Q1 Neanderthalsand other early human species are always depicted as living in caves, but werethere actually enough caves around for all of them? What kind of shelter wouldthey use otherwise? A1 MattRiggsby BA Anthropoogy, U.C. Berkeley Fri No, there wouldn’thave been enough caves. Many regions have few caves or no caves at all. But it’s kind ofmoot because even where they were available people didn’t live in caves. Cavesare terrible places to live. They’re dark, they’re often cold anduncomfortable, air circulation is poor, and bringing in fire to fix the firsttwo problems makes the third one worse. Besides, our distant ancestors werenomadic hunter-gatherers, moving across the landscape with the seasons. Theydid sometimes shelter in cave mouths, if they were available, though not deeperinside [1]. They might also take shelter beneath underhanging cliffs, thickforest canopies, improvised shelters like lean-tos, in temporary huts, or undernothing at all, depending on the weather. People did sometimes go deeper into caves,but not to live there. We know they went there from the existence of cavepaintings. However, because caves don’t contain the kinds of material remains we’dexpect from sites were people lived (hearths, food remains, debitage frommaking stone tools, etc.), it’s pretty clear that they were going there just tomake those paintings. Q2 Whydoes chalk stay on the blackboard? A2 MuneerAhamad Shaik , MSc Science & Invention andInventions, National Institute of Technology, Rourkela (2018)Answered August24, 2019 There are twophenomena in action here. First would be an adhesive force. Different types ofmolecules usually have certain attractive forces between them due to variousother causes, which appear as adhesive forces. Such attractive forces betweensimilar molecules are called cohesive forces. These forces keep a chunk ofchalk together as a lump. Anyway, had the chalkboard been perfectly smooth, thechalk would have to depend on the adhesive forces between the board and thechalk. This wouldn’t be that successful in keeping a significant amount ofchalk to the board. Here, the second reason comes to play. If we look at thesurface of the chalkboard, we would notice that its surface isn’t a smoothsurface. It has microscopic ridges and grooves randomly distributed in size. When both thesurfaces are rubbed, the chalk powder deposits in the grooves of the board andstays in them with the help of adhesive and cohesive forces playing to keep itin contact with the surface. Chalk and boardsurfaces before scraping Calk powderdeposited after scraping In terms of energy,the energy you exert on the chalk while writing, is used to powder the solidchalk and push it in the grooves. Q3 Whicheating habit is ordinary in your country but strange in the rest of the world? A3 RekhaDasnurkarFormer Marketing and Sales ProfessionalJuly 26 Traditionally inmost Indian families, wasting food is considered a sin. In my family, whateverthat is cooked, is to be served to everyone. We take repeat helpings if welike, but whatever that is first served, every grain of it, has to be eaten.For those who waste food, we remind them that thousands of people and childrenin India and some poor countries starve to death. Our first course inlunch is roti or chapati or bhakri which is eaten with cooked vegetables anddaal. We eat in stainless steel plates and use steel bowls. 2. Look below.After eating rotis, the left-over items in the plate are deftly mixed togetherwith rice- using the right hand. 3. Look below. Thismixture is eaten, gathered together with our fingers and slurped. Palm has tostay clean. 4. Look below. Theentire plate is swept clean and the fingers licked……….. 5. ………..till onewonders if anyone has eaten in that plate or is it a fresh clean plate. 🤔🤔?(Look below) P.S : Not everyonecleans their plate like this. I simply love the perfect balance of the slightlytangy, slightly sweetish, slightly spicy, slightly salty thick flowing daal inmy plate. I don't waste a single drop of it. The beauty is, no-one calls me badmannered or greedy when I do that at home or in a regular Indian eatery. In ourcountry, its ‘Chalta hain’ (acceptable)! Q4 Whydidn't dinosaur bones decompose? A4 MattRiggsby MA Archaeology, Boston University Sat They did. All thosefossils we find? They’re not bone. They’re fossils. A fossil used to bea bone. However, through certain chemical processes slowly taking place in thesoil, all the organic components are replaced by minerals. Eventually, you geta mineral deposit which is shaped like the bone it replaced but contains noactual bone. Most fossils are made of calcite, though depending on geologicalconditions, there may be different minerals involved.

Q7 Whatare some real life examples of the placebo effect? A7 SrinathNalluri Most Viewed Writer in Behavioral, Social & Human PsychologyJuly 20 In a school, ifteacher tells Ice floats on water Prism separates white light into sevencolours Never add water to acid. The student willask ‘How?’ and ‘Why? ’. The teacher has toexplain logically to make them understand. Otherwise they may not accept whatshe says. Whereas When someone tells This religion says Don’t eat non-vegetarian on Saturday. Homosexuality is a sin. Abortion is prohibited. No drinking or sex work. Girls should wear a burqa. Don’t eat beef or pork. Don’t let women inside temples duringperiods. People follow it.They believe since everyone are doing it, it should be right. They don’t questionor think about the context it was said or whether it is valid today. They think thattheir life is good because they follow everything in a 1500–2000+ years oldmanual, and please good. Any one who does the opposite is considered a sin. Organised religionis one of the biggest ever placebos on this earth. They teach byauthority. They list down do’s and dont’s, what-to and what-not-to, that givelittle room for thinking and cross-questioning. It is a soft-militaristiclifestyle popularly followed by billions of people. Overtime, they getaddicted to these teachings so much that they refuse to think about alternativeperspective, convince themselves that it is only right, harm people whoquestion back, wage wars, convert and kill people. Religion is the opium of the masses. Karl Marx Q8 Whatinteresting facts do you know about stomach acid? A8 JerryJoo A Lover of Interesting Readings ~ Translator onQuora July 23 In the past, peoplethought of the stomach as a sterile organ because of the very acidic atmosphereof the stomach. The pH of stomach acid can even go below 2 But it turns outthat there are organisms that can adapt to this very acidic stomach condition.Yes, this is one of them, Helicobacter pylori. Helicobacter pyloriis a bacterium that can cause gastritis. Helicobacter pylori can enter our bodythrough contaminated food or drink. You can also enter because your hands arenot washed clean after using the toilet. How canHelicobacter pylori live in a stomach with a very acidic pH? Helicobacter pylorican produce the enzyme urease in its cytoplasm. This urease enzyme will helpconvert urea into ammonia and carbon dioxide. Because ammonia has an alkalinepH, so it can neutralize stomach acids that enter the Helicobacter pylori cellsand neutralize the environment in which they live. The urea used to makeammonia comes from outside the cells of Helicobacter pylori. In addition,Helicobacter pylori's helical cell shape makes it easy for these bacteria topenetrate the gastric mucosal layer whose pH is not too acidic and they canstay there. So why don't theorganisms that enter the stomach die? The simple answer is that they have aspecial adaptation mechanism to survive in a very acidic stomach. And besidesHelicobacter pylori, there are also other bacteria that can live in thestomach. Examples are Prevotella, Streptococcus, Veillonella, Rothia andHaemophilus bacteria. These bacteria are also present in the stomachs ofhealthy people. Helicobacter pylori infection can affect the diversity of thebacterial population in our stomach. The interestingfact is, the acid in the stomach is very strong but there are some bacteriathat can live there. Q9 Arethere any tasty South Indian recipes to make for overcooked rice? A9 RukminiHindupur A southie related with Punjab June 19 My father owned afew acres of agricultural land in his native village which was very close tothe city of Hyderabad. So along with hisjob in the police department, he used to grow paddy. So, we used to eatthe rice that came from our land. My father being a part time farmer used toprefer the short duration, thicker variety to grow. And the rice from the newlyharvested crop, that too thicker variety, was a tricky customer to be cooked. Asmall delay in draining the starch water from the cooking rice would result ina white, mushy mass of over cooked rice. Usually I used toget the duty of cooking rice for dinner right from the age of fifteen orsixteen, for a family of seven members. May be around a kilogram or so of riceeveryday. I invented a newmethod to escape from the scorn of my mother in case the rice became a softmush while I was given the duty of cooking rice for dinner. I would remove thevessel from the stove, add a spoon or two of table salt and a bit of jeera,stir it well and push it under the counter into a dark corner so that nobodycan notice it. I would cook a fresh vessel of rice, this time carefully. What would I dowith the hidden mass of rice? Next day earlymorning I would carry that vessel upstairs, make thick strings in a noodlemaker onto a saree spread on the terrace. These would dry ina day or two. Dried rice noodles can be stored year long.They are fried in hotoil. They taste great with daal rice or sambar and rice. It was a laboriousprocess, no doubt. But it helped me escape from my mother’s chastisement. And the youthenergy made every job look very easy. Q10 Why can you use chalk to write on theblackboard but not granite?

A3 ChrisCorsi, former Science Teacher (1999-2021)Answered Sun If you’re referringto locations on Earth, it’s because you live on a globe that orbits the Sun,and only about half can be facing the sun at any given time. The globe rotates,or spins on it’s axis, and so when it is day on one side, the other has night.After 10–12 hours, the rotation causes the reverse, so YOU have night and theother side has day. 2ND ANSWER-Sarah Sharma, StudentAnswered June17 There is day in onearea of the earth and then night in another because earth rotates on it’s axis.So,the part of earth which is towards sun, has daytime and then it keeps onchanging accordingly 3RD ANSWER- Chris Harrington, Bachelor of FineArts from Academy of Art University (2011)Answered22h ago “Why is it day somewhere and night in anotherplace?” Because the Earthis a sphere, and sunlight can only shine on half of it at one time. 4TH ANSWER- Kevin Solari , M.A.F.I.AMathematics from Oxford, Oxfordshire, UK (1977) Answered 18hago First of all Ithought perhaps you were an idiot.
