Why graphite is good conducter of electricity |
| Answer» Graphite is a good conductor of electricity. Its structure is the main reason for this property. Each carbon atom in graphite is directly linked to only three carbon atoms through covalent bonds. Therefore, out of the four valence electrons in a carbon atom, only three are used for bonding and the fourth is relatively free and can move from one carbon atom to the other. These free electrons make graphite a good conductor of electricity. | |

how fish seprat oxygen from water in respiration time |
| Answer» Fish are the aquatic vertebrates which respire through structures called as gills. This is called as branchial respiration.\tGills are present on either side of the head and are supplied by rich blood vessels.\tFish obtain oxygen dissolved in water.\tDuring respiration, water enters the body through mouth, passes through gills and comes out of the operculum.\tExchange of gases takes place in the gills of fish supplied by numerous blood vessels.\tThey accept oxygen into the body and expel out carbon dioxide.\xa0 | |

Difference between Endothermic and exothermic reaction |
|
Answer» \tEndothermic ReactionExothermic ReactionA reaction that the system absorbs energy from its surrounding in the form of heat.A reaction that releases energy from the system in the form of heat.The energy is absorbed from the surround into the reactionThe energy is released from the system to its environment.Energy in the form of heatEnergy is released as heat, electricity, light or sound.Melting ice, evaporation, cooking, gas molecules, photosynthesis are few examplesRusting iron, settling, chemical bonds, explosions, nuclear fission are few examples.\t In endothermic reaction, heat is absorbed but in exothermic reaction, heat is evolved |

Why do we use h+ ions to know the pH of a solution, why do we not use oh-? |
| Answer» In common usage, the term hydrogen ion is used to refer to the hydrogen ion present in water solutions, in which it exists as the combined molecule H ·H O.The formula H ·H O is also commonly written as H O and denotes the hydronium or oxonium ion. The amount of hydrogen ion present in a water solution is used as a measure of the acidity of a substance; the higher the concentration of hydrogen ion the more acidic the solution and the lower the pH. | |

What are phytohormone mention any 3function |
| Answer» Hormones present in the plant are called as phytohormones. Phytohormones help in coordinating growth, development and response of the plant to the environment. Hormones are the chemical compounds released by stimulated cells. Hormones diffuse all around the cell.Different hormones secreted by the plant are auxins, gibberellins, cytokinins, abscisic acid.*Auxins are the hormones synthesised at the tip of the stem. These help the plant in growth by cell elongation.*Gibberellins are hormones that help in the growth of the stem, seed germination, bolting, and flowering.*Cytokinins are hormones present in the areas of rapid cell division, such as fruits and seeds. They also promote the opening of the stomata.*Ethylene is the hormone which brings in the ripening of fruits.*Abscisic acid is a hormone that inhibits the growth in various parts. It is also responsible for the closure of stomata. | |

How impulses are transmitted through synapse |
| Answer» There are two types of synapses - electrical synapses and chemical synapses.Conduction and transmission of nerve impulse across a synapse : The theory of chemical transmission or synaptic transmission states that a chemical substance, acetylcholine, is liberated at the synapse and it diffuses through the synaptic transmission occurs in the following way :(a) Release of a neurotransmitter substance at the tip of axon from the synaptic vesicles through presynaptic membrane.(b) Diffusion of this chemical substance, acetylcholine cross the synaptic cleft.(c) Combination of acetylcholine with a chemireceptor on the post synaptic membrane.(d) Depolarization of the post synaptic membrane by neuro-transmitter substance initiate a fresh impulse or action potential passing through the neurons.(e) Inactivation of acetylcholine by an enzyme acetylcholine esterase in the post synaptic membrane.\xa0 | |

Find the no. Of electron in 1coulomb charge. |
|
Answer» The charge on an electron is negative and it is -1.6⨯10-19 coulomb therefore, 1 C charge is carried by 1/ (-1.6⨯10-19) = 6.25 ⨯ 1018 electrons. Hence if 1 A current flows through a conductor, it implies that 6.25 ⨯ 1018 electrons pass per a second across the cross section of the conductor. 1.6 into 10 raise to power -19 no.of electrons r present in one coulomb of charge |
