Explain the human digestivee systemdetails |
|
Answer» Entire information about digestive system is given. You can mould it as per your requirement.Digestion: Digestion is the process by which food is broken down into simple absorbable substances. Digestion of food takes place in the digestive system. Digestive system is made up of alimentary canal and associated glands. Parts of alimentary canal:The mouth, oesophagus, stomach, small intestine and large intestine form the alimentary canal. It is also known as the digestive tract.Mouth is guarded by upper lip and lower lip. The process of taking in food through mouth is called as ingestion.Buccal cavity is the inner region of the mouth. It encloses teeth and tongue.Teeth are of different types namely, incisors, canines, premolars and molars.Incisors are used for biting food.Canines are sharp and pointed and are used to pierce or tear food.Premolars and molars are the principal grinders helping to chew and grind the food.Tongue is a muscular organ attached to the floor of the buccal cavity at the back. It helps in mixing of food with saliva and swallowing it. It also helps in tasting different types of food with the help of taste buds present on it. The buccal cavity leads into pharynx.Pharynx is at the back of buccal cavity. The pharynx is the common channel for food and air. When you swallow food, a flap-like valve called the epiglottis closes the windpipe. It prevents the entry of food particles into respiratory tract.Oesophagus also called as food pipe helps in conveying the food from buccal cavity to stomach. The oesophagus is also known as the gullet. It is about 25 centimetres long. Food inside the oesophagus reaches the stomach by peristalsis movements.Stomach is the widest part of the alimentary canal. It is a J-shaped muscular organ with stomach occurs with the help of digestive juice. Digestive juice comprises of hydrochloric acid, mucous and some enzymes.Small intestine is made up of three regions namely duodenum, jejunum and ileum. Partially digested food called the chyme from the stomach is received by the duodenum. Duodenum also receives bile form the liver, enzymes from pancreas and secretes some enzymes on its own. All these substances bring about digestion of food in the intestine. The inner walls of the small intestine have millions of small finger like projections called the villi. Villi increase the surface area for digestion as well as absorption of digested food by eight times.Large intestine comprises of colon and rectum. Undigested food is sent into large intestine. Water from the food is reabsorbed to a great extent in the large intestine. Undigested waste is stored in the rectum for defecation.**** is the opening of the alimentary canal to the exterior. This helps in the elimination of faeces by the process of egestion.Associated glands: These glands include salivary glands, gastric glands, intestinal glands, liver and pancreas.Salivary glands are present inside the buccal cavity. They secrete saliva. This saliva plays an important role in breaking down complex components like starch into simple sugars.Gastric glands present inside the stomach secrete gastric juice which helps in the digestion of food.Intestinal glands secrete various enzymes which aid in the process of digestion of food.Liver is the largest gland in our body. The liver secretes a yellowish green watery fluid called bile. It is temporarily stored in a sac called the gall bladder. Bile plays an important role in the digestion of fats. Bile is sent into duodenum through a narrow tube-like structure called the bile duct. Bile breaks the larger fat molecules into tiny droplets, thereby increasing their surface area, which helps in the digestion of fats easily.Pancreas is the mixed gland. It acts as a both endocrine and exocrine gland. The pancreas secretes the pancreatic juice that helps to digest carbohydrates, proteins and fats. The pancreatic juice converts carbohydrates into simple sugars and glucose, proteins into amino acids, and the lipids into fatty acids and glycerol. Science ka paper Ho gya |

Explain the process of extraction of mercury from its ore |
|
Answer» The process of extraction of Mercury metal from its ore Cinnabar (HgS). Most of the world\'s mercury is obtained from its main ore, cinnabar or vermillion with the chemical structure mercury sulphide (HgS). Cinnabar is usually found in a massive or granular form but can also occur as small crystals Yar!Science exam is finish. Not take tension Ore of Mercury is cinnabar.. Mercury oxide is obtained from its cinnabar ore by the process of roasting.. Then the oxide of Mercury is heated to get the Mercury.... The ore of mercury is called as cinnabar. |

Why do plants take in oxygen and release out carbon dioxide at night?? |
|
Answer» Photosynthesis and respiration are two different processes.Photosynthesis takes place in the light which is available only during the daytime. In this process, plants take in carbon dioxide\xa0and give out oxygen. However, at night, in the absence of sunlight, photosynthesis does not occur. Hence,\xa0there is no release of oxygen during the night.Respiration is a continuous process which takes place during the day and also at night. In this process, plants take in oxygen and give out carbon dioxide. Hence, there is a\xa0continuous release of carbon dioxide during the daytime and nighttime. However, during the daytime, the waste carbon dioxide released during respiration is utilized by the plants for photosynthesis.As a result, it appears as if plants give out oxygen only during the day and carbon dioxide during night. However, respiration occurs continuously day in and day out. Refer below one |

Why plants take in oxygen and release co2 at night. |
| Answer» Plants need oxygen to live and they take oxygen ay night . The reason that they take co 2 at day time for the sake of photosynthesis as light is present at day time. So to prepare food the raw materials are water and carbondioxide so they take in co2 for sake of photosynthesis and release 02 as byproduct. At night they take in o2 to carry on living☺ | |

State ohm\'s law state its limitation? |
|
Answer» Ohm\'s law states that at a constant temperature, current \'I\' through a conductor between two points is directly proportional to the potential difference or voltage \'V\', across the two points. That is, Thus, the ratio V : I is a constant. This constant is called as the resistance (R) of the conductor V=IR: R=V/I IR=V ohms law is not applicable in unilateral network also it is not applicable for non linear network |

Difference between between corrosion and rancidity |
| Answer» Corrosion:\xa0It is the process in which metals are slowly eaten up by the action of air moisture or chemicals. For example rusting is a form of corrosion in which iron is eaten up by the action of air and moisture and a reddish brown coating of iron oxide is formed as shown in the following chemical reaction.Rancidity:\xa0When the substance containing oils and fats are exposed to air they get oxidised and become rancid due to which their smell, taste and colour change. This process is known as rancidity. For example when a when butter is kept open for a long time then its smell and taste gets changed. | |
