Write three examples of redox reaction ..? |
|
Answer» H2S + Cl2\xa0→ 2HCl + SThe O.N. of S increases from -2 to 0. So it is undergoing oxidation and O.N. of Cl2\xa0decreases from 0 to -1. So it is undergoing reduction. Therefore it is a redox reaction.CuO + H2\xa0→ Cu +H2OIn this redox reaction, CuO is getting reduced to Cu since Oxygen is getting removed. So, the conversion of CuO to Cu is reduction reaction. H2\xa0is getting oxidised to H2O. So, it is oxidation reaction.Fe(s) + CuSO4(aq) → FeSO4(aq) + Cu(s)Oxidation state of Fe changes from 0 to +2 and oxidation state of Cu changes from +2 to 0. C+o2 give co2 |

Describe the mechanism of breathing in human. Being |
|
Answer» Breathing consist of inhalation and exhalation. Inhalation means taking air in, to get oxygen and exhalation means expelling air out to release carbon dioxide. A breathe means one inhalation and one exhalation. It involves the movement of ribcage and diaphragm. Diaphragm is made up of muscles which form the floor of chest cavity, where lungs are situated.Steps of breathing mechanism in humans:i) Inhalation:\xa0During inhalation rib cage moves up and out and, diaphragm contracts and move down. This leads to increase in space of chest cavity and decrease in pressure of lungs. Then air goes into lung to fill the space with air.ii) Exhalation: Exactly reverse of inhalation occurs in exhalation. Rib cage moves down and inwards, whereas diaphragm relaxes and moves up. This reduces the size of chest cavity and increase in pressure, so air is pushed out of the lungs. When we inhale air,it passes through our nostrils into the nasal cavity. from the nasal cavity,the air reaches our lungs through the wind pipe.lungs are present in the chest cavity.this cavity is sorrounded by ribs.a large muscular sheet called diaphram forms the floor of the chest cavity.breathing involves the movement of the diaphram and the rib cage.during inhalation,ribs moves up and outwards and diaphram moves down.this movement increases space in our chest cavity and air rushes into the lungs.the lungs get filled with air.during exhalation,ribs move down and inwards while diaphram moves up to its former position.this redues the size of the chest cavity and air is pushed out of the lungs. |

Why the right kidney is placed lower comparatively then left kidney? |
|
Answer» Thankyou so much yogita In humans, the kidneys are located in the\xa0abdominal cavity. The right kidney is placed at a slightly lower level than the left kidney in order to accommodate the largest gland/organ of the body, the liver. The liver bulges out on the right side of the body and then, tapers off to the left. Since, the abdominal cavity is limited in space, the body has been designed by nature to accommodate a large part of the liver by placing the right kidney at a slightly lower level as compared to the left kidney.\xa0 Because heart exisist in lower side of left kidney |

Describe the role of micelles in cleaning? |
|
Answer» Ryt In water, the soap molecule is uniquely oriented which helps to keep the hydrocarbon part outside the water. When the clusters of molecules are formed then hydrophobic tail comes at the interior of the cluster and the ionic end comes at the surface of the cluster and this formation is called micelle. When the soap is in the form of micelles then it has the ability to clean the oily dirt which gets accumulated at the center. These micelles remain as a colloidal solutions. Therefore the dirt from the cloth is easily washed away. The soap solution appears cloudy as it forms a colloidal solution which scatters light. |

Define structure and function of nephron |
|
Answer» The excretory units of the kidneys are called nephrons. Each kidney has a large number of nephrons packed close together.Each nephron has a cup-shaped start called the \'Bowman\'s capsule\' into which project a tuff of capillaries called \'Glomerulus\'. The blood is brought into the kidney by the glomerulus. After the filtration in the Bowman\'s capsule, blood enters into the tubular part of the nephron where useful molecules like glucose, amino acids, salts, vitamins and a major amount of water\xa0etc. are selectively reabsorbed as urine flows along the tube. The final filtrate is finally drained into the ureters. The final waste contains water and nitrogenous wastes like urea, uric acid, etc.Functioning of Nephron\tFiltration: Filtration of blood takes place in Bowman’s capsule from the capillaries of glomerulus. The filtrate passes into the tubular part of the nephron. This filtrate contains glucose, amino acids, urea, uric acid, salts and a major amount of water.\tRe-absorption: As the filtrate flows along the tubule useful substances such as glucose, amino acids, salts and water are selectively re-absorbed into the blood by capillaries surrounding the nephron tubule.\tUrine: The filtrate which remains after re-absorption is called urine. Urine contains dissolved nitrogenous waste, i.e. urea and uric acid, excess salts and water. Urine is collected from nephrons by the collecting duct to carry it to the ureter. thanks |

Explain the digestive system in human being |
| Answer» When we ingest food in our mouth, salivary glands of the mouth secrete saliva which moistens the food. It also converts the starch Into sugar. The tongue helps in chewing by moving the food in various directions. Saliva contains enzyme called salivary amylase which converts starch into sugar.Oesophagus Eh From mouth food goes into foodpipe called oesophagus. As food enters into the foodpipe, muscles of its wall start contraction and relexation movement. This movement is called peristaltic movement that pushes the food into the stomach. The peristaltic movement occurs throughout the alimentary canal. The oesophagus leads the food a sac like structure called stomach. The food is churned and partly digested in the stomach. The semi-solid food passes from the stomach to much coiled tube-like structure called the small intestine. The small intestine. serves two purposes—digestion and absorption of the digested food. It is about 20 feet long. The inner surface of the small intestine has a large number of fingerlike projections called villi. The Villi increase the surface area for the absorption of digested food. The absorbed food enters into the blood stream and carried away to various parts of the body for assimilation. The undigested food moves from the small intestine to the large intestine where mainly absorption of water from the undigested food takes place. From the large intestine the undigested food passes to the rectum which pushes it out of the body through the opening called the **** as faeces. | |

|
| 54550. |
Does board paper come from ncert always?? Like If I just do ncert can I score 95+ |
|
Answer» NCERT is absolutely enough for subjects like Chemistry , Physics , English , Social Sciences but I may not say the same for Mathematics . RD Sharma or RS Aggrawal is generally considered the most important supplementary material for Maths along with thorough practice of NCERT as well. For some subjects ncert is sufficient but not for maths and science little bit towards sst also Ncert is sufficient yes Ncert is more than enough..bt for subjects like hindi and english...bt to some extent it is benefial for sst also..bt you need to practice some extra questions fr sst..bt yes for maths- ncert is enough..bt you should be aware that maths need a lot of practice....so you should practice rd sharma..aur any other good reference book like xam idea also...bt there are some conepts in rd sharma which are not at 10th level..so no need to do that...and yes for science especially for physics you need to go through some extra books like all in one , xam idea is best....bt after completing yur ncert...give yur first priority to ncert..!! Hope your doubt is cleared now...and all the best??? Actually the board paper is all "based" on the topics of ncert... But it never means that only ncert can give you 95+.... In subjects like s.s.t. , hindi and english ncert is more than enough.... But the problem begins in the case of science and mathematics.... In science there are 90% topics in which only ncert is enough but for the other 10% you definitely need other books...chs like carbon and its compounds, magnetic effects..etc... Need books other than ncert... Bcoz in this case ncert is neither sufficient not absolutely reliable....and in mathematics you just need to clear your basics for which ncert is enough but maths demands practice and so uou have to move towards books like R.D. Sharma and so and so....hope it helps...? |
