                                      THE BASIC BUILDING ELEMENTS FOR LIFE

In the body of living organisms, many elements are found in different quantities. In them carbon, hydrogen and oxygen have great importance. The human body also constitute these three elements. These elements combine to form organic compounds such as proteins, carbohydrates and lipids. All these compounds work as building material for the bodies of living organisms e.g meat, pulses, fats, cooking oil, sugar, wheat etc                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              


                                                                Carbon                                                                                                                                              

Carbon is one of the essential part of all living things on t his planet. Small quantities of carbon are found in the earth crust as the free element. Carbon is an important element of natural compounds such as natural gas. Petroleum and wood etc. carbon is also present in  the food you eat. The  food containing carbon, hydrogen and oxygen are either carbohydrates (starch, sugar, cellulose) or fats (butter, oil) white the food containing carbon, hydrogen oxygen, and sulphur or nitrogen are proteins (meat, fish). All the plant life is also made up of compounds  containing carbon, hydrogen, and oxygen. Other carbon containing compounds are silk, soap, alcohol, plastic etc.                                                                                                                                                                                                                                                                                                              


                                                                            Hydrogen                                                                                                                 

                                            Hydrogen is an essential part of water (H O) and therefore                                                                          important for all living things. other than this it is found in                                                                          natural gas. It is most common element in the universe, for                                                                      example the sun is a huge white hot ball consisting almost                                                                          entirely of hydrogen.        


                                                                             

                                                                                  Oxygen 

                                         Oxygen is a colourless, odourless gas which is slightly soluble in                                                               water. fish and all form of aquatic life rely on this property. it is the                                                           major constituent of air. The various organic compounds containing                                                           oxygen are glucos, sugar cellulose, fats, proteins etc.                                                      

                                                Importance of Carbon, Hydrogen and Oxygen                                                  

                   You have already studied that carbon, hydrogen and oxygen play important role 

                    In the living organisms.

The Similarities and Differences Between the Sun and Moon

  The Similarities and Differences Between the Sun and Moon The sun and the moon are the two most prominent celestial objects in Earth’s sky. They affect the daily lives of people in significant ways but are very different in their characteristics and effects on the solar system and the Earth. Both of these bodies have been the subjects of extensive scientific research, as well as myths and tales across the ages. Measurements of Time Both the sun and the moon serve as bases for systems of time measurement. The moon is the Earth’s only natural satellite and is the basis of the month on modern calendars. The moon takes 27.3 days to fully rotate around the earth. The sun, around which the Earth orbits, is the basis of the calendar year and day. The sun itself rotates within a period of about 25 days. How They Were Formed The moon and sun are both bright round objects in the sky. Indeed, viewed from the Earth's surface, both appear as similarly sized disks. That said, however, they are...

What Are the Two Planets That Don't Get Solar or Lunar Eclipses?

  What Are the Two Planets That Don't Get Solar or Lunar Eclipses? As Earth and the moon revolve around the sun, they periodically align with the sun in such a way that Earth moves into the moon's shadow and vice versa. Known as eclipses, these are spectacular events for observers on Earth. But they cannot occur on Mercury or Venus: Neither planet has a moon. Eclipses on the other planets in our solar system are possible but probably different than those on Earth. Mercury The first planet in the solar system, Mercury, is closer to the sun than Earth by more than half. From Mercury's surface, the sun appears three times as large as it does from Earth. If Mercury had a moon, it would have to be large enough to cover that disk for observers on the planet's surface to experience a solar eclipse. Such a moon, unless it were very close to the planet, would probably have to be larger than Mercury itself. Thirteen times every century, Earth falls into Mercury's shadow as it...

Physical Activity for Adults

Image
                   Physical Activity for Adults Physical activity plays an important role in both physical and mental health. People who are physically active tend to live longer, healthier lives. Active people are more productive, and more likely to avoid illness and injury ¹ . Whether it’s dancing, exploring, sports, or working out at the gym, safe and regular physical activity will keep the body moving and the heart pumping to provide immediate and long-term health benefits. At least a minimum of 30 minutes physical activity a day can: Lower risk of heart disease Lower cholesterol Lower blood pressure Lower risk of Type 2 diabetes Help manage weight Improve endurance, strength, flexibility Build stronger bones, muscles and joints Lower risk of osteoporosis  Reduce risk of falls Boost energy and mood Improve sleep On the other hand, a lack of physical activity can increase risks of developing preventable conditions, such as: Anxi...
