What is immunisation ?give some examples |
| Answer» When the immune system first sees an infectious microbe, it responds against it and then remembers it specifically. So the next time that particular microbe, or its close relatives enter the body, the immune system responds with even greater vigour. This eliminates the infection even more quickly than the first time around. This is the basis of the principle of immunization.Vaccines work on the principle of immunization. Vaccines help a body\'s immune system prepare in advance to fight infectious illnesses and potentially deadly diseases caused by infectious agents or their by-products. Vaccines ‘fool’ the immune system into developing a memory for a particular infection by putting something that mimics the microbe we want to vaccinate against, into the body. | |

What is Fertilizer and which type |
| Answer» Fertilizers are chemical substances supplied to the crops to increase their productivity. These are used by the farmers daily to increase the crops yield.\xa0Types of FertilizersThere are six different types of fertilizers that are mentioned below:Inorganic FertilizersInorganic fertilizers are chemical fertilizers that contain nutrient elements for the growth of crops made by chemical means. The inorganic fertilizers are of the following types:Nitrogen FertilizersNitrogen fertilizers contain nitrogen necessary for the development of crops. Nitrogen is the main constituent of chlorophyll that maintains a balance in the process of photosynthesis. It is also a part of amino acids in plants and constitutes protein. Nitrogen fertilizers improve the production and quality of agricultural products.Phosphorus FertilizerThe main nutrient in a phosphorus fertilizer is phosphorus. The efficiency of fertilizer depends upon effective phosphorus content, methods of fertilizing, properties of soil and crop strains. Phosphorus found in the protoplasm of the cell plays an important role in cell growth and proliferation. The phosphorus fertilizer is beneficial for the growth of roots of the plants.Organic FertilizersOrganic fertilizers are natural fertilizers obtained from plants and animals. It enriches the soil with carbonic compounds essential for plant growth. Organic fertilizers increase the organic matter content of the soil, promotes the reproduction of microorganisms, and changes the physical and chemical properties of the soil. It is considered to be one of the main nutrients for green food. | |

What is vaccination? Write its importance? |
| Answer» Vaccination is the administration of a vaccine to help the immune system develop protection from a disease.\xa0Vaccines work on the principle of immunization.

How does the water kepy6in an earthen pot became cool during summer |
| Answer» An earthen pot (matka) has many small pores. Water seeps out through them and evaporates from the surface of the pot. The energy needed for evaporation is taken from the water kept in the earthen pot. As a result, water kept in earthen pot becomes cool. | |

Why is plasma membrane like CO2 and water move in and out of the cell |
| Answer» The substances like CO2and water move in and out of a cell through the process called diffusion from the region of concentrated region to low concentrated one. When the concentration of carbon di-oxide and water is higher in external environment than that inside the cell, CO2 and water moves inside the cell. When the concentration outside the cell is low but it is high inside the cell, they move outwards. | |

derivations of equations of motion |
|
Answer» v=u+at (1) First equation of Motion:V = u + atsoln.Consider a body of mass “m” having initial velocity “u”.Let after time “t” its final velocity becomes “v” due to uniform acceleration “a”.Now we know that:Acceleration = change in velocity/Time taken=> Acceleration = Final velocity-Initial velocity / time taken=> a = v-u /t=>at = v-uor v = u + atThis is the first equation of motion.—————————————-(2) Second equation of motion:s = ut + 1/2 at^2sol.Let the distance travelled by the body be “s”.We know thatDistance = Average velocity X TimeAlso, Average velocity = (u+v)/2.: Distance (t) = (u+v)/2 X t …….eq.(1)Again we know that:v = u + atsubstituting this value of “v” in eq.(2), we gets = (u+u+at)/2 x t=>s = (2u+at)/2 X t=>s = (2ut+at^2)/2=>s = 2ut/2 + at^2/2or s = ut +1/2 at^2This is the 2nd equation of motion.……………………………………………………………(3) Third equation of Motionv^2 = u^2 +2assol.We know thatV = u + at=> v-u = ator t = (v-u)/a ………..eq.(3)Also we know thatDistance = average velocity X Time.: s = [(v+u)/2] X [(v-u)/a]=> s = (v^2 – u^2)/2a=>2as = v^2 – u^2or v^2 = u^2 + 2asThis is the third equation of motion.\xa0 v=u+at |

What is the process to separate two miscible liquids? |
|
Answer» Sorry it\'s not miscarriages ,it\'s miscible Separation by simple distillation is used in separating two miscarriages liquids. Fractional distillation is used to separate substances who\'sdifference in boiling point is less than 25K Fractional distillation 1.\xa0Miscible liquids :Those liquids which mix together in all proportions and form a single layer are called miscible liquids.Ex.\xa0 Alcohol and water are miscible liquids because they mix together in all proportions and form a single layer on mixing. A mixture of miscible liquids is separated by the process of fractional distillation.\xa0Separation by fractional distillation :Fractional distillation is the process of separating two (or more) miscible liquids by distillation, the distillate being collected in fractions boiling at different temperatures. A mixture of two miscible liquids can be separated by the process of fractional distillation. The separation of two liquids by fractional distillation depends on the difference in their boiling points. Fractional distillation is carried out by using a fractionating column.Ex.\xa0 Alcohol and water are miscible liquids. The boiling point of alcohol is 78ºC and the boiling point of water is 100ºC. Since the boiling points of alcohol and water different, therefore, a mixture of alcohol and water can be separated by fractional distillation. The mixture of alcohol and water is heated in a distillation flask fitted with a fractionating column. When the mixture is heated, both alcohol and water form vapours as their boiling points approach. The alcohol vapour and water vapour rise up in the fractionating column. The upper part of the fractionating column is cooler, so as the hot vapours rise up in the column, they get cooled, condense and trickle back into the distillation flask.he more volatile liquid distils over first, and the less volatile liquid distils over later. A mixture of alcohol and water can be separated by fractional distillation.(ii) Separation by a separating funnel :\xa0A mixture of two immiscible liquids can be separated by using a separating funnel. A separating funnel is a special type of funnel which has a stop-**** in its stem to allow the flow of a liquid from it, or to stop the flow of liquid from it. The separation of two immiscible liquids by a separating funnel depends on the difference in their densities.The mixture of two immiscible liquids is put in a separating funnel and allowed to stand for some time. The mixture separates into two layers according to the densities of the liquids in it. The heavier liquid or denser liquid forms the lower layer whereas the lighter liquid forms the upper layer. On opening the stop-**** of separating funnel, the lower layer of heavier liquid comes out first and collected in a beaker. When the lower layer of heavier liquid has completely run off, the stop-**** is closed. The lighter liquid in the upper layer is collected in a separate beaker by opening the stop-**** again.Ex. Water and kerosene oil are two immiscible liquids. So, a mixture of water and kerosene can be separated by using a separating funnel. |
