Some long-exploited biofuels, such as wood, can be used directly as a raw material that is burned to produce heat. The heat, in turn, can be used to run generators in a power plant to produce electricity. A number of existing power facilities burn grass, wood, or other kinds of biomass. Liquid biofuels are of … Read more DMPQ: What are the different types of Biofuels?
Reflex action is an immediate involuntary response to a stimulus. In an involuntary response, a sensory impulse on reaching central nervous system is itself returned to a specific effector as a motor impulse without neuronal analysis and integration. Reflex responses occur below the level of consciousness. Reflex actions are sudden and autonomic. For instance, if … Read more DMPQ- Explain Reflex action with examples.
