CULTURAL QA 03-2022-08 BEING A COMPILATION THERE MAY BE ERRORS
Q1 What is the world’s most widely usedvegetable? A1 Lucia Garcia AWorked at Hospitals Fri Onions are the most eaten andcultivated vegetables in the world.Onions have been eaten around the world for more than 5,000 years. Accordingto the United Nations Food and Agriculture Organization, at least 175 countries aroundthe world grow onions, twice as many as wheat. Onions are arguablythe most popular vegetables in the world. Theannual output of onions in the world exceeds 90 million tons, and the plantingarea ranks first. China,India, the United States and Egypt are the major onion producers in the world. Onionsare not only delicious, they are also very nutritious. In Europe and the United States,onions are known as the "Queen of Vegetables". Onionsare rich in nutrients, such as vitamin C, vitamin B6, dietary fiber, folicacid, and minerals such as calcium, magnesium, sodium, potassium, selenium, andphosphorus. Mostimportantly, onions contain two special nutrients: quercetin and prostaglandinA, these two special nutrients make onions have many health benefits thatcannot be replaced by other foods. Quercetinis a natural flavonoid that can effectively scavenge harmful free radicals inthe body, protect cells, and delay the aging process of cells. Inaddition, quercetin can inhibit the activity of cancer cells and prevent thegrowth of cancer cells. Studies have shown that eating onions regularly canreduce the incidence of cancer by about 20% to 25%. Among all vegetables, only onion containsprostaglandin A. ProstaglandinA can dilate blood vessels, increase blood vessel elasticity, reduce bloodviscosity, and inhibit the synthesis of cholesterol. Often eating some onionsis very beneficial to the health of cardiovascular and cerebrovascular. Q2 What makes the fluid excreted by theseminal vesicles so alkaline? A2 Ken Saladin Former professor of histology(microscopic anatomy) 22h That’sa good question. Since theseminal vesicle fluid contains citric and ascorbic acids, one might think itwould be acidic. There are presumably some buffers in it. I’d put mymoney on the proteins and phosphates,[1] but nothing came up for me in Google Scholar to explain itsakaline pH. All my sources simply noted that itis alkaline and it neutralizes the acidity of prostatic and vaginal fluids. Ona side note, in the course of researching this, I was surprised to learn thatsome groups of mammals don’t have seminal vesicles—monotremes, marsupials, andcarnivores.[2] Q3 Years ago before humans met sheep, werethey overgrown in wool because no one could shave them? A3 Rik Elswit Musician for 60 years.Professional musician for 55.Feb 18 Nothey were not.Wool growth was a trait that human breeders selected for, and is yet one moreproof for the truth of evolution. Sheep with less wool went immediately into the stew pot,and sheep with thicker wool survived and were allowed to breed. Eventually we bred a species ofsweaters on the hoof that’s totally dependent upon us for survival. Q4 How many seeds does a strawberrycontain? A4 Lucia Garcia Worked at HospitalsUpdated 8h 99% of fruits grow their seeds on theinside, but strawberry seeds adorning the outside of a strawberry. Strawberriesare small, an average-sized strawberry weighs about 25 grams and contains about200 strawberry seeds. Althoughstrawberry seeds are not delicious, but they nevertheless contain many nutrientsmany nutrients your body needs and can be eaten with confidence. Strawberryseeds contain 52.3% dietary fiber, 14.5% protein, 17.9% fat, and minerals suchas calcium, zinc, selenium, manganese, magnesium, copper, strontium, iron, andsodium. Thefat of strawberry seeds is mainly composed of unsaturated fatty acids. Unsaturated fatty acids canregulate blood lipids, reduce blood viscosity, lower cholesterol, and are verybeneficial to cardiovascular and cerebrovascular health.In addition,strawberry seeds contain a lot of dietary fiber. Dietary fiber can improveintestinal flora, promote gastrointestinal motility, keep the intestines open,and eliminate toxins and garbage. Q5 Can broccoli cure breast cancer? A5 Lucia Garcia Worked at Hospitals7h Broccoli is not only nutritious, but also ahealthy vegetable. Inmany countries, broccoli isknown as "a godsend medicine". Eatingbroccoli regularly can help prevent and aid in the treatment of cancer and manychronic diseases. Amongthe cruciferous vegetables, the most frequently mentioned cancer-fighting staris broccoli. Perhapsthe most notable feature of broccoli is that it has anti-cancer effects,especially in the prevention and treatment of gastric cancer and breast cancer. Broccoliis an excellent food source of the natural cancer-fighting compoundsulforaphane(SFN). Sulforaphaneis a common antioxidant and the most potent anticancer plant active substancefound in vegetables.Someexperts believe that eating broccoli 3 to 4 times a week reduces cancer risk by30 to 40 percent. Itis worth mentioning that the anti-cancer effect of broccoli sprouts is muchstronger. Incontrast, sprouted broccoli sprouts had much higher levels of sulforaphane thanmature broccoli. Accordingto the determination, the content of sulforaphane in 100 grams of broccolisprouts is about 260 mg, while the content of sulforaphane in mature broccoliis only about 16 mg. Broccolisprouts are available in some supermarkets and grocery stores in countries suchas Europe, the United States, and Japan. Q6 Is it true that the first humans wereblack or is it Afrocentrism propaganda? A6 Claire Jordan Degree in biology andfolklore; programmer, shop owner, secretary on newspaper1h Thefirst humans were definitely African, no ifs or buts.How black they wereis going to depend in part on how far back you want to define our ancestors ashuman. Once they hadlost their fur and become naked apes they must have been quite brown orthey would all have succumbed to skin cancer and spina bifida, but while theywere still as furry as other apes, we just don’t know. Our closest livingrelatives are the chimps and bonobos: bonobos have black (or rather dark grey)skin under their fur, while chimps are usually a kind of brownish pink. Gorillas are very black,orangutans dark brown. So furry proto-humans could have been any of the colourshumans are nowadays, under the fur. Oncethey were naked, as I say, they would have been some shade of brown. The KhoiSan, who arean ancient group and live near the first home of humans, around Botswana andthe Great Rift Valley, arequite a light golden-tan, almost khaki, so our ancestors may well have been thesame colour. But early humans would havedarkened like toast as they moved nearer the equator. Q7 Why do wives cry after arguments withhusbands? A7 Ratnamala Kamath M'com from KarnatakUniversity, Dharwad (Graduated 1988)Sat Thereare many women who don't cry during or after arguments with spouse. UnfortunatelyI'm not one of them. WheneverI get very angry, hurt or sad tears automatically start flowing from my eyes.I know it compromises my position and makes me appear weak, but I'm unable tocontrol myself. Mostwomen are emotional creatures and when someone hurts them especially someonewhom they are attached or close to, their anger and hurt transforms into tearsand starts flowing from their eyes. This is especially more during PMS. I'm now taking tips from my son on how tonot cry during or after fights and arguments.I have succeeded in controlling myself from crying 2 times. Hopefullywhen I master attachment with detachment I will be able to stop crying alsoduring fights and arguments. Keeping my fingers crossed and waiting forthe day when I can gain mastery over my emotions. It's still work in progressthough. Q8 Today I saw a post where a set of twinshave different complexions. One is dark while the other is albino.Biologically, how is this possible? Is it possible at all? A8 Claire Jordan Degree in biology andfolklore; programmer, shop owner, secretary on newspaper22h Fraternal twins are no more alike thanany other siblings.If fraternal twins come out different colours it just means that one or bothparents are heterozygous at one or more genetic loci which influence skincolour, so that there are a lot if different ways their colour genes could endup combined. The commonest allele (gene variant) foralbinism is very recessive, so in this case it means that both parents arecarrying a single allele for albinism at that locus. Call the allele for full colourC and for albinism ca. On average a quarter of their children will end up C/Cand have full-coloured skin, half will end up C/ca and also have full-colouredskin because C is dominant to ca, and a quarter will have ca/ca and be albino. Ifthe twins are identical twins, it could only happen if there was a somaticmutation very early in embryological development. If the initial embryo hasC/ca alleles, and then at the stage where the zygote has only two cells, one ofthose cells loses its C allele and become -/ca at that locus, and then the twocells split apart and give rise to two different embryos, you’ll get one albinoand one full-coloured twin who are otherwise identical. But if a cell loses itsC allele once there are multiple cells in the zygote, then depending on whenthat mutation occurs relative to when the zygote splits, one or both twins willend up piebald, with mixed patches of colour and albinism. Thiscan happen - I was at school with a girl who was piebald. She was white andquite pale, so usually you couldn’t tell, but when she was sun-tanned you couldsee that she was patched with brown and white like a pony, Q9 Is Pune Metro fully operational? A9 Prasanna Bhalerao Lives in Pune,Maharashtra, India (1980–present)10h No. The Pune metro is not yet fullyoperational.The total length of metro cover is about 32 km over two separate lines orsections (Section A: Swargate to Pimpri-Chinchwad municipal corp (PCMC) - partof it is underground, section B: Vanaz to Ramwadi - fully overground). A small part of Section B, fromVanaz to Garware College, about 4 km was inaugurated yesterday by our PM.Another part of Section A, PCMC to College of Military Engineering (about 6 km)will start pretty soon. ThePune metro is expected to be fully operational (over current route) in anotheryear or two. Q10 Who really built the Great Pyramidof Giza and other ancient Egyptian pyramids? A10 Claire Jordan Degree in biology andfolklore; programmer, shop owner, secretary on newspaper18h Mainly gangs of farmers who weretemporarily jobless while their fields were under water during the annualInnundation of the Nile,overseen by professional builders. They were an early job-creation scheme -they gave the farmers occupation, food and a dry place to sleep while theirfarms were inaccessible. All the above QA are from Quora website on 07-03- 2022.
