Why insects called jugnu glow in night only?? It is ques of Ch-1.Please give me answer. |
|
Answer» Yes !! ? r u confirm AYUSH? The compound is called luciferin. 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. ... They eat so many fireflies that they themselves begin to glow. They glow always ...they have particular cell which emits light when they breathe in . but due to sunligjt their light cannot be seen in day . and they twincle because they have wings which covers that cell and that wings when spreaded then we see light and when they are closed light disappears |

How could Modern periodic table remove anamas of mendleev periodic table ? |
| Answer» 1) Isotopes of an elements occupy same position in the periodic table due to same atomic number.2) There is a logical separation of elements into subgroups.3) It is based upon the fundamental property of an element i.e. atomic number.4) In the Modern Periodic table elements are arranged in the increasing order of their atomic number, removing the anomaly regarding certain pairs of elements in Mendeleev\'s periodic table.5) Atomic number of cobalt is 27and nickel is 28. Hence cobalt will come before nickel even though its atomic mass is greater. | |

Give reasons..Use of synthetic detergents cause pollution of water |
|
Answer» The main disadvantage of synthetic detergents is that some detergents are not biodegradable and hence cause water pollution in lakes and rivers after accumulating there.\tSynthetic detergents are non-biodegradable. So, these remain in water bodies for a long time and make water unfit for drinking by aquatic animals.\tSynthetic detergents also cause rapid growth of algae in water bodies like rivers and lakes which leads to reduction of oxygen in water bodies.\tDue to reduction of oxygen in water the aquatic animals feel suffocation and can die. They are non-b..iodegradable |

How life is originate from inanimate matter |
| Answer» A British scientist, Haldane, suggested that life originated from simple inorganic\xa0when the earth was formed, it was a hot gaseous mass nitrogen, oxygen, carbon, hydrogen, etc. These elements like water (H2O), carbon dioxide (CO2), methane (CH4), molecules. He believed that containing elements such as combined to form molecules ammonia (NH3), etc. After the formation of water, slowly the earth surface cooled and the inorganic molecules interacted with one another in water to form simple organic molecules such as sugars, fatty acids, amino acids, etc. The energy for these reactions was provided by solar radiations, lightning, volcanic eruptions, etc. This was proved by the experiment of Stanley L. Miller and Harold C. Urey in 1953. They took a mixture of water (H2O), methane (CH4), ammonia (NH3), and hydrogen gas (H2) in a chamber and sparks were passed through this mixture using two electrodes. After one week, 15% of the carbon from methane was converted into amino acids, sugars, etc. These organic molecules are polymerized and assembled to form protein molecules that gave rise to life on earth. | |
