How digestion occurs inside the body of human? |
|
Answer» Digestion Process :As we eat food, the food enters and travels through a long tube so-called gastrointestinal tract or the alimentary canal.The process of digestion has six steps, which are as follows:\tIngestion – the process of taking food in.\tSecretion – the salivary glands, inner walls of the stomach, small intestine, liver, and pancreas functions by secreting juices to aid the process of digestion.\tMixing and movement – the process of swallowing, moving the food through the food pipe and segmenting it in the small intestine.\tDigestion – the process of converting complex food particles into simpler substances in the presence of enzymes and acids secreted by different digestive organs.\tAbsorption – this begins in the stomach after the food has been broken down into simple molecules.\tExcretion – the process of removing indigestible substances from the body by the process of defecation so that there is no accumulate inside the gut. Digestion started with mouth.cuting of food is physical digestion. Saliva help ni first chemical digestion. Then food run to oesophagus,food pipe because now it sillpery by saliva.after it food runs to stomach there partical of food disgst.then small intestine mai fir large intestine mai fir as extra aap n ncert mai v dekh skte ho. |

Will the natural replenishment of soil take place even if decomposers are not there |
| Answer» Yes it can happen by the Physical and Industrial method.In physical method, when lightening strikes, the nitrogen is the atmosphere is converted to plant usable form due to high pressure and heat. But this phenomenon is rare, thus one cant depend on it.In Industrial method, Fertilizers are created by chemical process, and are effective, but when used in a long run, they change the composition of soil and degrade it. | |

What is do u mean by optically denser medium |
|
Answer» Such a medium in which there is very less space between the particles or comparatively high forces of attraction which restricts the beam of light The ability to refract light is represented by the optical density of a medium. A medium having larger refractive index is called optically denser medium, the optical density increases, and the speed of light in that material decreases. |

How do fungi take in fungi and nutrition |
| Answer» Fungi lack chlorophyll, fungi are unable to manufacture food out of the raw materials around them as plants do. Thus fungi are categorized as heterotrophic they must get nutrition from other organisms. Some fungal species get their food from living organisms, a process that may harm the host or benefit it. The vast majority of fungi obtain their nutrients from dead plant or animal matter. | |

What is volt ? |
|
Answer» Volt is comercial unit of potential differences 1volt = 1n of energy recquired to move 1 q of charge The volt (symbolized V) is the Standard International (SI) unit of electric potential or electromotive force. A potential of one volt appears across a resistance of one ohm when a current of one ampere flows through that resistance.The volt (symbol: V) is the derived unit for electric potential, electric potential difference (voltage), and electromotive force. It is named after the Italian physicist Alessandro Volta. |

pH of mouth is..?? |
|
Answer» The pH scale goes from 1 to 14, with a pH of 1 being the most acidic, and 14 being the most alkaline. A pH of 7 is neutral – the pH of pure water is very close to 7. At a pH of 5.5 the teeth begin to demineralize, putting them at risk for cavities. A healthy mouth is in a neutral pH range. About 6.2 The pH of fluids circulating around the human body (including the saliva in your mouth) register in a narrow pH range. The pH of blood should be approximately pH 7.3 (slightly alkaline) while healthy saliva should register |
