How the exchanges of gases take place in our respiratory system |
| Answer» Alveoli are the air sacs of the lungs. They have thin walls surrounded by blood capillaries (another layer of simple squamous epithelium). Gas exchange occurs in the alveoli. During inhalation, oxygen gas is in higher concentration in the alveoli than in the blood and so it diffuses into the blood through this thin layer of cells. During exhalation, carbon dioxide is in higher concentration in the blood than in the alveoli and so it diffuses into the alveoli through this thin layer of cells. | |

What is archimedes principle?? |
|
Answer» When an object immersed wholley or partially in a liquid it displaced some liquid and the displaced liquid exert and upward force is called buoyant force and this property of liquid is called buoyancy when the buoyant force = weight of displaced liquid =apparant loss in weight Archimedes principle state that the substance which is immersed partially or fully in water experienced a force i.e.. BOUYONT FORCE which is equal to the amount of water displaced by the substance.In short , Archimedes Principle =Bouyont force acted on substance = amount of water displaced by substance Archimedes\' principle, physical law of buoyancy stating that any body submerged in fluid at rest is acted upon by an upward force. |

What is electrostatic body or static electricity |
| Answer» Static electricity refers to an imbalance between the electric charges in a body, specifically the imbalance between the negative and the positive charges on a body. The imbalance in the charge is introduced by physical means. One of the most common causes of static electricity is the contact between solid objects. It was mentioned earlier that the movement of protons is not possible and the only movement of electric charge seen in static electricity is electrons. | |

What happens to the glucose which enters the nephron tubule alongwith the filtrate? |
| Answer» When\xa0glucose enters nephron along with filtrate, it goes down the renal tubule by the action of cilia. The tubular cells absorb\xa0glucose, amino acids, salts, etc. These are then passed into the capillary blood cells using the process of diffusion.\xa0Renal\xa0glucose\xa0reabsorption\xa0is\xa0the part of\xa0kidney\xa0(renal) physiology that deals with the retrieval of filtered\xa0glucose, preventing it from disappearing from the body through the urine. ... Once\xa0in\xa0the tubule wall, the\xa0glucose\xa0and amino acids diffuse directly\xa0into\xa0the\xa0blood\xa0capillaries along a concentration gradient. | |

Why translation is essential for plants body |
| Answer» The transport of soluble products of photosynthesis is known as translocation. Translocation in plants occurs by means of the vascular tissue known as phloem. Translocation is necessary because without it, the food prepared by the leaves cannot reach other parts of the plant. In plants, the synthesis of sugars takes place in the leaves by the process of photosynthesis. Hormones are synthesised away from their target site. | |

\'bile juice do not contain any enzyme \'what us essantial for digestion .justify the statement |
| Answer» Bile does not contain any enzyme but it is essendal for digestion because bile is alkaline and contain salts which helps to emulsify the fat present in the food. So, the bile perform two functions:\tThe food coming from the stomach is acidic and has to be made alkaline for the pancreatic enzymes to act.\tThe bile salts breakdown the fat present in the food into smaller globules. This increases the efficiency of enzymes in the small intestine to digest the food effectively. | |

define ohms law what is the condition required to obey ohms law |
| Answer» Ohm\'s Law:It states that the current through any two points of the conductor is directly proportional to the potential difference applied across the conductor provided that the physical conditions remains constant.Unit:It is measured in ohm represented as Ω.Explanation:When an electric potential difference is applied across the conductor, the current passes through it. Here some of the current is apposed by the resistance of the conductor in the circuit. Thus Ohm\'s Law is the relation between current, voltage and resistance.According to Ohm\'s Law:V α IV = I RWhere R (resistance) is the constant or proportionality.Ohm\'s Law is applicable only if all the physical conditions for example temperature, material or dimensions of the wire remain constant. | |

Define 10% law of energy transfer |
| Answer» The 10 percent law was given by Raymond Lindeman which demonstrates the transfer of energy that takes place from one trophic level to the other.According to the law, during the transfer of energy from one trophic level to another, only 10℅ is available for the next trophic level as the other 90℅ is lost as heat to the surroundings.\xa0For example: In a given simple food chain-Primary producer( Plants) ----> Primary consumer( deer) -------> Secondary consumer( Lion), the primary producers form the first trophic level, the primary consumers the second and so on. In this example, if the first level gets 1000kcal of energy, the next one gets 100 kcal while the third gets 10 kcal. | |
