It is an innate behaviour for reptiles, regardless of the environment. .Select the correct statements: a. 1 Only b. 2 Only c. Both 1 and 2 d. Neither 1 nor 2

  10. Solution (c) Brumation, which is essentially the reptilian equivalent of hibernation, .is a dormant period when cold-blooded reptiles temporarily shut down all activity to conserve energy Brumation is an innate behavior for reptiles, meaning that their bodies tell them to do it naturally, regardless of environment. * Unlike hibernation in mammals, brumation is not a sleeping period for reptiles. Reptiles in brumation still need to drink water and may wake for several days at a time before returning to brumation Different reptiles brumate in different ways. Some tortoises burrow themselves as deep as 6 feet into the ground to wait out seasons Garter snakes huddle into groups to brumate, using their combined body heat to help each other survive.

  11. Q.5) Consider the following statements with respect to 'microbial fuel cell (MFC) 1. It harnesses the power of respiring microbes to convert organic substrates directly into electrical energy 2. It transforms chemical energy into electricity using oxidation reduction reactions . Select the correct statement a. 1Only b. 2 Only c. Both 1 and 2 d. Neither 1 nor 2

  12. Microbial fuel cells work by allowing bacteria to do what they do best, oxidize and reduce organic molecules. 'Bacterial respiration is basically one big redox reaction in which electrons are being moved around. .Whenever you have moving electrons, the potential exists for harnessing an electromotive force to perform useful work. A MFC consists of an anode and a cathode separated by a cation specific membrane. Microbes at the anode oxidize the organic fuel generating protons which pass through the membrane to the cathode, and electrons which pass through the anode to an external circuit to generate a current. . .The trick of course is collecting the electrons released by bacteria as they respire. This leads to two types of MFCs: 1. mediator and 2. mediatorless.
