What is the difference between AC generator and DC generator? |
| Answer» The only difference between a DC generator and an AC generator is in the way the two ends of the generator coil are linked to the outer circuit.In DC generator we connect the two ends of the coil to the commutator consisting of two half rings of copper. On the other hand, in an AC generator, we connect the two ends of the coil to two full rings of copper called slip rings. There is no commutator in an AC generator. | |

Why DNA copying is essential part of the process of reproduction ? |
| Answer» DNAs are the carriers of genetic information. For an organism to produce its own kind, it becomes necessary that the offspring get similar DNAs as in parents. DNA replication is the way through which a cell makes additional copies of DNA so that they can be transferred to the offspring. This explains how DNA copying is an essential part of the process of replication. | |

write the chemical equation for anaerobic respiration in muscles? |
| Answer» Anaerobic respiration are produces energy and uses glucose, but it produces less energy then aerobic respration and does not require oxygen. Anaerobic respiration\xa0takes place in the cell cytoplasm and produces lactic acid. The chemical equation is C6H12O6 → 2C3H6O3 (Glucose → Lactic acid). The lactic acid then needs to be oxidised later to carbon dioxide and water afterwards\xa0to prevent it building up. This process requires oxygen and therefore following anaerobic respiration there is oxygen debt in the cell, as oxygen is needed to break down the lactic acid produced.\xa0 | |

What are the functions of four-chambered heart? |
|
Answer» R u not studying ingle or whatever O hello it is double circulation The function of human heart :-* It is a four chambered structure consisting - the right auricle , the left auricle , right ventricle and left ventricle.* The Auricles are smaller and placed above the ventricles. Auricles are partitioned by a muscular called septum.* The right auricle receives the deoxygenated blood from all parts of the body except the lungs. It pumps this blood into the right ventricle. Then , the right ventricle pumps the deoxygenated blood to the lungs. The left auricle receives oxygenated blood from the lungs through pulmonary veins. It pumps this blood into the left ventricle. The left ventricle pumps the oxygenated blood to the distant organs in the body.* Each auricle communicates with the ventricle of its side by a pore which is guarded by valves. These valves allow the blood to flow from the auricles to the ventricles but check its return to the auricles. Thus , the heart there is a complete separation of oxygenated and deoxygenated blood. The heart is enclosed in a double membrane called pericardium. It contains fluid which protects the heart from any shock or mechanical injury.*The heart collects blood through both the auricles and then distributes it through ventricles. The action of heart includes contraction and relaxation of the auricles and ventricles.* A contraction of heart is called systole and diastole. The contraction and relaxation occur in an automatic rhythmic fashion. The auricles and ventricles contract alternately. The rhythmic contraction and relaxation of heart is called a heart beat. There is regulation of blood two times in the body and oxygenated and deoxygenated blood are kept separated |

Newton 1st law of motion with proof |
| Answer» Sir Isaac Newton published three laws in 17th century. In this article, we are going to talk about Newton’s first law. This law laid emphasis on the motion of the object and the force acting on it. In other words, it deals with the motion of an object and its relation to force.“A body remains in the state of rest or uniform motion in a straight line unless and until an external force acts on it.” | |

newton1st law with proof |
|
Answer» Newtons first law states that: A OBJECT AT REST REMAINS IN REST AND A OBJECT IN MOTION REMAINS IN MOTION UNTILL AND UNLESS AN EXTERNAL UNBALANCED FORCE IS APPLIED TO IT.This is also referred to as the law of inertia.When a person is inside the moving bus he is stationary but the bus is moving and if the driver applies brakes then a peson tends to lean or go firward this is because pf the NEWTONS FIRST LAW.thankyou.Regards,Anmol Every action have equal and opposite reaction |
