How we can say that heat is produced buy electrical appliances |
| Answer» From following examples we can clear:1) When these appliances are in connection with the supply of electricity they become hot but wires remain cold. They consist nichrome which has high resistivity and hence high resistance. Heat produced is directly proportional to the resistance of material through which the current flows.2) The filament of an electric bulb consists of tungsten with a high melting point. A filament is enclosed in a glass envelope which is filled with nitrogen and argon gas. Since the resistance of thin filament is very high, amount of heat production is large same as the electric current that flows through the filament. Due to a large amount of heat production, the filament bulb becomes white hot. Hence filament of bulb emits light and heat. | |

Describe the female reproductive system |
| Answer» The female reproductive system is designed to carry out several functions. It produces the female egg cells necessary for reproduction, called the ova or oocytes. The system is designed to transport the ova to the site of fertilization. Conception, the fertilization of an egg by a sperm, normally occurs in the fallopian tubes. The next step for the fertilized egg is to implant into the walls of the uterus, beginning the initial stages of pregnancy. If fertilization and/or implantation does not take place, the system is designed to menstruate (the monthly shedding of the uterine lining). In addition, the female reproductive system produces female *** hormones that maintain the reproductive cycle | |

What colour of visible spectrum is most effective in the process of photosynthesis ? |
| Answer» Plants use only certain colours from light for the process of photosynthesis. The chlorophyll absorbs blue, red and violet light rays. Photosynthesis occurs more in blue and red light rays and less, or not at all, in green light rays.The light that is absorbed the best is blue, so this shows the highest rate of photosynthesis, after which comes red light. Green light cannot be absorbed by the plant, and thus cannot be used for photosynthesis. Chlorophyll looks green because it absorbs red and blue light, making these colours unavailable to be seen by our eyes. It is the green light which is not absorbed that finally reaches our eyes, making the chlorophyll appear green. | |
