Quora answers need not be 100% correct answers. Compiledand posted by R. Gopala Krishnan, 80, on 25-09-2023. Q1 Whatevolutionary advantage does a hyena have by having longer front limbs and muchshorter hind limbs? Or is there no advantage, but rather simply nodisadvantage? A1 Gary Meaney, author of Zoology'sGreatest Mystery (2022)18h Contrary to popular belief, theforelegs of hyenas are not significantly longer than the hind legs! It’s easy to see where this idea comes from,particularly when looking at a spotted hyena: Butit is not the case. If we strip back the layers of soft tissue and look solelyat the skeleton of the hyena, we discover that the two pairs of limbs are virtually identical in length.If anything, the hind legs canbe ever so slightly longer. It’ssomething else entirely that creates the sloping appearance of the hyenasilhouette. The vertebrae of the thoracic spine (upper back) have extremelylong protrusions, which we call spinous processes. These processes serve as anchor points for aset of utterly massive neck muscles. And why do they need these? Well, all hyenassuffer constant pressure from lions, and to a lesser extent, other carnivores.When they have made a kill or found a carcass, one can be sure that theserivals will soon be on the scene, ready to drive the hyenas away. Because of this, it helps to eatfast - a single spotted hyena can scoff an entire gazelle in two minutesflat! Another useful strategy is to carry the prey away to a safer, moresecluded location. Carryingsuch a heavy prize at such a distance from the fulcrum requires an absurdamount of strength, sohyenas’ have gigantic neck extensor muscles. All this thickmusculature, in combination with the long, bony spines it attaches to, createthe illusion that the limbs at the front are longer than the limbs at the back. Theexact same illusion is seen in animals which have huge heads. The Americanbison, for example, has an immense skull and a heavy set of horns, which it hasto carry around all day. Furthermore, this head must withstand devastatingforce during head-butting competitions over territory or mates. Bisons havethat same sloping-backed appearance as hyenas: But again it’s the spinous processes,not the forelegs, that create the profile.They need to support incredibly large muscles, which in turn need to lift anincredibly large head. Thesame goes for the magnificent muskoxen of Arctic lands, and various otherbovids. Do note that everything I said above abouthyenas applies only to spotted hyenas, striped hyenas, and brown hyenas. The aardwolf, the oddball of the family,leads a very different lifestyle, and as such has very different anatomy. It’ssmaller than a beagle, and eats only termites. It may slurp up 300,000 of themin a single night! Ilike to think of the aardwolf as the handbag dog of the hyena world… Anyway,now we’re really getting off track. I hope you all enjoyed this answer, guys,thank you for reading! I have just started college, so life isgetting busy again,but I intend to post on Quora as much as possible nevertheless!Your support is much appreciated. As always, have a great day! Q2 Whois the first known engineer? A2 Silk Road, AI Expert Sep 19 Imhotep Many may already know this, but he wasalso a physician, a priest, a scribe, and a vizier to the pharaoh Djoser. TheStep Pyramid was originally intended to be a mastaba, a rectangular tomb withsloping sides.But Imhotep had a better idea: why not stack several mastabas on topof each other, creating a staircase to the sky? And why not use limestoneinstead of mud bricks, making it more durable and impressive? Andwhy not add a complex of temples, courtyards, and underground chambers aroundit, making it a sacred city for the dead? Andwhy not carve his name on it, making sure everyone knows who did it? The result was a masterpieceof engineering that inspired generations of pyramid builders after him. TheStep Pyramid stands at 62 meters (203 feet) high, with a base of 109 by 125meters (358 by 410 feet). Itconsists of six steps, each smaller than the one below it. It was covered withpolished white limestone, which must have gleamed in the sun. Itwas surrounded by a wall that enclosed 37 acres of land. It contained more than5 kilometers (3 miles) of tunnels and chambers, some of which are stillunexplored. Imhotep was not only anengineer, but also an innovator. He is credited with being thefirst to use stone columns to support a building. He also devised a methodto transport and lift huge blocks of stone without cranes or pulleys. He used wooden sledges, ramps,levers, and ropes to move the stones along the Nile and up the pyramid. Healso used wooden molds to shape the stones into regular blocks.He was a master of geometry,astronomy, and mathematics. Imhotepwas revered by the ancient Egyptians as a god of medicine and wisdom. Hewas also respected by the ancient Greeks and Romans, who called him Imouthesand associated him with their gods of healing and knowledge. Heis considered the father of medicine by some historians, as he wrote severalmedical treatises that were used for centuries. He is also considered the patron saintof architects and engineers by some modern organizations. Imhotepwas the first known engineer, and one of the greatest minds of all time. Q3 Whydo people usually get cancer only in one area in their body? A3 Narayana Health, Health for all. Allfor health.11mo Canceris one of the most deadly diseases that have become prevalent recently. Though many advancements have happened in the oncology forte,scientists are still trying to find the right cure for cancer in advancedstages. Canceris a genetic disease. A genetic alteration that causes uncontrolled growth anddevelopment of cells cause cancer.Abnormal growth can be benign and malignant. A noncancerous(benign) tumor can occur anywhere in the body due to abnormal cell growth. Abenign tumor is an abnormal but noncancerous collection of cells. It can formanywhere on or in your body when cells multiply more than they should ordon't die when they should. It grows slowly, has borders, and doesn't spread toother body parts. Malignantare the ones that have cancer cells and may spread to other body parts, whilebenign growths do not. Cancer cells break away from the originsite and can travel to other body parts and may be present in the lymph nodesor other body organs, thus impacting their normal functions. Cancercan occur in any body part as genetic alterationsmay impact cells of any body part. As each body organ has a different geneticrepresentation, alteration in them strikes only specific body parts. Cancergenerally starts with the genetic changes moderating cells of a particular bodypart. Therebycancer usually occurs in only one area of people's body. But, in later stages,it can also spread to other body organs.

A4 Sonu J S, Electrical Engineer &Physics Tutor, LED Trainer (2013–present)5y Postpaid customer’s recharge amount permonth is fixed. Even if the customer is not using call/data they need to pay the fixedamount. So company can expect it as an assured income. Prepaidcustomer may or may not recharge their account. Even if they recharge, theamount may vary (it canbe as low as 10rs or may be as high for eg 1000 or 2000 or depending on need) Soas the amount from postpaid customer is a assured amount companies prefer morepostpaid customers Note(don'tthink postpaid is better for user.. read reason below) : As companies have more prepaid customerthan postpaid customer's more attractive and economic offers comes in prepaidplans. Foreg as per may 2018 airtel offers postpaid plan of Rs 399 for 1 month with 20GBdata & free voice but for prepaid plan of Rs 399 we get 70GB & freevoice for 70 days (approx 2.5 months) Q4A Whydo telecom operators want us to shift from prepaid to postpaid and remain inpostpaid? A4A Robin Raina, Works at Airtel (company)7y The main reason to do this is becausetelecom providers consider postpaid customers as the main and consistentsource of income. Prepaidcustomers are not traceable as far as recharge id concerned. A prepaid customer can recharge with Rs 100 this month and may notrecharge at all for next 2 months. So apart from initial revenue,consistent monthly revenue is considered good for telecom operators. Onthe other hand a postpaid customer is taken as a consistent revenue generatoras if he doesn't even calls or texts, he is still liable to pay the monthlyrental for his postpaid customer. My note- Banks consideronly fixed deposit as asset, not SB accounts irrespective of balance- Ananalogy. Onaccount of this banks offer more interest on Fixed deposits and meagre interestfor savings balance irrespective of the balance amount.Banks offer more interest than SB for Fixed deposits even for a month on thisaccount, Q5 Whowrote Mahabharata, Ved Vyas or Lord Ganesh? A5 Black Bird, Mcom in Cost and WorksAccounting & Cost and Works Accounting, Vidya Pratishthan's Arts ScienceAnd Commerce College, Baramati, Pune (Graduated 2021)9h Accordingto Hindu tradition and mythology, the Mahabharata, one of the most significantand extensive epic poems in the world, is attributed to the Vyasa. Vyasa is consideredthe author of the Mahabharata and is credited with composing and compiling thisepic text. Thestory of Lord Ganesha's involvement in the writing of the Mahabharata is awell-known legend within the epic itself. According to the legend, Vyasa wanted to dictate theMahabharata to someone who could write it down without pause. He chose Lord Ganesha, known for hiswisdom and knowledge. Duringthe composition of the Mahabharata, Ganesha agreed to be the scribe but imposeda condition. He would write only if Vyasa narrated the epic without stopping.Vyasa, in turn, placed his own condition that Ganesha must comprehend theverses before writing them down. This legendary collaboration between Vyasa andGanesha resulted in the creation of the epic, with Ganesha using his tusk towrite down the verses as Vyasa recited them. While this story highlights the divineassistance of Lord Ganesha in the transcription of the Mahabharata, the epicitself is traditionally attributed to the sage Vyasa, who composed and compiledits verses. -- You received this message because you are subscribed to the Google Groups "Thatha_Patty" group.
