How do Fireflies Glow?

   Image result for how do fireflies light up
  Fireflies or lightning bugs make light within their bodies. This process is called bioluminescence and is shared by many other organisms, mostly sea-living or marine organisms.
      To do this, the fireflies contain specialized cells in their abdomen that make light. In this cell When oxygen combines with calcium, adenosine triphosphate (ATP) and the chemical luciferin in the presence of luciferase, a bioluminescent enzyme, light is produced.    
     As air rushes into a firefly’s abdomen, it reacts with the luciferin, and a chemical reaction gives off the firefly’s familiar glow. This light is sometimes called “cold light” because it generates so little heat. 
   Some experts think the firefly’s flashy style may warn predators of the insect’s bitter taste.Male fireflies also light up to signal their desire for mates – and willing females attract the males with flashes of their own.But not all the flashing of fireflies is motivated by romance.So the next time you see a firefly, keep in mind that its flickering isn’t just a wonder of the night. It’s also a unique love language … that can be deadly.

Oxygen can Killing us slowly!!!

 Hey my friend , be relax ,close your eyes for a moment and FOCUS ON your BREATHING. Breathe deeply. Then release the air from your lung .Do it many times .Of course It feels great .so oxygen brings life .97 % of the oxygen do this miracle for us  and used to produce energy. .BUT remaining 3 % of the ( hungry) Oxygen having Dark side and produce free radicals.           These free radicals can eat our body cells day by day....showing symptoms when we get old. LIVING TOO SHORT;DYING TOO LONG Scientific research shows that these free radical damage is the underlying causes of almost every chronic degenerative diseases known as diabetes ,cancer, macular degeneration and arthritis. If it is in your eyes ,you could develop cataracts or if it is in your blood vessels, you could have a heart attack or If it is in your joints ,it could develop arthritis.             Causes of free radical damage is       ...

During summer the Eiffel Tower is taller.How?

Thermal Expansion. What is thermal expansion?       Imagine you have a rod. This rod can be made of metal, plastic or wood. The length of your rod changes proportional to the environmental temperature. We know that fluids expand in their volume when they are heated.Solid materials can expand as well.        So the height of the Eiffel Tower is 324 meters on average-changes depending on the season. When the hot summer sun beats down on it, thermal expansion causes the metal to grow. The tower can swell in height by as much as 15 centimeters (6 inches). But once the hot sun goes down, the expansion decreases.Not only towers but bridges can expand in their length too. Here is the use of expansion joints essentials. These little gaps allows brides to expand in summer without destroying the material due to the acting force. Without these expansion joints bridges might get seriously damaged over time.

Why heavier objects do NOT fall faster than lighter objects?

    How fast something falls due to gravity is determined by a number known as the "acceleration of gravity", which is 9.81 m/s^2 at the surface of our Earth. Basically this means that in one second, any object's downward velocity will increase by 9.81 m/s because of gravity. This is just the way gravity works - it accelerates everything at exactly the same rate. What you may be getting confused by is the fact that the force of gravity is stronger on heavier objects than lighter ones. Another way of thinking of this is to say that gravity has to pull harder on a heavy object than a light one in order to speed them both up by the same amount. However, in the real world, we have things like air resistance, which is why sometimes heavy things do fall faster. For example, if you drop a feather and you drop a rock, the rock will land first since the feather is slowed down more by the air. If you did the same thing somewhere where there is no air, the feather and the roc...
