Two students were testing the amount of fertilizer that would best promote the growth of strawberries in a garden. Which of the
following could be an unavoidable source of experimental error? A.Length of the Study
B.Variation in the Strawberry Plants
C.The cost of Watering the Plants
D.Fertilization during the Study
The correct answer would be option D, that is, fertilization during the study.
The experimental error refers to the dissimilarity between a measurement and the true value or between the two measured values. Experimental error is determined by its accuracy and precision.
A variation in data, or error, basically signifies whatever results in the data to be imperfect, not the human mistakes. In order to correct this, there is a need to get familiar with the unavoidable sources of error and how they take place so that one can reduce their effect and get the best probable data.
Acidic soils mean they have more of Al3+ and H+ ions which are acid forming cations. These cations make alkaline forming ions unavailable to plants as nutrients. When the pH of the soil is raised, the Al3+, Fe3+, and H+ are neutralized. The ions bind with –OH ions hence releasing the ions in the negatively-charged sites on the hummus to play a role in the nutrient exchange.
