- maximum energy
- solar energy
- depletion energy
- activation energy Now, answer this question: Answer the following question given this paragraph: Summary A minimum energy (activation energy, Ea) is required for a collision between molecules to result in a chemical reaction. Plots of potential energy for a system versus the reaction coordinate show an energy barrier that must be overcome for the reaction to occur. The arrangement of atoms at the highest point of this barrier is the activated complex, or transition state, of the reaction. At a given temperature, the higher the Ea, the slower the reaction. The fraction of orientations that result in a reaction is the steric factor. The frequency factor, steric factor, and activation energy are related to the rate constant in the Arrhenius equation: k = Ae - Ea / RT. A plot of the natural logarithm of k versus 1/T is a straight line with a slope of Ea/R. Saylor URL: http://www. saylor. org/books.

Answer the following question given this paragraph: Gene cloning is the process of isolating and making copies of a gene. This is useful for many purposes. For example, gene cloning might be used to isolate and make copies of a normal gene for gene therapy. Gene cloning involves four steps: isolation, ligation, transformation, and selection. You can watch an interactive animation about gene cloning at this link: http://www. teachersdomain. org/asset/biot09_int_geneclone/ . Q: What is the process of isolating a specific gene and then making a copy of it for use in gene therapy? A:

OPTIONS:
- attribute cloning
- gene treatment
- gene copying
- gene cloning

Answer: gene cloning
