Pranam Q1 Living organisms consist of millions, billions or trillions of cells. Human bodies have upward of 37 trillion, most of which can only be seen under a microscope. Other organisms, however, have only one cell in their entire body, and humans can see some of these single-cell organisms with the naked eye. Human egg cells, unusually large bacteria, some amoebas and squid nerve cells make up this list. Some people may think the eggs of egg-laying species are single cells, but that is a false classification. In general, the smallest objects the human eye can see without the aid of technology are no smaller than 0.1 millimeters. Q3 I could not understand the question. The gadgets work only on energy. Energy is provided by sources externally and internally. Power failure runs through the inverters and batteries. If you do not have money to store spare batteries (for instance no one will hold a spare battery of the laptop as a spare) then even the battery will fail. When the power system went off for > 3 days when flood hit TN, chargers and battery operated fans and inverters for a day were handy to gain some light and air. One who has enough hair can do a hairdo , others have to break, buy and then use. Q7 In the modern system plugged in does not damage anything. In my home heer as well as in the USA one can see in the dead dark nights red blue yellow dim lights all around. Electronics TVs and simple gadgets may have to be withdrawn when not in use. Are we not keeping the fridge with lowest contents on "ON" even for a year and coming back and using it?; buy a car battery we have to remove. Q8 It is not to be an occurrence every time; potential difference variation or voltage fluctuations might cause the danger when the gadgets are not in right conditions; every gadget is licensed with the safety and security only; in USA all electrical points are at the lower levels only where a child can touch But modern manufacturing guarantees are read over in the 1st 2 pages of the manuals. Q9 Sujatha the writer once wrote whatever you eat upto the tongue is nothing but changed into chemicals and the order of meals is a protocol; you can lie down and use the blanket or blanket yourself and then lie down; so too it is in the brain; so if you take Curd, Rasam and sambar and the payasam and urugai nothing will go wrong. Over-eating might. Q10 Silly question 1 There is no IQ measured nowadays. 2 And as there are super intelligent to stupids, so too among any professions there are variables. Doctors are not exceptionals. Passing the exam whether doctor or any civilservices do not mean any order of intelligence. Exception make the rules too. KR IRS 13822
