Why burning of wax is chemical change |
| Answer» Burning is a chemical change that involves oxidation thus producing heat and light. When a candle is burnt in air, the mass of the product is increased due to atmospheric oxygen which combines with the carbon and hydrogen of the candle wax during burning to produce water vapour and carbon dioxide. Also, the original properties of the reactants are altered. All these factors prove that the burning of a candle is a chemical change. | |

What is double fertilisation ❓❓❓❓ |
| Answer» Soon after pollination the pollen grains start germinating and form a pollen tube. The pollen tube grows within the style till it reaches the ovary.On reaching the ovary it enters the ovule through an opening called micropyle. In the meantime, two male gametes are formed in the pollen tube. One of the male gametes fuses with the egg, the process is called syngamy. The product formed is termed as zygote. The other male gamete fuses with the two polar nuclei, one from each end of embryo sac, to form endosperm nucleus. This process is called triple fusion. In this process three nuclei, two polar nuclei and one male gamete is involved, so it is called triple fusion. Thus, inside each embryo sac two fusions, i.e., syngamy and triple fusion take place. This mechanism of two fusions occurring in an embryonal sac is called double fertilisation. After fertilisation, the ovule develops into seed and the ovary develops into a fruit. | |

What is partial equation method ? with example |
| Answer» Partial Equation MethodEquations are balanced by partial equation method when equations contain many reactants and products and hence cannot be balanced by the hit and trial method.In this method the overall reaction is assumed to take place through two or more simpler reactions, which can be represented by partial equations.The steps involved are:\tThe given chemical equation is split into two or more partial equations.\tEach partial equation is separately balanced by the hit and trial method.\tThese balanced partial equations are multiplied with suitable coefficients in order to exactly cancel out those common substances which do not appear in the overall chemical equations.\tThe balanced partial equations so obtained, are added to arrive at the balanced chemical equation. | |

Describe an activity to show the presence chlorophyll is needed for the process of photosynthesis |
| Answer» First of all, we need to take a\xa0potted plant with variegated leaves like croton and keep it\xa0a dark region, away from sunlight for 3 days.\xa0This will halt photosynthesis and destarch the plant.Next\xa0keep this plant in sunlight for 6-8 hours. The plant can now carry out photosynthesis and produce starch.Next,luck a leaf from this plant and mark the green areas in it and trace them on a sheet of paper. Mark the regions as green and yellow. . As can be deduced, the green areas contain chlorophyll which is absent in the yellow areas.\xa0Next immerse the leaf in boiling alcohol so as to decolourise it. he leaf slowly loses its green color, which goes into the alcohol.Dip this decolorized leaf in iodine solution using a pair of forceps. Now remove the leaf from iodine solution and rinse it in distilled water. Remove the leaf from distilled water and keep it on a petri dish. Two color regions are visible in the leaf. They are reddish brown and blue-black.Compare this leaf with the previously traced drawing on the graph paper. een parts of the tracing and blue-black regions of the leaf coincide. Similarly the reddish brown regions in the leaf coincide with the yellow areas on the traced figure. we can conclude that the earlier green parts of the leaf turn blue-black whereas the yellow parts have become reddish brown. Green parts of the leaf possess chlorophyll; hence they carry out photosynthesis and produce starch, which turns blue-black with iodine. The yellow regions of the leaf cannot carry out photosynthesis since they lack chlorophyll and hence no starch is produced here. | |

Name some vestigial organs present in human body. |
|
Answer» Outer surface of ear Vestigial organs are the organs that have no apparent function and are considered to be the residual parts from the past ancestors.ollowing are a few examples of vestigial organs:SinusesHuman cheekbones hold the maxillary sinuses. The face consists of pockets of air called sinuses. They are lined by a thin layer of mucosa. It has no significant use but infection can lead to sinusitis.AppendixIt is one of the most commonly known vestigial organs. This finger-like tube closed at one end arises from the vermiform process. In prime ancestors, the appendix is believed to have brought about the digestion of cellulose. Today, scientists predict that the appendix may play a role in digestion by bacteria.CoccyxIt forms the last part of the vertebral column, the residue of the lost tail and is often termed as the tailbone. It is observed during human embryogenesis. This formed as the centrepiece of the ‘theory of recapitulation’.Wisdom ToothForms the third set of molars in our buccal cavity. They may have been significant in the past(chewing rough and raw food) but in modern times, as they are inaccessible and remote, it causes pain and infection. |

can you help me how to study science and tips for board exam please |
| Answer» Don\'t fall for the magical tips you hear about everywhere. It is honest and hard work which counts at the end of the day. People out there who are giving tips have themselves learned them after completing the examination. Most of it are eyewash. As for the preparation of science, you should begin by charting out a comprehensive plan. Get to know about the chapters in the syllabus and the average marks assigned to each of them. Read from the beginning. Literally. First page first, first line first and so on. Try to understand the subject matter and don\'t rush through the text. Use highlighter to mark the important point. Discuss with the teachers in topics you are facing difficulty. Once you complete a chapter, don\'t leave it to move ahead. Revise it regularly using your notes along with reading next chapters. If you are not good at numericals, get a coaching. It would certainly help you to learn the fundamentals. At last, have trust in Almighty GOD and do the best you can. I hope and pray for your success. May you come off with flying colours. Aameen | |

How the force arises in magnet to attract an iron piece from a distance? |
|
Answer» Only in artificial megnet can arise the attraction noy natural When you rub a\xa0piece\xa0of\xa0iron\xa0along a\xa0magnet, the north-seeking poles of the atoms in the\xa0iron\xa0line up in the same direction. The\xa0force\xa0generated by the aligned atoms creates a\xa0magnetic\xa0field.\xa0Magnetic force\xa0obeys an inverse square law with\xa0distance. ... If the\xa0distance\xa0between two\xa0magnets\xa0is doubled the\xa0magnetic force\xa0between them will fall to a quarter of the initial value. (F/4) If the\xa0distance\xa0between two\xa0magnets\xa0is halved the\xa0magnetic force\xa0between them will increase to four times the initial value. |

Difference between laws and theory. |
| Answer» A hypothesis\xa0is\xa0a limited explanation\xa0of\xa0a phenomenon; a scientific\xa0theory is\xa0an in-depth explanation\xa0of\xa0the observed phenomenon. A\xa0law is\xa0a statement about an observed phenomenon or a unifying concept, according to Kennesaw State University.\xa0A\xa0theory does\xa0not change into a scientific\xa0law\xa0with the accumulation of new or better evidence. A\xa0theory\xa0will always remain a\xa0theory; a\xa0law\xa0will always remain a\xa0law. Both theories and\xa0laws\xa0could potentially be falsified by countervailing evidence. Theories and\xa0laws\xa0are also distinct from hypotheses. | |

What do u understand by electromagnetic induction? |
|
Answer» The process of generation of electrical energy using magnetic energy is called electromagnetic induction. Actually, when an armature is rotated in the vicinity of magnetic field it give rise to the electromotive force. The production of electricity from magnetism is known as electromagnetic induction.Electromagnetic\xa0or magnetic\xa0induction\xa0is the production of an electromotive force (i.e., voltage) across an electrical conductor in a changing magnetic field. Michael Faraday is generally credited with the discovery of\xa0induction\xa0in 1831, and James Clerk Maxwell mathematically described it as Faraday\'s law of\xa0induction.Let us move the wire AB upward rapidly between the poles of the horseshoe magnet. When the wire is moved up, there is\xa0deflection in the galvanometer pointer shows a current is produced in the wire AB momentarily which causes the deflection in galvanometer. |
