Points adout human digestive system |
| 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. | |
| 60304. |
How small intestine helps in digestion |
| Answer» After being in the stomach, food enters the duodenum, the first part of the small intestine. It then enters the jejunum and then the ileum (the final part of the small intestine). In the small intestine, bile (produced in the liver and stored in the gall bladder), pancreatic enzymes, and other digestive enzymes produced by the inner wall of the small intestine help in the breakdown of food. The digestion of food gets completed in small intestine. After passing through the small intestine, the undigested food passes into the large intestine for absorption. | |

Why is insufficient to meet oxygen requirement of multicellular organism like human? |
|
Answer» In multicellular organisms such as man, the volume of the human body is big and hence, oxygen cannot diffuse into all the cells of the human body quickly. Diffusion, being a slow process will take a lot of time to circulate oxygen to all the body cells. Hence, diffusion is insufficient to meet the oxygen requirements of multicellular organisms like humans. Bcoz simple diffusion is not sufficent to meet the oxygen requirement and all cells in multicellular organisms are not in direct contact with the surrounding environment.... U missed diffusion bro |

How nerves cell works |
|
Answer» I hope u clear this answer!! ? The nervous system is a complex action of nerves and specialised cells known as neurons that transmit signals b/w different parts of the body. The somatic system consist of nerves that connect the brain and spinal cord with muscles and sensory receptors in the skin The \'control centre\' of the cell is known as cell body. The axon transmits electric impulse from the cell body. The dendrites are branching fibres that receives electric signals from other neuron. The shape of the body is determined by the job it does.

I need best notes of asexual reproduction |
| Answer» When a single parent is involved and no gamete formation takes place; the method is called asexual reproduction. No meiosis happens during asexual reproduction.It takes place by 6 methods.\tFission: In the process of fission a unicellular organism split to form two or more new organism.\tBudding: In budding a small part of a body of parent organism grows out as a bud which then detaches and become a new organism. For Example: Hydra, yeast reproduce by budding.\tSpore formation: In spare formation, the parent plant produces 100 of microscopic reproductive units called “spores” with in the spore case. When the spore case burst, then the spores spread into air. When these air borne spores land on food or soil, under favorable condition they germinate and produce new plants for example: Most of the fungi such as Rhizopus ( bread mould) ,mucor, bacteria, non-flowering plants, ferns and mosses.\tRegeneration: The process of getting back off full organism from its body part is called regeneration. For example simple animals like Hydra and Planaria show regeneration.\tPlanaria (Flatworm) is found in freshwater ponds. If the body of planaria somehow gets cut into number of pieces then each body piece can regenerate into complete planaria.\tFragmentation: The breaking up of body of simple multicellular organism into two or more fragments or maturing, each of which subsequently grows to form a new complete organism is known as fragmentation. Spirogyra is a green filamentous algae. Spirogyra breaks into two or more fragments on maturing and each fragments then grows into new spirogyra.\tVegetative Propagation: In vegetative propagation new plants are obtain from the parts of old plants (stem, leaves, or root) without the help of any reproductive organ. | |

How do Mendel\'s experiment show that traits may be dominant or recessive ? |
| Answer» Mendel selected true breeding tall (TT) and dwarf (tt) pea plants. Then, he crossed these two plants. The seeds formed after fertilization were grown and these plants that were formed represent the first filial or F1 generation. All the F1 plants obtained were tall. Then, Mendel self-pollinated the F1 plants and observed that all plants obtained in the F2\xa0generation were not tall. Instead, one-fourth of the F2 plants were short. From this experiment, Mendel concluded that the F1 tall plants were not true breeding. They were carrying traits of both short height and tall height. They appeared tall only because the tall trait is dominant over the dwarf trait. Then he concluded that (T) trait for tallness is dominant and (t) trait for shortness is recessive. | |

Respiration is a vital function of the body."justify the statement explain types of respiration " |
|
Answer» All organisms perform many activities such as growth, reproduction, movement, etc. to perform all these activities of the body we need energy and this energy comes from food we eat after digestion the food is brought to the cell where is broken into carbon dioxide and water to release energy and this process is called respiration all the organisms respire to get energy so respiration is a vital function of body.OThe food material taken in during nutrition is used in cells to provide energy for various life processes. This energy is released during the process of respiration. The oxygen taken in during respiration is\xa0transported to cells for carrying out oxidation of food. This energy is stored in the form of ATP, which is used for the entire working of the body.\xa0Also, the CO2\xa0released during respiration has to be removed immediately out of the body.So without respiration, the body will not get any energy to function in any way. Hence it is a vital function or process of the body. If respiration doen\'t take place in our body so we can\'t survive as well as the breaking down of food doesn\'t took place so the respiration is a vital and important function of our body |

Why sky appears to be blue |
|
Answer» The sky appears to blue because our eye is very attractive to see the colour blue and in the atmosphere blue light is More scattered then the other light so our sky appears blue Cornea What is eyes The molecules of air and other fine particles in the atmosphere have smaller size than the wavelength of visible light. These are more effective in scattering light of shorter wavelengths at the blue end than the light of longer wavelength at the red end. Thus, the blue colour is due to the scattering of sunlight through fine particles in air. By nature |

Differentiate between metal and non-metal according to its chemical properties. |
|
Answer» \t\xa0Metal1. Metals are electropositive.2. They react with oxygen to form basic oxides.3. These have ionic bonds.4. They react with water to form oxides and hydroxides. Some metals react with cold water, some with hot water, and some with steam.5. They react with dilute acids to form a salt and evolve hydrogen gas. However, Cu, Ag, Au, Pt, Hg do not react.6. They react with the salt solution of metals. Depending on their reactivity, displacement reaction can occur.7. They act as reducing agents (as they can easily lose electrons).\xa0Non-metal1. Non-metals are electronegative.2. They react with oxygen to form acidic or neutral oxides.3. These have covalent bonds.4.They do not react with water.\xa0\xa05. They do not react with dilute acids. These are not capable of replacing hydrogen.\xa0\xa06. These react with the salt solution of non-metals.\xa0\xa07. These act as oxidising agents (as they can gain electrons).\t Metals configuration is 1,2,3 and in Non metals configuration is 4,5,6,7,8. |
