What is de-starching ? How is it done |
| Answer» Destarching is the process of removal of all the stored starch of a plant.Plants get destarched when kept in dark for 48 hours because in dark they are not able to produce food by the process of photosynthesis as there is no sunlight available to run this process, so they have to use stored food(starch) in them by this they consume their starch and get themselves destarched. | |

What is refractive and refraction index |
| Answer» Refractive Index:The extent of bending of light rays entering from one medium to another is known as\xa0“Refractive Index”. It is denoted by the letter ‘n’. And can be represented as :n = c/vWhere c = velocity/speed of light of a certain wavelength in the air and v = velocity of light in any medium.\tlaw of refraction also known as the\xa0“Snell’s Law”.Snell’s LawIt gives the amount of bending of light rays. It determines the relationship between the angle of incidence, the angle of refraction and relative indices of given pair of media. It is defined as the :“Ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant for the light of given color and for the given pair of media”.\xa0 | |

Why human hearts have double circulatory system of blood? |
|
Answer» The type of circulation in humans and the other mammals is called double circulation. First our heart pumps blood to the lungs where it gets oxygenated which then comes back to heart and is pumped to the rest of the body parts. Thus blood is pumped two times in our body which is referred as double circulation As blood comes twice in heart is known as double circulation First our heart pumps blood to the lungs where it gets oxygenated which then comes back to heart and is pumped to the rest of the body parts. Thus blood is pumped two times in our body which is referred as double circulation To maintain body temperature. |

What is ohm\'s law explain in simple language ? |
|
Answer» Ohm\'s law gives a relationship between potential difference and the current...See on ncert book for more information... Ohms law states that the temperature remain constant ,the potential difference across the conducting wires directly proportional to the cureent flowing through the wire At constant temperature,the potential difference across the end of the conductor is directly proportional to the current flow through the conductor. Ohm\'s law state that current is directly proportional to potential difference OHM’s law states that under no same temperature, electric current flowing through an ideal conductor is directly proportional to the potential difference across its ends.V ∝ IV = IR, R – Resistance\tResistance is a property of conductor to resist flow of charge through it. Its SI unit is Ohm (Ω).R = V/I, 1 Ohm = 1 Volt/ 1 Ampere At constant temperature current is directly proportional to voltage It shows the relation between the potential difference and current |

Why do star twinkling |
|
Answer» Stars do not really twinkle, they just appear to twinkle when seen from the surface of Earth. The stars twinkle in the night sky because of the effects of our atmosphere. When starlight enters our atmosphere it is affected by winds in the atmosphere and by areas with different temperatures and densities. This causes the light from the star to twinkle when seen from the ground due to atmospheric refraction. because they are hot glowing gases that seems to be twinkling |

What is translocaton of food |
| Answer» Translocation is the movement of nutrients and other materials from leaves to other tissues throughout the plant.\xa0Plants produce carbohydrates (sugars) in their leaves by photosynthesis, but nonphotosynthetic parts of the plant also require carbohydrates and other organicand nonorganic materials. For this reason, nutrients are translocated from sources (regions of excess carbohydrates, primarily mature leaves) to sinks (regions where the carbohydrate is needed). Some important sinks are roots, flowers, fruits, stems, and developing leaves.Translocation occurs within a series of cells known as the phloem pathway, or phloem transport system, with phloem being the principal food-conducting tissue in vascular plants. Nutrients are translocated in the phloem as solutesin a solution called phloem sap. The predominant nutrients translocated are sugars, amino acids, and minerals, with sugar being the most concentrated solute in the phloem sap.Translocation occurs in both upward and downward directions. Ascent of sap occurs largely using simple physical forces like transpiration and root pressure, but translocation is achieved by utilising energy. | |
