SELECTED QUORA ANSWERS BY EXPERTSONLY ARE INCLUDED .STILL THEY NEED NOT BE 100% CORRECT ANSWERS. Compiled and posted by R. Gopala Krishnan, 80, on 112-12-2023. Q1 Doall mammals feel thirst? How do sea-mammals solve their thirst problem? A1 IraelRamirez, Retired Biopsychologist Updated Jun 10 An interesting question given that ocean-going whales anddolphins can’t drink fresh water. Here’sthe situation. The mOsm numbers describe the amount of dissolved salts;bigger values mean more salt. The body fluids of whales have around300 mOsm but the ocean is around 1,000 mOsm. Marinemammals can get low sodium water from two sources: Burning foods produces some water. Carbohydrates produce slightly morewater than protein or fat. Most marine mammals don’t get a lot of carbohydratein their diet, but metabolic water is a real source of water for marinemammals. In that respect, marine mammals resemble their cousins, camels. Most marine mammals eat fish which happens to have a substantiallylower salt concentration than seawater, in fact close to that ofmammals. That’s a real source of only mildly salty water. Marine mammals generally don’t drink seawater. Marine mammals don’t need to sweat (I don’t know if they can at all?).People can lose a substantial amount of water that way. So their water needs are less than ours. The kidneys of marine mammals have a greater ability to concentratesodium in the urine, so they can retain water better than we can. Q2 Doesfire contain electrons? A2 SilkRoad,8h Yes,but it's not that simple.Fire becomes plasma under ionization. A plasma is a state of matter whereatoms or molecules are so hot that they lose some or all of their electrons,creating a soup of charged particles. You can find plasmas in stars, lightning, neon signs, and yes, fire. But not all the particles in fire are ionized.Some of them are still neutral atoms or molecules thatcan absorb and emit light.Whenthe particles get heated up by the flame, their electrons get excited and jumpto higher energy levels. Whenthey fall back down, they release photons of light with different colors depending on the energydifference. So fire contains both free electronsand bound electrons that can produce light and heat. When we look at fire on an atomiclevel, we can see it's elements. Spectroscopy allows us to analyze thelight emitted by fire and identify the elements and compounds present in it. We can also use thermodynamics tocalculate the temperature and energy of fire based on its chemical reactions. Q3 Whatare some mind-blowing amazing facts about the human body? A3 OmarAl Javed, Amateur Writer Updated 3y Here you go: 1.You'll have a brand-new skeleton in 10 years. 2. You are 1% shorter in the eveningthan in the morning. 3. Kids grow fastest in the summer. 4. Babies don't have kneecaps. You'd think that our kneecaps wouldbe a necessary part of the human body. Not for babies, who aren't born withthem.

You lose almost one-third of your bones as you age. 7. There are no muscles in your fingers. 8. Your tongue is the only musclethat doesn't join two bones. 9.Hair can "taste." Nasal passages and lungs are linedwith fine hairs, or cilia, that detect and sweep out impurities. How do theydetect it? By sensing bitter tastes of the things passing through them (suchas, say, nicotine). When these hairs taste something bitter, they increasetheir rate of movement, attempting to sweep out the bad stuff, according to a 2009 studypublishedby the American Association for the Advancement of Science. 10.Your body position affects your memory. 11.A blink is a micro nap. 12. Your intestine is four times as longas you are. 13. Sneezes can travel up to 20 feet. 14.Your liver can almost completely regrow. 15. Humans are the only animals that weep. While many animals produce tears aslubricants for their eyes, humans are the only ones who cry as an emotionalresponse. Thomas Dixon,PhD, director of the Centre for the History of Emotions at Queen Mary,University of London, suggested that tears serve a social purpose for humansand that, "Even for those who think they really are just weeping fornobody apart from themselves, it's still a sort of performance. You'reshowing yourself things have really got bad, or whatever it might be." My note- Even by thinking oldincidents or things which may happen, many weep either in seclusion or beforeothers. 16. Humans have more than fivesenses. While we have sight, smell, touch,taste, and hearing, humansalso have "proprioception"(sense of space) and"nociception" (sense of pain). There's also"equilibrioception" (sense of balance), "thermoception"(sense of temperature in and around the body), "temporal perception"(sense of time), and more, depending on who you ask. 17. You burn more calories sleepingthan you do watching television. 18. You cannot snore and dream at thesame time. 19. There are more life forms livingon your skin than there are people on the planet. 20. Human thigh bones are strongerthan concrete. 21. You breathe on average about8,409,600 times a year. 22. Our eyes are always the same sizefrom birth, but our nose and ears never stop growing. 23. During your lifetime, you willproduce enough saliva to fill two swimming pools. 24.

This is what makes our hearts beat faster, and causes a loss ofappetite and sleep, and intense feelings of excitement. 34.The human eye technically has the ability to see ultraviolet light. It’s just that our eye lens filters out this naturalability. Some people have undergone surgery to remove this lens so they candetect ultraviolet light. 35. An adult is made up of7,000,000,000,000,000,000,000,000,000 (7 octillion) atoms. To put that intosome kind of perspective, there are only about 300,000,000,000 (300 billion)stars in our galaxy. 36. The amount of heat given off bythe human body in just 30 minutes is enough to bring one gallon of water to aboil. 37.A single human sperm contains the 37.5mb of male DNA required to create a humanchild.

A5 PlasmaTV is a television display technology in which each pixel on the screen is illuminated by a tiny bit ofplasma (charged gas). Theplasma is encased between two thin sheets of glass. Plasma displays aregenerally considered to offer better dark-room viewing and wider viewing anglesthan LCD. Q6 Whydid they stop making plasma TVs? By 2013, they had lost nearly allmarket share due to competition from low-cost LCDs and moreexpensive but high-contrast OLED flat-panel displays. Manufacturing of plasma displays forthe United States retail market ended in 2014, and manufacturing for the Chinese market ended in 2016. Q7 WhyIndia is called motherland and fatherland? A7 Earlier,since individual migration was very less, motherland was used for both the cases. Later came the nationalist concept offatherland to differentiate. Soin short, if anyone is born in India then it is his motherland and if anyoneofficially lives in India then it is his fatherland.10 Apr 2017 -- You received this message because you are subscribed to the Google Groups "Thatha_Patty" group.
