    The Red Data Book is a public document that records endangered and rare species of plants, animals, fungi, and local subspecies in a given area. The book is maintained by the International Union for Conservation of Nature (IUCN). The Red Data Book is important because it: Provides information for research, studies, and monitoring programs Helps identify and protect species that are on the verge of extinction Helps identify the conservation status of all animals, birds, and other species Helps protect species that are lost, harmed, or not able to continue their life cycle Helps conserve species on the verge of extinction The Red Data Book was created to protect species that are on the verge of extin

    This substance is added to the gas when it leaves the main storage terminals. This substance is added in order to detect its leakage of LPG at the household level in order to save from fire accidents. Hence, the strong smelling substance added to LPG is ethyl mercaptan

    Garima Chandurkar 2 weeks, 4 days ago

    Ethyl mercaptan is a strong smelling agent added to LPG cylinders to detect leakage. As we all know, LPG is very dangerous, because if it leaks, it can cause terrible fires and devastating explosions. To avoid this, Ethyl Mercaptan is added to the gas, which possesses that strong odor of rotten cabbages

    ANSWER
    1. Assertion -Eukaryotic cells have membrane-bound organelles. Reason -Prokaryotic cells lack membrane-bound organelles .     2. Assertion -Tin cans, used for storing food, are made by electroplating tin on iron.  Reason -Tin is more reactive than iron. Thus,food does come in contact with iron and is protected from getting spoiled.   3. Assertion-  In the summer season the frequency of watering is lower in plants. Reason-  It is due to the increased rate of evaporation of water from the soil and the leaves.   4. Assertion - It is difficult to carry a bag with narrow straps as compared to carry the bag with broader  straps. Reason- When the same force acts over a small area its effect is more .   5. Assertion- A ball rolling along the ground gradually slows down and finally comes to rest.  Reason-  This happens due to the force of friction between the ball and the ground.   6.  Assertion-  We apply water between the moving parts of a machine to increase the efficiency of the machine.  Reason - lubricants applied on the surface of the moving part reduces the friction.   7. Assertion - We do not slip when we walk on a wet floor.  Reason-  The water forms a thin layer between the feet and the floor and decreases the friction.   8. Assertion-  legumes revive the soil fertility.  Reason - Microbes in the root nodules of leguminous plants fix the atmospheric nitrogen and increase the fertility of soil.   9 Assertion -The bubbles of gas may be formed on the electrodes during chemical reaction . Reason-  The passage of an electric current through a conducting solution causes chemical reaction.   10. Assertion -The average temperature of the Earth's atmosphere is gradually increasing is called global warming . Reason-  The gasses like nitrogen oxide and water vapors also contribute towards the effect called greenhouse effect.   11. Assertion- Copper does not react with dilute hydrochloric acid even on heating but it reacts with sulphuric acid.            Reason - Metals generally do not react with acids.
