Lecithin is (organic chemistry) the principal phospholipid in animals; it is particularly abundant in egg yolks, and is extracted commercially from soy. It is also a major constituent of cell membranes, and is commonly used as a food additive (as an emulsifier). While cephalin is (biochemistry) a phospholipid found particularly in the cells of nervous tissue; it is also the primary phospholipid in bacteria.
Answer: Given your four choices, the best/most correct one would be (c) the sunlight that evaporated water that eventually falls as rain and fills the reservoir. It is the potential energy stored in the reservoir water which is "released" as it is converted to kinetic energy (the movement of water which spins the hydroelectric generator turbine, etc.), but the absolute source of that original potential energy comes from the Sun's action to evaporate lake or ocean water which is returned to Earth as rain ... and it is this rainwater which ultimately fills the reservoir behind the hydroelectric power plant.
Explanation:
C. stratosphere is your answer
Most weather balloons are located in the stratosphere to be able to get extremely accurate and stable results. The ozone layer is also located in this area and helps absorb the sun's harmful UV rays before the light reaches us.

Answer:
Yes. If more scientists complete the same experiment a singular scientist made, and get the same results as the first experiment, the results are strengthened.
