Name three amphoteric oxides rather than aluminium and zinc. |
|
Answer» CuO Metals which form an amphoteric oxide are zinc, tin, lead, aluminium and beryllium. e.g., Zinc and aluminium forms zinc oxide (ZnO) and aluminium oxide (Al2\u200bO3\u200b) respectively.Amphoteric oxides react with acids as well as bases. Thus ZnO will react with HCl as well as with NaOH.ZnO+2HCl→ZnCl2\u200b+H2\u200bOZnO+2NaOH→Na2\u200bZnO2\u200b + H2\u200bO |

Definition and explaining of chemical equation |
| Answer» The method of representing a chemical reaction with the help of symbols and formulae of substances involved in it is called a chemical equation.Example: Zinc metal reacts with dilute sulphuric acid to form zinc sulphate and hydrogen gas. This equation is written as: Zn + H2SO4\xa0→ZnSO4 + H2\xa0\tWriting Chemical Equations: \tIn a chemical reaction, the reactants are written on the left hand side and the products on the right hand side of the equation.\tAn arrow (→) pointing towards the products is inserted between the reactants and the products. It also represents the direction of the reaction.\tA single arrow (→) indicates the direction in which the reaction proceeds.\tA double arrow (⥮) indicates a reversible reaction, i.e. the products recombine to form the reactants.\tA plus sign (+) is inserted between two or more reactants or products formed.\tIf reactions are carried out under specific conditions of temperature, pressure, catalyst etc., then these conditions are mentioned on the arrow.The chemical equation can be made more informative by mentioning the physical states of the reactants and products.\tIf gas is liberated as a product then it is represented by an arrow pointing upwards (↑).\tIf the product formed is in the form of a precipitate, it is represented by an arrow pointing downwards (↓). | |

What is calvin cycle |
| Answer» Calvin cycle is also known as C3 cycle or light-independent or dark reaction of photosynthesis. However, it is most active during the day when NADPH and ATP are abundant. To build organic molecules, the plant cells use raw materials provided by the light reactions:1. Energy: ATP provided by cyclic and noncyclic photophosphorylation, which drives the endergonic reactions.2. Reducing power: NADPH provided by photosystem I is the source of hydrogen and the energetic electrons required to bind them to carbon atoms. Much of the light energy captured during photosynthesis ends up in the energy-rich C—H bonds of sugars. | |

How does electrik generator work? |
| Answer» \tElectric generators are based on the principle of electromagnetic induction and converts mechanical energy into electrical energy.\tAn electric generator consists of a rotating rectangular coil placed between the two poles of a permanent magnet.\tThe two rings R1 and R2 are internally attached to an axle. The axle may be mechanically rotated from outside to rotate the coil inside the magnetic field.\tOuter ends of the two brushes B1 and B2 are connected to the galvanometer to show the flow of current in the given external circuit.\tWhen the axle is rotated, arm AB moves up (and the arm CD moves down) in the magnetic field produced by the permanent magnet. Let us say that the coil ABCD is rotated clockwise. By applying Fleming’s right-hand rule, the induced currents are set up in these arms along the directions AB and CD. Thus, an induced current flows in the direction ABCD. If there are more turns in the coil, the current generated in each turn adds up to give a large current through the coil.\tAfter half rotation, CD and AB reverse direction, and thus, CD starts moving up and AB starts moving down. As a result, the directions of the induced currents in both the arms change. Such a current which changes direction after equal intervals of time is called an alternating current. Thus, this device is called an AC generator.\tTo get a direct current, a split-ring type commutator must be used. The generator is thus called a DC generator.\tThe difference between direct and alternating currents is that the direct current always flows in one direction, whereas the alternating current reverses its direction periodically.\t | |

Complete digestion of food occurs in the small intestine .Justify the statement |
| Answer» The small intestine is where most chemical digestion occurs. After the stomach empties the food and juice mixture into the small intestine, the juices of two other digestive organs mix with the food to continue the process of digestion. One of these organs is the pancreas. It produces a juice that contains a wide array of enzymes to break down the carbohydrate, fat, and protein in food. Other enzymes that are active in the process come from glands in the wall of the intestine or even a part of that wall.The liver produces yet another digestive juice—bile. The bile is stored between meals in the gallbladder. At mealtime, it is squeezed out of the gallbladder into the bile ducts to reach the intestine and mix with the fat in our food. The bile acids dissolve the fat into the watery contents of the intestine, much like detergents that dissolve grease from a frying pan. After the fat is dissolved, it is digested by enzymes from the pancreas and the lining of the intestine.Digested food broken down in the small intestine is the size of molecules and can now pass through the villi into the blood stream through the process of diffusion.Digested molecules of food, as well as water and minerals from the diet, are absorbed from the cavity of the upper small intestine. Most absorbed materials cross the mucosa into the blood and are carried off in the bloodstream to other parts of the body for storage or further chemical change. As already noted, this part of the process varies with different types of nutrients. Finally, all of the digested nutrients are absorbed through the intestinal walls. The waste products of this process include undigested parts of the food, known as fiber, and older cells that have been shed from the mucosa. | |

What is the advantage of having 4chambered heart ??? |
|
Answer» Answer:The advantages of having four chambered heart is that:Explanation:* the four chambered heart\'s left half is separated from right half which prevent mixing of oxygenated and deoxygenated blood*it allows the efficient supply of oxygenated blood to all parts of the body . this is useful in animals which have high energy needs such as mammals ,birds ,etc The four chambered heart is present in warm blooded animals as they cannot tolerate the mixing of oxygenated and deoxygenated blood so to prevent it from mixing four chambered heart is present The\xa0four-chambered heart\xa0has a distinct\xa0advantage\xa0over simpler structures: It allows us to send our "dirty" blood to the cleaners-the lungs-and our "clean" blood to the rest of the body without\xa0having\xa0to mix the two. That system is very efficient.\xa0In\xa0four chambered heart, left half is completely separated from right half by septa. It serves following two purposes (a) ensures complete segregation of oxygenated and deoxygenated blood (i.e., no mixing). (b) allows a highly efficient supply of oxygenated blood to all parts of the body.a |

What os mean by periodic classifisatioj |
| Answer» In 1913, Henry Moseley proved that the atomic number is the fundamental property rather than its atomic mass.Modern Periodic Law: Properties of elements are a periodic function of their atomic numbers.The periodic table, based on the Modern Periodic Law is called the Modern Periodic Table.The horizontal rows in the Modern Periodic Table are called periods.The Modern Periodic Table consists of seven periods which are numbered from 1 to 7.In each period, a new shell starts filling up. The period number is also the number of shell which starts filling up.The vertical columns are called groups and consist of eighteen groups numbered from 1 to 18.Elements having the same number of valence electrons are present in the same group. | |

How does an AC generator start initially , as there is no movement in the armature |
| Answer» In electrical engineering, an\xa0armature\xa0is the component of an\xa0electric\xa0machine which carries\xa0alternating current. The\xa0armature\xa0must carry current, so it is always a conductor or a conductive coil, oriented normal to both the field and to the direction of motion, torque (rotating machine), or force (linear machine).\xa0As one side of the coil moves up through the magnetic field, a potential difference is induced (created) in one\xa0direction. As the rotation continues and that side of the coil moves down, the induced potential difference reverses\xa0direction. This means that the alternator produces a\xa0current\xa0that is constantly changing. | |

What is the role of ciliary muscles? |
| Answer» Ciliary Muscles:\tThe ciliary muscle to which eye lens is attached helps the eye lens to change its focal length by changing radii of curvature of eye lens.\tWhen the eye is focused on a distant object, the ciliary muscles are relaxed so that the focal length of eye lens has its maximum value, which is equal to its distance from the retina.\xa0\tThe parallel rays coming into the eye are then focused on the retina and we see the object clearly.\tWhen the eye is focused on a closer object the ciliary muscles are strained and focal length of eye-lens decreases. The ciliary muscles adjust the focal length in such a way that the image is formed on retina and we see the object clearly. | |
