Answer the following question given this paragraph: Birds also have wings that function as an aerofoil . The surface of the aerofoil is curved to help the bird control and use the air currents to fly. Aerofoils are also found on the wings of airplanes. Q: Where are aerofoils found? Choices: - airplanes and plants - birds and busses - birds and cars - birds and airplanes A:
birds and airplanes

Answer the following question given this paragraph: Chromosome, gene, locus and alleles are all related. What is the different between a gene and a locus? Between a gene and an allele? Chromosomes are composed of genes located at specific loci. And genes have different alleles. If genes did not have different alleles, we would genetically be all the same. What does that mean?. Q: We would genetically be all the same if genes did not have different what? Choices: - atoms - antigens - bases - alleles A:
(Answer)
alleles
Ques: Answer the following question given this paragraph: Another kind of respiration takes place within body cells. This kind of respiration is called cellular respiration. It's the process in which cells obtain energy by "burning" glucose. Both types of respiration are connected. Cellular respiration uses oxygen and produces carbon dioxide. Respiration by the respiratory system supplies the oxygen needed for cellular respiration. It also removes the carbon dioxide produced by cellular respiration. Q: Respiration that occurs in the cells is called? Choices: - electromagnetic respiration - plasma respiration - biological respiration - cellular respiration A:
Ans: cellular respiration
(Q).
Answer the following question given this paragraph: Identify evidence for electroweak unification. The quarks in a particle are confined, meaning individual quarks cannot be directly observed. Are gluons confined as well? Explain. Q: The quarks in a particle are confined, meaning individual quarks cannot be what? Choices: - separated - changed - hypothesized - directly observed A:
(A).
directly observed
Ques:Answer the following question given this paragraph: Digestion consists of mechanical and chemical digestion. Q: There are two types of digestion, mechanical and what else? Choices: - radiation - mineral - thermal - chemical A:

Ans:chemical
Ques: Answer the following question given this paragraph: one degree Fahrenheit. Only 100 Celsius degrees span the same range as 180 Fahrenheit degrees, thus one degree on the Celsius scale is 1.8 times larger than one degree on the Fahrenheit scale 180 / 100 = 9 / 5. The Kelvin scale is the temperature scale that is commonly used in science. It is an absolute temperature scale defined to have 0 K at the lowest possible temperature, called absolute zero. The official temperature unit on this scale is the kelvin, which is abbreviated K, and is not accompanied by a degree sign. The freezing and boiling points of water are 273.15 K and 373.15 K, respectively. Thus, the magnitude of temperature differences is the same in units of kelvins and degrees Celsius. Unlike other temperature scales, the Kelvin scale is an absolute scale. It is used extensively in scientific work because a number of physical quantities, such as the volume of an ideal gas, are directly related to absolute temperature. The kelvin is the SI unit used in scientific work. Q: Which temperature scale is commonly used in science? Choices: - ph scale - celsius - centigrade - kelvin scale A:
Ans:
kelvin scale
