Explanation:
The terms C.O.D. (Chemical Oxygen Demand) and B.O.D. (Biochemical Oxygen Demand) are measurements used to determine the amount of organic pollutants present in water.
- C.O.D. (Chemical Oxygen Demand): C.O.D. refers to the amount of oxygen required to chemically oxidize organic compounds in water. It measures both biodegradable and non-biodegradable organic substances.
- B.O.D. (Biochemical Oxygen Demand): B.O.D. refers to the amount of oxygen required by microorganisms to decompose organic matter in water. It measures only biodegradable organic substances.
In the polluted water of industries, the values of C.O.D. and B.O.D. can vary. Based on the given options, the correct answer is option B: C.O.D. much higher than B.O.D. This means that the level of non-biodegradable organic pollutants is significantly higher than the level of biodegradable organic pollutants in the polluted water of industries.
This can be explained as follows:
- Industrial activities often release a wide range of pollutants, including both biodegradable and non-biodegradable substances.
- The presence of non-biodegradable organic compounds such as heavy metals, synthetic chemicals, and toxic substances in industrial wastewater can increase the C.O.D. value.
- These non-biodegradable pollutants are difficult for microorganisms to decompose, resulting in a lower B.O.D. value compared to the C.O.D. value.
- Therefore, in the polluted water of industries, the C.O.D. value is much higher than the B.O.D. value.
Overall, option B: C.O.D. much higher than B.O.D. is the correct answer based on the given information.

Read the following text and answer the following questions on the basis of the same:Light Emitting Diode:It is a heavily doped p-n junction which under forward bias emits spontaneous radiation. The diode is encapsulated with a transparent cover so that emitted light can come out. When the diode is forward biased, electrons are sent from n → p (where they are minority carriers) and holes are sent from p → n (where they are minority carriers). At the junction boundary, the concentration of minority carriers increases as compared to the equilibrium concentration (i.e., when there is no bias).Thus at the junction boundary on either side of the junction, excess minority carriers are there which recombine with majority carriers near the junction. On recombination, the energy is released in the form of photons. Photons with energy equal to or slightly less than the band gap are emitted. When the forward current of the diode is small, the intensity of light emitted is small. As the forward current increases, intensity of light increases and reaches a maximum. Further increase in the forward current results in decrease of light intensity. LED's are biased such that the light emitting efficiency is maximum. The V-I characteristics of a LED is similar to that of a Si junction diode. But, the threshold voltages are much higher and slightly different for each colour. The reverse breakdown voltages of LED's are very low, typically around 5 V. So care should be taken that high reverse voltages do not appear across them. LED's that can emit red, yellow, orange, green and blue light are commercially available.Q. Threshold voltage of LED is

Read the case study given below and answer the questions that follow:Available water resources are degrading rapidly. The major rivers of the country generally retain better water quality in less densely populated upper stretches in hilly areas. In plains, river water is used intensively for irrigation, drinking, domestic and industrial purposes. The drains carrying agricultural (fertilizers and insecticides), domestic (solid and liquid wastes), and industrial effluents join the rivers. The concentration of pollutants in rivers, especially remains very high during the summer season when flow of water is low. The Central Pollution Control Board (CPCB) in collaboration with State Pollution Control Boards has been monitoring water quality of national aquatic resources at 507 stations. The data obtained from these stations show that organic and bacterial contamination continues to be the main source of pollution in rivers. The Yamuna river is the most polluted river in the country between Delhi and Etawah. Other severely polluted rivers are: the Sabarmati at Ahmedabad, the Gomti at Lucknow, the Kali, the Adyar, the Cooum (entire stretches), the Vaigai at Madurai and the Musi of Hyderabad and the Ganga at Kanpur and Varanasi. Ground water pollution has occurred due to high concentrations of heavy/toxic metals, fluoride and nitrates at different parts of the country.Q. When was the CPCB established?
