 How does Water get inside a Coconut? by a process called osmosis. Over a period of time this creamy tissue turns hard and the remaining endosperm ends up as coconut water. So this is how water ends up inside a coconut. Image of coconut plant   Firstly, roots of the coconut plant absorb water from the soil. This water is then transported to different parts of the coconut plant, some of it reaches the coconut. The liquid which eventually reaches the coconut is referred to as the endosperm. This endosperm acts as the food or nourishment for the coconut's growth. Now, a part of the endosperm gets converted into a creamy tissue and gets deposited on the coconuts inner surface. Coconut 🥥 🌴 water is so much nutritional for human body . We should drink at list one Coconut for weak and you will see a lot of improvement in body. Like 1 )  it boost our energy  2)  reduces blood pressure  3)  reduce dibities  6)  keeps our body hydrated  5) detox...

 A heart attack or myocardial infarction is the complete blockage of blood flow to a part of the heart, causing its muscle cells to die. Image of complete blockage of blood flow A network of blood vessels called coronary arteries continuously supply oxygenated blood to muscle cells of heart to keep them working properly. Coronary Arteries of the Heart However, due to bad lifestyle choices and stress, Image of stress  cholesterol and fats start building in these arteries reducing blood flow to the muscle cells. This buildup is called plaque. Plaque is the main culprit behind most heart attacks. Image of heart attack  When plaque ruptures, a blood clot forms around it causing the artery to get completely blocked. The blood then cannot pass further to that part of the heart. Thus, due to lack of oxygen, the muscle cells in that part die. This condition is called a heart attack.

   If we consume a lot of sugar, then it can lead to serious health problems. For example: Image of sugar  A hormone called leptin tells our brain when to stop eating. However, consuming excess fructose which is a type of sugar can cause leptin resistance, a condition in which our brain does not respond to leptin. Hence, we overeat, resulting in obesity. Moreover, excess sugar is converted into a type of fat called triglycerides. Triglycerides can enter the bloodstream and form fatty deposits or plaques in blood vessels, increasing the risk of heart attack and stroke etc.  Image of heart attack  Excess sugar can even bind to collagen and elastin in our skin, damaging them and thus, making our skin saggy and wrinkly. Image of saggy and wrinkly skin .   Studies have also shown that women who have one or more sugary drinks per day are more likely to develop diabetes. Image of sugary drink. That's why  we need to stop consuming excess  sugar than...

   Onions consist of amino acid sulfoxides.  When we cut an onion, millions of onions cells rupture,  releasing the amino acid sulfoxides along with some special enzymes. Image of onions          These special enzymes react with amino acid sulfoxides to  form a chemical called   Syn-propanethial-S-oxide.  Amino acids sulfoxides  Syn-propanethial-S-oxide This chemical is volatile, that is, it easily evaporates at   normal temperature, forming a gas.         When this gas reaches to our eyes, it reacts with the substance that keeps our eyes lubricated and forms mild sulfuric acid.   This sulfuric acid gives us a burning sensation.   Now, in order to wash off this acid, our lacrimal glands   produce a disinfecting liquid. But when our eyes cannot hold any extra amount of disinfecting liquid, it starts to fall down, making us cry.

        How pearls formed ?   Pearls are the result of a biological process within living sea creatures like an  oyster  as it protects itself from foreign substances. Image of pearls                 An oyster has two shells. Inside the shells, there is an organ called  mantle . Mantle covers and protects all the internal organs of the oyster. Image of pearls                     Whenever any foreign substance like a grain of sand or a parasite makes its way into the oyster and gets stuck in between the shell and mantle, the mantle's natural reaction is to cover that foreign substance to protect the oyster's internal organs. For this, the mantle secretes a mineral called  nacre  around the foreign substance in layers. Over time, layer upon layer of nacre leads to the formation of a pearl.

  Everybody think water has no colour. then  why sea water looks blue. Because water has colour.    Glass of water  When we see glass of water then we can't see  the colour of water.          DOU YOU KNOW WHY ?               We all know range of visible region is  400 - 750 nm. We can see that region through our eyes.            Lets come to the point. Glass can contain very less amount of water. Water absorbe all long wavelength means red, orange, yellow colours and reflect short wavelengths means violet,  blue colours. But That reflection and  absorption of colours is very less in amount means almost negligible reflection occurs. That reflection can't be captured by our eyes. That is why water look transparent in a glass instead of  blue.          Image of sea water    But in case of lakes, sea, water l...

  Everytime when we look up then we see blue sky.                  Do you know, why ?                   That is all happens because of scattering of blue light.  We all know the range of visible region.                     Red, orange, yellow colours have high wavelengths, but they have low energy and frequencies. Because of that low frequencies, that colours can't scatter just like blue and  violet colours. And that is why they travel  lot of distance. Frequencies of colours varies from red to blue and blue to red.              In other hand blue, violet, colours has low wavelengths but they have high energy  and frequencies. And  Scattering of light is totally depend on frequency of colours. Violet and blue colours has high frequencies. our atmosphere contain diff...

  Let's have a look at the advantages of cold showers: Cold shower Firstly , as we are warm-blooded, the sudden sensation of cold water awakens our body, thus making us feel fresh and alert.  Secondly , many scientists believe that when our body suddenly comes in contact with cold water, it sends a jolt of electrical impulses to our brain, helping boost our mood in the process.  Lastly , cold showers may contribute to weight loss as our body might burn more fat to generate heat. Hot showers have the following advantages:            Hot shower Firstly , scientists believe that hot showers lead to the release a hormone called oxytocin, easing anxiety and stress.  Secondly , as hot showers can help clear the nasal passage, they might be beneficial for a person suffering from cold.  Thirdly , hot water can help release tension and stiffness in our muscles.  Lastly , hot water can kill bacteria, thus preventing infections.

   Dry ice is basically solid carbon dioxide and it's  chemical formula  is  CO ₂. The surface temperature of a dry ice block is about  -78 degrees Celsius or -109 degrees Fahrenheit.  This means it is much cooler than ordinary ice which is made up of water. If dry ice comes in contact with our skin, our cells begin to freeze and  die  within seconds, thus giving us severe frostbite. In addition to this, storing dry ice in airtight containers can be  dangerous . Do you know why? This is because dry ice sublimates, i.e., it directly gets converted from solid state to gaseous state. Hence, in airtight containers, the gas produced can build up and exert pressure on the walls of container which can lead to a dangerous explosion. Dry ice is dangerous but it is also useful as cooling agent and to create dramatic scenes in theater by using fog machines . 

Please don't sleep under tree at night.  It is quite harmful.      See, during night you are not able to breathe properly, right? Do you know why? This is because during the day, in the presence of sunlight, plants takes in carbon dioxide and release oxygen in the process of photosynthesis. That is why production of oxygen is more than the production of  carbon dioxide during daytime.  Hence, if we sleep under a tree during daytime, we may get a  good amount of oxygen, thus giving us a nice sleep. However, at night, plants do not perform photosynthesis due to the absence of sunlight.  But respiration still goes on.  Hence, as compared to oxygen, the proportion of carbon  dioxide around the trees is more. Thus, if we sleep under a tree at night, we may feel suffocated due to lack of oxygen. Moreover, inhalation of excess carbon dioxide is harmful to  human beings. Therefore, it is not good to sleep under a tree at night.

 After  alpha , beta, gamma , and  delta plus  variant of covid-19 the new variant of covid-19  omicron  has came in market and has already started to spread all over the world.  Origin of omicron :   According to recent information County  Botswana  of the South Africa was place place where first case of omicron found. But it's not true actually south Africa was the one who informed all world about new variant omicron. That was south africa goodness.  After all this time, now know we know where omicron really came from. Now Netherland, Belgium and Germany revealed that omicron was already present in our country's before south Africa. According to Netherlands on November 19th they took some samples from Corona affected people and that's when they realized there is new variant of covid-19 and now they have announced  lockdown  in Netherland. In Netherland theaters, Bar, restaurants, will be close after 5 o.clock . That's me...

 Our teeth basically consist of three parts. The outermost part is enamel. Enamel is white in color. Beneath the enamel, there is dentine. It is yellow in color. Then comes the part called pulp, which has blood vessels and nerves. Now, when we drink or eat acidic fruits and beverages like lemon, orange juice, soft drinks, etc., they erode or wear away the outermost part called enamel and start exposing the yellow color dentine and thus, making teeth appear yellow. However, did you know that some people's teeth are naturally yellowish? This is because in such people, the layer of enamel is thin, causing the yellow color of the dentine to appear more clearly and thus, making their teeth appear naturally yellow.
