How blood clots |
| Answer» Blood clotting is the mechanism by which blood oozing out from the injury stop suddenly to prevent the loss.Platelets are the non nucleated blood cells which bring about clotting of the blood. Platelets are special irregular cells present in the blood. These are also called as thrombocytes as they lyse and release thromboplastin which brings about clotting of blood. Presence of calcium is also necessary for blood clotting. Platelets also aggregate in large amounts to form a plug at the injury preventing the blood loss. Blood clotting is very essential for an individual to prevent the loss of blood and later anaemia. | |

Reason for exsistensive of decompositio |
| Answer» The importance for the existence of decomposers in an ecosystem are as follows:1) decomposers clear the ground of all the dead bodies of plants and animals by decomposing them.2) they helped to maintain the chain of carbon cycle by decomposing the bodies of Dead plants and animals.\xa0ORDecomposers are the microorganisms such as bacteria and fungi that consume dead organic material. Decomposers play an important role in the environment.1. These organisms process organic constituents (e.g., plant material) to release carbon and other nutrients such as nitrogen (N) and phosphorus (P). This process helps in transfer of energy and cycling of nutrients between various trophic levels in an ecosystem.2. These help in the formation of soil. These add organic matter by degrading energy rich organic compounds and producing more refractory materials such as humus.3. They help in decomposing of the dead bodies of plants and animals, and hence act as cleansing agents of environment. | |

versatile nature of carbon? |
| Answer» The word verstaile means having great diversity or variety.Carbon is a very friendly element. The number of carbon compounds which are known to scientists till date is more than three million. It is owing to this property of it is called a versatile element.This versatile nature is because of:Tetravalency:Tetra means four and valency means the number of electrons gained or losed or shared to attain stable configuration. So, tetravalency refers to the phenomenon of sharing four electrons by an element to attain stable condition.Now, the electronic configuration of carbon is 2, 4. It shares four electrons with other elements to attain a stable configuration.Catenation:This is a property of self-linking. This property depends on size of atom which will decide the M-M bond strength. This property is more unique for carbon as more than thousand atoms of carbon can be linked together. | |

How do nervous tissue cause action? |
| Answer» \tNervous tissue is the main component of the nervous system,\xa0which regulates and controls body functions.\xa0It is specialised to react to stimuli and to conduct impulses to various organs in the body which bring about a response to the stimulus.\tNervous tissue\xa0is composed of neurons, which transmit impulses, and the neuroglia, which assist propagation of the nerve impulse as well as provide nutrients to the neuron. Neurons are easily stimulated and transmit impulses very rapidly.\tNerve cells communicate with each other at a junction known as a synapse, where the terminal branches of an axon and the dendrites of another neuron lie in close proximity to each other but normally without direct contact. Information is transmitted across the gap by chemical secretions called neurotransmitters. It causes activation in the post-synaptic cell. Thus impulses pass from one neuron to the next.\tNervous tissue allows an organism to sense stimuli in both the internal and external environment.\tThe stimuli are analysed and integrated to provide appropriate, co-ordinated responses in various organs.\tThe afferent or sensory neurons conduct nerve impulses from the sense organs and receptors to the central nervous system.\tConnector neurons supply the connection between the afferent and efferent neurons as well as different parts of the central nervous system.\tEfferent or somatic motor neurons transmit the impulse from the central nervous system to a muscle (the effector organ) which then react to the initial stimulus.\tAutonomic motor or efferent neurons transmit impulses to the involuntary muscles and glands. | |

With the help of an example explain the process of hydrogenation |
|
Answer» Hydrogenation is the process of addition of hydrogen to an unsaturated organic compound (compounds containing double or triple bond) to convert it into a saturated compound (compound containing single bonds). This process requires catalyst, non-catalyzed hydrogenation occurs only at very high temperatures.For example, let us consider the hydrogenation of ethene (CH2)=CH2. The process of adding a hydrogen in hydrocarbon is called hydrogenation |

Give differences between bar magnet and solenoid |
| Answer» 1) The poles of the bar magnet do not lie exactly on the end of the magnet but is somewhat inside. In solenoid poles can be considered to be lying at the edge.2) The magnetism retains in the bar magnet naturally but in solenoid the magnetism is there so long current flows through it.3) Magnetic field of a bar magnet emanates from throughout the body of the magnet, with more intensity at the poles. While there is no field emanating from the lateral surface of the solenoid.4) Magnetic poles of a bar magnet lies a little inside the geometrical end of the pole while magnetic pole of a solenoid exists just at the geometrical end of the solenoid.5) When electric current is passed through a current carrying solenoid, a magnetic field is observed a round the solenoid, ie the solenoid behaves like a magnet as long as current passes through the solenoid.Pattern of field lines indicate that solenoid behaves like a bar magnet. | |

Describe dc generator |
| Answer» \tIf two half slip rings are connected to ends of the coil the AC generator works as DC generator to produce DC current.\tWhen the coil is in the vertical position the induced current generated during the first half rotation rises from zero to maxi¬mum and then falls to zero again.\tAs the coil moves further from this position, the ends of the coil go to other slip rings.\tHence during the second half rotation the current is reversed in the coil itself, the current generated in the second half rotation of the coil is identical with that during the first half of direct current.\t | |

| 55084. |
Why do carbon formes covalent compound |
|
Answer» Carbon forms covalent bonds to complete its outermost shell and achieve the noble gas configuration. Also carbon cannot take electrons because then there will be so many no. Of electrons and nucleus cannot hold them . It can also not donate electrons as it requires a large amount of energy Covalent bond is a bound which is formed by the sharing of electrons in the outermost shell of carbon atom, there are four electrons left which are called valence electrons.valence electrons determine the valency of an atom. it requires large amount of energy to lose or gain four electrons..i.e carbon is tetravalent so carbon prefers to share electrons rather than to lose or gain.. u can say that it is friendly in nature..since it shares electrons..since it shares electrons it forms covalent bonds. other reason behind dis is that it has catenation property..i.e it has property of forming long chains..carbon chain can be made up of 60 carbon atoms together. |

Where is the grinding of food done in grasshoppers? |
| Answer» The alimentary canal of grasshopper is equipped with a structure called Gizzard. The food (mainly leaves) gets churned in Gizzard first before it goes further for digestion and assimilation.Digestion starts at the mouth with the mandibles and the maxillae chewing the food. It is also acted upon by enzymes of salivary juice, the salivary carbohydrases which partially digest the food. The food is then swallowed with the help of lubrication provided by the salivary juice.The food then enters the oesophagus and then into the crop. Here, the masticated food is temporarily stored.The food then passes into the gizzard which acts as the grinding chamber. At the junction of the gizzard and the stomach is a valve called the pyloric valve. It allows the passage of only the thoroughly digested food into the stomach and also, prevents the regurgitation of food from the stomach. | |

Who was BR ambedkar and what was role in poona pacts |
|
Answer» Thanks seth g Dr. Bhim Rao Ambedkar was nominated as a delegate of the oppressed classes for the Second Round Table Conference. In that Round Table Conference, he clashed with Mahatma Gandhi by demanding separate electorates for the Dalits.\xa0When the British Government accepted the Ambedkar\'s demand, Gandhiji began a fast unto death. He believed that separate electorates for the Dalits would slow down the process of their integration into the society. This issues was eventually resolved through the Poona Pact of September 1932.It gave the Depressed classes (which later came to be known as The Scheduled Castes) reserved seats in the provincial and central legislative councils, but they were to be voted in by the general elections. |
