How does digestion takes place in amoeba |
|
Answer» Amoeba is a holozoic and protozoan. The digestion is intracellular as it is a unicellular organism. The food taken remains in a food vacuole or gastric vacuole formed by the cell membrane and a bit of the cytoplasm. The vacuoles are transported deeper into the cells by cytoplasmic movements. Here they fuse with lysosomes that contain enzymes such as amylase and proteinase. Thus, amoeba can digest sugar, cellulose and protein. Fats, however, remain undigested.Nutrition in Amoeba:-Food - Amoeba is a holozoic and omnivorous animal. It feeds upon microscopic organisms like bacteria, Paramecium, Diatoms, Algae and dead organic matter.Nutrition in Amoeba involves the following steps:(i) Ingestion:- Amoeba has no mouth so ingestion may occur at any point of body surface but generally it occurs at the advancing end of the body. Ingestion occurs with the help of pseudopodia. The opening of food cup gradually becomes narrower and narrower, and finally closes. So the food is finally enveloped and taken inside a food-vacuole (called phagosome) along with a drop of water.(ii) Digestion:- Amoeba shows intracellular and vacuolar digestion. In the cytoplasm, food vacuole fuses with lysosomes containing digestive enzymes. In this, the complex and non-diffusible nutrients are changed into simple and diffusible nutrients. Medium inside the food vacuole is first acidic but later becomes alkaline, (as in the alimentary canal of man).(iii) Absorption:_ In absorption, the diffusible nutrients pass through the vacuolar membrane into the cytoplasm by diffusion and are then distributed to all the body parts by streaming movements of cytoplasm called cyclosis. Due to this, the size of food vacuole gradually decreases.(iv)Assimilation: In the cytoplasm, a part of the absorbed food is oxidised to produce energy, most of the simple nutrients are combined to synthesise complex compounds. Thus, the absorbed food materials are utilised to get energy through respiration and make the different parts of Amoeba cell and it leads to the growth of Amoeba.(v) Egestion: Egestion may occur at any point on the body surface. They have enzymes in the food vacoule Digestion in amoeba takes place by finger like extension called psuedopodia |

Explain how does current flow in a conductor ? |
| Answer» Bodies in which the application of an electric field results in the generation of an electric current due to the movement of the electrons is called an Electrical Conductor. In such bodies, the electrons are free to move around inside the body and their random motion can be influenced by an electric field. Most electrical conductors are metals mainly because metals possess electrons in the outermost orbit where they are most loosely held and can move around easily. The wires supplying electricity to your houses are supplying fresh energetic electrons to your house for you to use. We have learn’t to use it and we have become completely dependent on electricity. | |

What is van der waal\'s force? |
|
Answer» A weak force of attraction between electrically neutral molecules that collide with or pass very close to each other. The van der Waals force is caused by the attraction between electron-rich regions of one molecule and electron-poor regions of another (the attraction between the molecules seen as electric dipoles). The attraction is much weaker than a chemical bond. Van der Waals forces are the intermolecular forces that cause molecules to cohere in liquid and solid states of matter, and are responsible for surface tension and capillary action. It is a very weak force..... |

Elaborate the Digestion process? |
|
Answer» Refer any reference book A human digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the entire body. The food we take in is digested and utilized by our body and the unused parts of the food are defecated. Human digestive system is the sum of the gastrointestinal tract (GIT; also called alimentary canal) and accessory organs (tongue, liver, pancreas, etc). These two parts together help in digestion in humans.The alimentary canal is the long tube through which the food that we eat is passed. It begins at the mouth (buccal or oral cavity), passes through the pharynx, esophagus or food pipe, stomach, small intestines, large intestines, rectum and finally ends at the ****. The food particles get digested gradually as they travel through various compartments of the alimentary canal. Accessory organs are organs which participate in the digestion process but are not actually a part of GIT. They stimulate the digestion by releasing certain enzymes.Food begins its journey through the digestive system in the mouth, also known as the buccal cavity or the oral cavity. The mouth has many accessory organs such as the tongue, teeth, and salivary glands, which help in the digestion of food. Teeth grind the food into small pieces. Salivary glands secrete saliva which contains an enzyme called the salivary amylase. This enzyme breaks down starch content and moistens the food, before the tongue and other muscles push the food into the pharynx.\xa0Pharynx: The pharynx passes the chewed food from the mouth to the esophagus. The flap of tissue known as the epiglottis present in pharynx prevents food from entering into the wide pipeEsophagus or Food PipeThe esophagus is a muscular tube connecting the pharynx to the stomach. It carries swallowed masses of chewed food along its length and pushes it down to the stomach.\xa0Stomach: The stomach is a thick-walled muscular bag that is located on the left side of the abdominal cavity. It is the largest part of the human digestive system. Stomach acts as a storage tank for food so that the body has time to digest large meals properly. It receives food from the food pipe at one end and opens into the small intestine at the other end. The inner walls of the stomach consist of the gastric glands which secrete mucous, hydrochloric acid and digestive enzymes. These continue the digestion of food that began in the mouth.Mucous protects the lining of the stomach while acid kills bacteria that enter the body along with the food. Hydrochloric acid also makes the medium in the stomach acidic, which helps the digestive enzymes like pepsin to act. The digestive enzymes break down proteins into simpler substances.Small Intestine: The small intestine is the longest part of the human digestive system. It is a highly coiled long, thin tube which is about 7.5 metres in length. The length of the small intestine depends on the diet of the organism. A major proportion of digestion takes place in the small intestines. All types of nutrients are digested here with the help of secretions which it receives from the liver and the pancreas. The walls of the small intestine also secrete juices for digesting food.The liver releases bile juice which alkalizes the acidic food received from the stomach and also emulsifies the fat content. The pancreatic juice digests the proteins and lipids. Finally, the intestinal secretions convert the carbohydrates into glucose, proteins to amino acids and fats into fatty acids and glycerol.Once the food is broken down into the simple particles, it is ready to be absorbed by the body. The villi, finger-like projections present on the walls of the small intestine, absorb the digested food by increasing the surface area. The absorbed food is then transported to different parts of the body through the blood vessels for cell activities.Large Intestine: The large intestine is a long, thick tube which is about 1.5 meters long. The large intestine absorbs water and small amounts of nutrients from the undigested food with the help of many symbiotic bacteria residing in it. The remaining waste passes into the rectum, where it remains as semi-solid feces. Feces exit the body through the **** via time-to-time excretion. This process is called Digestion. |

Explain the process of digestion?class 10 |
|
Answer» The major organs or structures that coordinate digestion within the human body include the mouth, esophagus, stomach, small and large intestine, and liver.Mouth-\xa0The mouth\xa0is a specialized organ for receiving food and breaking up large organic masses. In the mouth, food is changed mechanically by biting and chewing.\xa0Food is moistened by saliva.\xa0The saliva contains an enzyme called amylase, which digests starch\xa0into\xa0maltose. During chewing, the tongue moves food about and manipulates it into a mass called a bolus. The bolus is pushed back into the pharynx\xa0and is forced through the opening to the esophagus.Esophagus-\xa0The bolus of food moves through the esophagus by peristalsisStomach - The stomach is an expandable pouch located high in the abdominal cavity. Layers of stomach muscle contract and churn the bolus of food with gastric juices to form a soupy liquid called chyme. The stomach stores food and prepares it for further digestion. In addition, the stomach plays a role in protein digestion. Gastric glands called chief cells secrete pepsinogen, which is converted to\xa0pepsin in the presence of hydrochloric acid.\xa0The pepsin then digests large proteins into smaller proteins called peptides. To protect the stomach lining from the acid stomach\xa0cells secretes mucus that lines the stomach cavity.Small intestine: The\xa0chyme enters from\xa0stomach to the small intestine. The three parts of small intestine are\xa0duodenum, jejunum and\xa0ileum. The inner surface of the small intestine contains numerous fingerlike projections called villi. Each villus has projections of cells called microvilli to increase the surface area.Most chemical digestion takes place in the duodenum. In this region, enzymes digest nutrients into simpler forms that can be absorbed. Intestinal enzymes are supplemented by enzymes from the pancreas. In addition, bile enters the small intestine from the gall bladder to assist in fat digestion.The enzymes functioning in carbohydrate digestion include amylase (for starch), maltase (for maltose), sucrase (for sucrose) and lactase (for lactose).For fats, the principal enzyme is lipase. Before this enzyme can act, the large globules of fat must be broken into smaller droplets by bile.Protein digestion is accomplished by several enzymes, including two pancreatic enzymes: trypsin and chymotrypsin. Peptides are broken into smaller peptides, and peptidases reduce the enzymes to amino acids.Nucleases digest nucleic acids into nucleotides in the small intestine also.The products of digestion enter cells of the villi, move across the cells, and enter blood vessels called capillaries. Diffusion accounts for the movement of many nutrients, but active transport is responsible for the movement of glucose and amino acids. The products of fat digestion pass as small droplets of fat into lacteals, which are branches of the lymphatic system.Substances that have not been digested or absorbed then pass into the large intestine.Large intestine -\xa0The large intestine\'s chief functions are to absorb water and to store, process, and eliminate the residue following digestion and absorption. The intestinal matter remaining after water has been reclaimed is known as feces.\xa0The feces are stored in the rectum and passed out through the **** to complete the digestion process.
