#First organic compond made by human

Image
    In earth 's crust carbon is 0.02% and found in form of minerals. Atmosphere has 0.03% of carbon dioxide . All living structure are carbon based . A Vital Force Theory was given by Berzelius in 1815 .  According to Vital Force Theory,  organic compounds must have their origin in living organisms and could never be synthesized from inorganic material . This theory is known as the Vital Force Theory. But the end of this theory when Wohler formed a urea (Organic compound) in a Lab from heating of Ammonium cyanide . NH 4 CN → CH₄N₂O (urea) . In after , Acetic acid Methane formed in a lab .

  What is immunity?  Ans- Immunity is a defense mechanism against infections of our body means immune system  kills bacteria and virus (any harmful germ)  and protect our body and to keep healthy our body that is called immunity.  #Below the audio file you can listen too... https://drive.google.com/file/d/1wLQlJRGv8tEobKWk4XFS3MnroAQ-o217/view?usp=sharing  How to work immune system? Ans-  Immunity system is combination of immune cells and proteins. some immune cells is work non stop like Natural Killer  , Macrophages and  some work specific like T-cell and B-cell and proteins work similarly.           When the body sense invader substances the immune system works to recognize the invader and how to get rid of them. Natural killer(NK) kills only the invader substances like bacteria or virus and macrophages kills and identify the bacteria or virus and this cell informs to the T-cells. T-cells activate the B-cells...

Application of Scattering of Light in Daily Life ,Class - 10(Physics)

 Question -  Why Clouds are White?    Answer :- Clouds are made of water droplets of different size. These different sized droplets are scattered in different colours for example , The tiniest droplets scatter more  blue light than other colours .The droplets of size greater than the tiniest droplets scattered more green light and the largest droplets scattered more red light. As, all the colours are scattered by the droplets in the clouds , so the result light is white. hence , clouds appear white. White Clouds  Question:-  Why danger signals are of red colour?  Answer:-  When light falls on the signal , all colours are scattered  more than that of red colour , so the red colour suffering least scattering remains confined around the signal , which in turn illuminates the signal significantly. Thus the danger signals can be seen from very far off distances. Moreover , among all colours ,Red colour or red light is scattered least by smoke...
