Answer the following question given this paragraph: Figure 10.18 The first image shows how helicopters store large amounts of rotational kinetic energy in their blades. This energy must be put into the blades before takeoff and maintained until the end of the flight. The engines do not have enough power to simultaneously provide lift and put significant rotational energy into the blades. The second image shows a helicopter from the Auckland Westpac Rescue Helicopter Service. Over 50,000 lives have been saved since its operations beginning in 1973. Here, a water rescue operation is shown. (credit: 111 Emergency, Flickr). Q: Helicopters store large amounts of rotational energy of what type in their blades? Choices: - magnetic - seismic - thermal - kinetic A:
kinetic

Answer the following question given this paragraph: A polypeptide is a sequence of amino acids between ten and one hundred in length. A protein is a peptide that is greater than one hundred amino acids in length. Proteins are very prevalent in living organisms. Hair, skin, nails, muscles, and the hemoglobin in red blood cells are some of the important parts of your body that are made of different proteins. The wide array of chemical and physiological properties of proteins is a function of their amino acid sequences. Since proteins generally consist of one hundred or more amino acids, the number of amino acid sequences that are possible is virtually limitless. Q: How many amino acids generally consist in protien? Choices: - 13 or more - 7 or more - 67 or more - 100 or more A:
(Answer)
100 or more

Ques:Answer the following question given this paragraph: Minerals are chemical elements that are essential for body processes. They include calcium, which helps form strong bones and teeth, and potassium, which is needed for normal nerve and muscle function. Good sources of minerals include leafy, green vegetables, whole grains, milk, and meats. Q: What chemical element helps forms strong bones and teeth in humans? Choices: - iron - potassium - magnesium - calcium A:

Ans:calcium
Question: Answer the following question given this paragraph: Giant elliptical galaxies contain over a trillion stars. Elliptical galaxies are red to yellow in color because they contain mostly old stars. Most contain very little gas and dust because the material has already formed into stars. Q: Which type of galaxies contain very little gas and dust, are red to yellow in color, contain over a trillion stars and have mostly old stars? Choices: - blue elliptical galaxies - giant orbital galaxies - giant gaseous galaxies - giant elliptical galaxies A:
Answer:
giant elliptical galaxies
