Answer the following question given this paragraph: There are six types of simple machines. Machines that consist of two or more simple machines are called compound machines. Q: How many types of simple machines are there? Choices: - ten types - three types - two types - six types A:
six types
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? Choices: - wind density - amount of destruction - wind temperature - wind speed A:
wind speed
Q: 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. Q: What term means the minimum energy required in order for a collision between molecules to result in a chemical reaction? Choices: - maximum energy - solar energy - depletion energy - activation energy A:
A: activation energy
Question: 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? Choices: - attribute cloning - gene treatment - gene copying - gene cloning A:
Answer: gene cloning

Answer the following question given this paragraph: A wobble base pair is a non-Watson Crick base pairing between two nucleotides in RNA molecules. The four main wobble base pairs are guanine-uracil, inocine-uracil, inosine-adenine, and inosine-cytosine. Wobble base pairs are fundamental in RNA secondary structure and are critical for the proper translation of the genetic code. Inosine is a nucleoside that is formed from the hydrolytic deamination of adenine. Structurally, it resembles guanine, but lacks the 2-amino group. This lack of the 2-amino group allows inosine to form base pairs with uracil, cytosine and adenine, making it a particularly wobbly base. Q: Of the four main wobble base pairs, guanine is paired with what? Choices: - thymine - cytosine - adenine - uracil A:
**Answer**
uracil

Answer the following question given this paragraph: Dura Mater Like a thick cap covering the brain, the dura mater is a tough outer covering. The name comes from the Latin for "tough mother" to represent its physically protective role. It encloses the entire CNS and the major blood vessels that enter the cranium and vertebral cavity. It is directly attached to the inner surface of the bones of the cranium and to the very end of the vertebral cavity. There are infoldings of the dura that fit into large crevasses of the brain. Two infoldings go through the midline separations of the cerebrum and cerebellum; one forms a shelf-like tent between the occipital lobes of the cerebrum and the cerebellum, and the other surrounds the pituitary gland. The dura also surrounds and supports the venous sinuses. Q: Like a thick cap covering the brain, the dura mater is a tough outer covering. the name comes from the latin for? Choices: - back mother - protecting mother - difficult mother - tough mother A:
(Answer)
tough mother
