                 ☔    Precipitation    ☔ What is precipitation ? Precipitation means falls of water , snow , solid , Iiquid state from clouds to ground . 70.8 % part of the earth's surface is full of water .  The distribution of this water is very uneven . At , some places , the water storage is limited while it is ample at other places . We see and experience the different forms of condensation . These forms of condensation occur due to water vapour in the atmosphere . As the atmospheric conditions change , we see changes in the forms of condensation . On winter mornings , we find dew which are falled on leafed and all other objecta which were under sky at night . In areas located at higher altitudes , snowfall occurs ;  while it rains in other places .  Some places experience dense fog while some places experiences hailstones suddenly and face crop destruction .  Rainfall  :-  1) We generally get water in the form of rainfall .  2) The temperature of the a

             ✊    Acupressure Points  👊 Our Body is full of a Complex System in that we have muscles , bones , blood and nerves , tissues . Our internal body parts are involuntary , and our external body parts are voluntary . We can't do exercise of our internal organs like brain , heart , liver , stomach , lungs , throats , hormonal glands and most of the internal organs . So we can do exercise by the connection of the nervous system by acupuncture the hands and legs and many other external parts . See this image for exercising internal organs  :-  By Acupuncturing all of the whole hand our internal exercise will be well done going on . Please do this for healthy health ....👍

      🌳    Co-ordination in Plants   🌳 Plants do not have systems like the nervous system or muscular system of animals .  Then , how do plants bring about movements ?  In plants , movements are mainly in the form of responses given to the stimuli . Movement or growth of any part of the plant in response to an external stimulus is called 'tropism' or 'tropic movements' . The shoot system of any plant responds to the light stimulus that is it grows towards the source of the light . The movements shown by plants towards the source of the light is called 'Phototropic Movement' . The root system of plants responds to stimuli like gravitation and water .  These responses are called 'gravitropic movements' and 'hydrotropic movement' resectively . Movement shown by plants in response to specific chemicals is called 'chemotropic movements' .  For example , the growth of the pollen tube towards the ovule . All the above - mentioned m

Co-ordination   What is Co-ordination ? Several different organ systems function in multicellular organisms . Their life goes on smoothly if there is co-ordination between this different organ systems or organs and the stimuli in the surrounding . Depending upon this , we can say that systematic regulation of different processes can be called control and bringing about the different processes in the proper sequence can be called co-ordiantion . If any activity in the body is to be completed succesfully , proper co-ordiantion between different systems and organs participating at different steps of that activity is necessary . If due to lack of co-ordination or some other factor , there is confusion at any step the activity may not get completed . There should not be any randomness at any step . There needs to be proper co-ordination between internal activities of the body resulting from various factors like body temperature , water level , enzyme-level , etc .  S

Sonography   What is Sonography ?  Sonography technology uses ultrasonic sound waves to generate images of internal organs of human body . This is useful in finding out the cause of swelling , infection , pain , etc . The condition of the heart , the state of the heart after a heart a heart attack as well as the growth of foetus inside the womb of a pregnant women are studied using this technique . This technique makes use of a probe and a gel . The gel is used to make proper contact between the skin and the probe so that the full capacity of the ultrasonic sound can be utilized . The gel is perfectly applied to the skin outside the internal organ to be studied . High frequency ultrasonic sound is transmitted inside the body with the help of the probe . The sound reflected from the internal organ is again collected by the probe and fed to a computer which generates the images of the internal organ . As , this method is painless , it is increasingly used in me

                          🎷    Echo   🎷 ⚫ So , What is an Echo ? You must have visited an echo point at a hill station . If you shout loudly at such a point , you hear the same sound just after a little while . This sound is an echo . An echo is the repetition of the original sound because of the reflection by some surfaces . In order to be able to hear the original sound and its reflection distinctly , at 22°C . ⚫ What must the minimum distance be between the source and the reflecting surface ?  At 22°C , the velocity of sound in air is 344 m/s . Our brain retains a sound for 0.1 s after starting from the source to get reflected and come back to us .  Thus , we can determine the minimum distance between the source and the reflecting surface . Distance =  Speed  ×  Time .                 =  344  m/s   ×   0.1 sec                 =  34.4 m . Thus , to be able to hear a distinct echo , the reflecting surface should be at a minimum distance of half of 34.4 m  that is  17.2 m

      ⚫  Excretion in human beings  ⚫ 1)  There are different organs system in the human body to bring about the different life processes , such as the digestive system for digestion of food , respiratory system for digestion of food , respiratory system for respiration , etc . 2)  The process of digestion leading to energy production is an important process of our body . 3)  Various waste materials are formed during this process . 4)  Removal of these waste from the body is very important and it is the excretory system that carries out this function . 5)  The human excretory system consists of a pair of kidneys , a pair of ureters , the  urinary bladder and the urethra .  6)  Urine is formed by the kidneys by separating the waste and unwanted excess substances from the blood . 7)  The two bean-shaped kidneys are situated one on either side of the vertebral column , on the posterior side of abdomen . 8)  The functional unit of the kidneys that performs the basic function of

Endogenetic  Movements Endogenetic Movements are the movements which occurs naturally , that are movements occurs inside or outside of earth's crust . Various natural events occur on the earth from time to time e.g. floods , storms , snowfall , extreme rainfall , etc.  Similarly , because of the movement below the earth's surface , natural events like earthquakes and volcanic eruptions occur .  For organisms living on earth , these events are disastrous . There is loss of life and property because of natural calamities .               ⚫    Nepal Devastated  ⚫ Powerful earthquake devastated Nepal , nearly 1500 killed . In Kathmandu , on 25 April (PTI) A powerful earthquake measuring 7.9 on Ritcher scale struck Nepal on 25 April . 1000 people were injured in the disaster . The quake and a series of serious aftershocks delivered a severe blow to Nepal. The tremors were also felt across vast streches of east and northeast India. It was also felt in China

Top 5 superstitions in India , and scientific reason . Superstition no.  1 A black cat crossing road when we are going ahead through the road in front of us , then we must change the road for not impacting on our work we are going for complete work outside . Science :-  That superstition is crazy !! That black cat is an poor animal which can't effect in our work . Superstition no. 2 Don't step on a lemon which is thrown on road , which can cause you entering a ghost in our body , which was inside lemon . Science :-  A lemon is lemon how one can get entering of ghost . Superstition no. 3 Tie the lemon-mirchi for a new car for not getting accident . Science :- An accident can cause due to some imbalance or mismanagement of driving. Superstition no. 4  No cutting of hairs on Saturday . शनि  देवा चा प्रकोप   Science :-  A long span of years ago there were only two barbers in one whole village so they won't get time for rest so they start
