How does human get nutrition explain |
| Answer» 1. In humans, digestion of food takes place in the alimentary canal, made up of various organs and glands.2. In the mouth, food is crushed into small particles through chewing and mixed with saliva, which contains amylase for digesting starch.3. Food passes through the pharynx and oesophagus to reach the stomach. Gastric juice contains pepsin (for digesting proteins), HCl and mucus.4. In the small intestine, carbohydrates, proteins and fats are completely digested into glucose, amino acids, fatty acids and glycerol.5. The villi of the small intestine absorb the digested food and supply it to every cell of the body.6. The undigested food is removed from the body through the ****. | |

How ammonia release OH- ions |
| Answer» Ammonia\xa0doesn\'t contain\xa0hydroxide ions, but it reacts with water to\xa0produce\xa0ammonium\xa0ions\xa0and\xa0hydroxide ions. ... A weak base is one which doesn\'t convert fully into\xa0hydroxide ions\xa0in solution. When a weak base reacts with water, the position of equilibrium varies from base to base.\xa0Ammonia releases hydroxide ions\xa0when it dissolves, but only because the\xa0ammonia\xa0steals a proton from a water molecule: ... In the case of NaOH, the\xa0hydroxide ions\xa0come from the crystal lattice of the solid, and in the case of NH3\xa0they come from dissociated water molecules whose protons have combined with NH3\xa0to form, NH4+. | |

Why does metal conduct electricity |
|
Answer» Metals can conduct electricity because of the free electrons present in it. These free electrons will move in a particular direction ( the direction of the flow of current ) when electricity is passed through it this conducting electricity. Metal conduct easy because most of the metals will lose electrons , we have already studied the flow of electrons is electricity. Therefore in metals electrons can easily move . So that the metals are good conductor of electricity Metal conduct electricity because it is a good Conductor of electricity the close packing of the metal ions in the\xa0latticethe\xa0delocalised electrons\xa0can carry kinetic energy through the lattice.Picture 1.4 A\xa0cool lattice. If we heat the left hand end, then the energy will be\xa0carried along\xa0by\xa0conduction.Ionic vibrationsThe positive metal ions in a metal structure are packed closely together in a symmetrical geometric arrangement. They don’t move from their position in the lattice but they are constantly\xa0vibrating. If a metal is heated, the positive metal ions vibrate more vigorously. These ions collide with neighbouring ions and make them vibrate more vigorously too. In this way, the energy is\xa0passed, or\xa0conducted, through the metal. Substances\xa0conduct electricity\xa0because they contain charged particles that are able to move. When a voltage is applied to a\xa0metal, the delocalised electrons travel through the lattice structure. The movement of these charged particles forms an electric current. Electric\xa0current is the flow of electrons in a wire. In\xa0metals, the outer electrons of the atoms belong to a \'cloud\' of delocalised electrons. They are no longer firmly held by a specific atom, but instead they\xa0can\xa0move freely through the lattice of positive\xa0metal\xa0ions. Metals\xa0are good conductors of heat. |

List any two parts of nephron and mention it\'s function?? |
|
Answer» Bowman capsule ANSWER\xa0A nephron\xa0is the basic filtration unit of the kidney. It is a cluster of thin-walled blood capillaries.\xa0There are\xa0different parts of the nephron in which the formation of urine take place which is the main function of the kidney.\xa0\tBowman\'s capsule and the glomerulus are together called as the glomerular apparatus.\xa0\tThere are afferent and efferent arterioles which bring and carry the blood way.\xa0\tThe blood is filtered by the glomerulus and enters the Bowman\'s capsule where the podocytes help in the filtration and the glomerular filtrate is formed.\xa0\tWhen the glomerular filtrate comes to the proximal tubule then the essential nutrients are reabsorbed.\xa0\tThere are two limbs of the loop of Henle, ascending and descending limb.\xa0\tThe countercurrent exchange mechanism\xa0occurs which help in the regulation of the water and ions in the blood.\xa0\tWhen the glomerular filtrate is in the proximal tubule creatinine, uric acid are\xa0secreted in it.\xa0\tWhen the filtrate goes to the distal convoluted tubule urea, potassium ion and some hydrogen ions are secreted in it.\xa0\tThe urine which is formed is transported by the collecting tubules to the renal pelvis.\xa0\tThe urine is transported out by the ureters to the urinary bladder to store and excrete the urine from urethra. |

What is valves |
|
Answer» Vavles present in vein vescles Because Vavles working is that flows of blood in backward direction from body to heart. Valves are flap-like structures present in heart that allow blood to flow in one direction. The valves control the flow of blood through the heart by opening and closing during the contractions of the heart. The opening and closing functions of the valves are controlled by pressure differences generated within the heart, as well as some muscles located within the heart. The heart has two kinds of valves, atrioventricular and semilunar valves. \tThe two atrioventricular (AV) valves, which are between the atria and the ventricles, are the mitral valve and the tricuspid valve.\tThe two semilunar (SL) valves, which are in the arteries leaving the heart, are the aortic valve and the pulmonary valve.Thus there are\xa0four valves in all. |

Why rainbow is formed? |
| Answer» \tA rainbow is a natural spectrum of sunlight in the form of bows appearing in the sky when the sun shines on rain drops.\tIt is combined result of reflection, refraction and dispersion of sunlight from water droplets, in atmosphere.\tAlways it formed in the direction opposite to the sun.\tTo see a rainbow, the sun must behind us and the water droplets falls infront of us.\tWhen a sunlight enters into a spherical rain¬drop, it is refracted and dispersed. The different colours of light bent in different angles.\tWhen different colours of light fall on the back inner surface of drop, it (water drop) reflects (different colours of light) internally (total internal reflection).\tThe water drops again refracts the different colours, when it comes out from the raindrop.\tAfter leaving this different colours from the raindrop as rainbow, reach our eye. Thus, we see a rainbow. | |
