Write a short note on dialysus |
|
Answer» Dialysis is used for the patient whose kidney is failed. Dialysis is primarily used to provide an artificial replacement for lost kidney function (renal replacement therapy) due to renal failure. Dialysis is the artificial process of eliminating waste (diffusion) and unwanted water (ultrafiltration) from the blood. In a healthy man, kidney does this process naturally. Some people may have damaged or failed kidneys which no longer filter toxins from the blood. They do purify their blood through dialysis. It is an artificial kidney used for excretion.It is used by those people whose kidneys were expired . UNDERSTAND |

Explain the principal and working of electri motor |
|
Answer» Working\tWhen the current begins to flow, current flows through brush X, then A to B, B to C, C to D and then to brush Y and into the battery.\tNow applying Fleming\'s Left Hand Rule to wire AB, Current is along AB, Magnetic Field is as shown (North-> South), the motion of the wire is downwards.\tNow applying Fleming\'s Left Hand Rule to wire CD, Current is along CD, Magnetic Field is as shown (North-> South), the motion of the wire is upwards.\tThe rectangular coil begins to move in the anti-clockwise direction\tNote that during anti-clockwise motion, the split rings and axle also move, whereas the brushes don\'t move.\tAfter half a rotation, Wire CD and Split ring Q moves to the left. Wire AB and Split ring P moves to right. Brushes X and Y donot move.\tNow applying Fleming\'s Left Hand Rule to wire CD, Current is along DC. (Battery -> Split ring Q -> DC , Magnetic Field is as shown (North-> South), the motion of the wire is downwards.\tNow applying Fleming\'s Left Hand Rule to wire AB, Current is along BA. (Battery -> Split ring Q -> DC --> CB -> BA --> Split ring P) , Magnetic Field is as shown (North-> South), the motion of the wire is upwards.\tSo, again the coil rotates in the anti-clockwise direction.\tThe reversal of current in the coil results in the continous rotation of the coil. The reversal of current is achieved by the commutator rings\t It works on principal of magnetic field |

Explain ohm\'s law in easy language |
|
Answer» Dear rajan kumar pasi please be in your limits here u r only for helping other students not to show your attitude to others or to say that i am intelligent . So if any student ask any question if u know answer ur work is only to typ answer not to show ur attitude Koi chewing to hai nhi jo bas one word mein samajh aajaye,. Statement hi easy hai tum dimmaag nhi laga paa rahe samajhne mein. Dear Muktid joshi yes V-IREasy language the principle that the electric current passing through a conductor is directly proportional to the potential difference across it, provided that the temperature remains constant. The constant of proportionality is the resistance of the conductorOHM’s law states that under no same temperature,\xa0electric current\xa0flowing through an ideal conductor is\xa0directly proportional to the potential difference\xa0across its ends.V ∝ IV = IR, R – Resistance\tResistance\xa0is a property of conductor to resist flow of charge through it. Its SI unit is\xa0Ohm (Ω).R = V/I, 1 Ohm = 1 Volt/ 1 Ampere\tI = V/R denotes that\xa0Current is inversely proportional to Resistance. Hence, greater the resistance lesser will be the flow of current and vice-versa.\tA\xa0rheostat\xa0or a\xa0variable resistor\xa0is a device or a component which allows changing of resistance in a circuit keeping the voltage same.\tIn a conductor, electrons are attracted by the atoms. This is a resistive force which is lower for a good conductor but very high for an insulator. A conductor having some resistance is called a\xa0Resistor. |

Function of fallopian tube |
|
Answer» It is the way from where sperms reach ovaries The Fallopian (or uterine) tubes are two tubes that extend from the uterus towards the ovaries.The Fallopian tube has three sections: the narrow isthmus that connects with the uterus, the broader ampulla in the middle, and the flared infundibulum with fimbriae that serve to direct the released ovum from the ovary towards the uterus.Generally, fertilisation of the ovum with sperm takes place within the ampulla, after which the fertilised ovum is conducted to the uterus for nidation (implantation). |

Discuss 3 types of heterotrophic nutrition with the help of examples |
|
Answer» In a holozoic mode of nutrition, the organism feeds on complex organic matter. They ingest the complex organic matter, digest and absorb the nutrients. Example: Dog, Human beings, etc. Examples of parasitic mode of nutrition are mosquito,ticks, lice, bedbugs , tapeworm . The mode of nutrition in which an organism obtains nutrients from dead and decaying organic matter is called saprophytic nutrition. Example - Rhizopus (bread mould), Mucor (pin mould), Yeast, Agaricus (mushroom) . Heterotrophic nutrition is of three types – saprophytic, parasitic and holozoic. |

what is achi genrator |
| Answer» AC generator, also known as alternators, is a machine that converts mechanical energy into electrical energy. The generated electrical energy is in the form of an alternating current sinusoidal output waveform. The mechanical energy is usually supplied by steam turbines, gas turbines and combustion engines.AC generators work on the principle of Faraday’s law of electromagnetic induction which states that electromotive force -EMF or voltage – is generated in a current carrying conductor that cuts a uniform magnetic field. This can either be achieved by rotating a conducting coil in a static magnetic field, or by rotating the magnetic field that contains the stationary conductor. The preferred arrangement is to keep the coil stationary because it is easier to draw induced alternating current from a stationary armature coil than a rotating coil.. | |

Why reproduction is important in organisms |
|
Answer» Reproduction is the process by which new individuals are produced by the parents. This process is very important in maintaining stability in the ecosystem and for the continuation of life on earth. Had there been no reproduction, all the species would have become extinct.Reproduction maintains a balance between the birth rate and death rate. The new individuals replace the old and the dying population. It also helps in increasing the number of species in the ecosystem.The genes are transmitted from the parents to the offspring. This leads to the evolution of species. Variations in species and their ability to survive in different environments is the result of reproduction. To produce more organisms of same genus. |
