A well written multiple-choice question avoids obviously wrong or implausible distractors (such as the non-Indian city of Detroit being included in the third example), so that the question makes sense when read with each of the distractors as well as with the correct answer. A more difficult and well-written multiple choice question is as follows:
The examination consisted of one paper containing 180 objective type questions from Physics, Chemistry and Biology (Botany & Zoology), having 45 questions from each subject. The exam duration was 3 hours. Each question carried 4 marks. For each incorrect response, one mark used to be deducted from the total score.
Continuous and Comprehensive Evaluation (CCE) was a process of assessment, mandated by the Right to Education Act, of India in 2009.This approach to assessment was introduced by state governments in India, as well as by the Central Board of Secondary Education in India, for students of sixth to tenth grades and twelfth in some schools.
An aqueous solution is a solution in which the solvent is water. It is mostly shown in chemical equations by appending (aq) to the relevant chemical formula . For example, a solution of table salt , also known as sodium chloride (NaCl), in water would be represented as Na + (aq) + Cl − (aq) .
In continuous-flow solution culture, the nutrient solution constantly flows past the roots. It is much easier to automate than the static solution culture because sampling and adjustments to the temperature, pH, and nutrient concentrations can be made in a large storage tank that has potential to serve thousands of plants.
The poem Sabse Khatarnak by the Hindi poet Pash was included in the NCERT textbook for 11th standard Hindi students in 2006. In 2017, the BJP government affiliated RSS tried to remove it but failed. [25] [26] The NCERT made two controversial changes to the class XII political science textbook ‘Politics in India Since Independence’ in 2017.
The Debye–Hückel theory was proposed by Peter Debye and Erich Hückel as a theoretical explanation for departures from ideality in solutions of electrolytes and plasmas. [1] It is a linearized Poisson–Boltzmann model , which assumes an extremely simplified model of electrolyte solution but nevertheless gave accurate predictions of mean ...
The reduced osmolarity oral rehydration solution has lower concentrations of glucose and sodium chloride than the original solution, but the concentrations of potassium and citrate are unchanged. [28] [13] [29] [30] The reduced osmolarity solution has been criticized by some for not providing enough sodium for adults with cholera. [31]
