Why the position of hydrogen was not fixed in mendeleeve\'s periodic table. |
|
Answer» Because hydrogen could easily losse one electron to form a poditive cation as well as it existed as diatomic molecule as group 17 elements Yea Because of Hydrogen \' s anamolous behaviour. It shows properties of both metal and non metal, it can do both lose and gain electrons . Because Mendeleev arranged the elements in terms of their increasing atomic masses as well as their similar chemical properties Because mendeeleev arrange the elements according to increase atomic masses that\'s why a correct position of hydrogen did not explain in mendeeleev periodic table |

Why is diffusion insufficient to meet the oxygen requirements of multicellular organisms like humans |
|
Answer» Diffusion, in multicellular organisms, is not enough to meet energy requirements of innermost cells of its body, as O2 reaches those cells gradually through this method. Because human has a very complex body structure and it take nearly 3 years to transfer o2 from heart to legs. Size of multicellular organism is very large as compare to unicellular organism and diffusion is passive mode of transportation of substance and can transfer gases up to a small distance only Because multicellular organisms has complex working systems which need more energy(oxygen) at a time where as diffusion is a very slow process which can\'t be able to fulfill the needs of sufficient oxygen to the body |

Compute the no. Of electrons passing per minute through an electric bulb of 60w,220v |
| Answer» Given :-Power (P) = 60 WVoltage (V) = 220 VTime (T) = 1 min = 60 SecCharge of an electron (q) = 1.6 × 10⁻¹⁹ CTo Calculate :-Numbers of electron (n) = ???Formula to be used :-= I × T/Q ..... Eq (i)Solution :-Since in this equation/case we do not know the value of I, therefore our prime aim is to find the value of I using the formula,⇒ I = P/V⇒ I = 60/220⇒ I = 3/11 ASubstituting this value of I and the value of t and in eq (i), we get⇒ n = 3/11 × 60/1.6 × 10⁻¹⁹⇒ n = 180 × 10¹⁹/11 × 1.6⇒ n = 1.02 × 10²⁰ Electrons.Hence , the Numbers of electron (n) is 1.02 × 10²⁰ Electrons. | |

Should the resistance of an ammeter be low or high give reason |
|
Answer» The resistance of an ammeter should be low as if the resistance will be low then it will allow the current to pass through it then only it will be able to measure the current. so, an ammeter should be of zero resistance The resistance of an ammeter be low .an ammeter has to be connected series with the circuit to measure current. In case its resistances is not very low ita inclusion in the circuit will reduce current to be measured an ideal ammeter is one which has zero resistance ?? |

Differentiate between budding and fission |
|
Answer» BUDDING = found in unicellular and multicellular organisms. A small cytoplasmic outgrowth arises in body of organism known as BUD due to repeated division of cells ---> detach to form new offspring. Eg :- Hydra, yeast, etc.......FISSION = found only in unicellular organisms. Parent body divides into two or more daughter cells. Eg :- amoeba, leishmania, paramoecium, etc. Budding is a asexual mode of reproduction in which new organism is formed by breaking down of outgrowth from it\'s body parts but I\'m case of fission organism is formed when nucleus is divided. |

Why photosynthesis proces considered as endothermic reaction? |
|
Answer» Because a certain amount of energy is abosrbed during this process, that\'s why it is known as endothermic reaction In photosynthesis heat is absorbed from sunlight, that\'s why it is known as endothermic reaction. B coz it absorbs light energy from sun. It is endothermic because it can take place in the presence of sunlight and energy is absorbs through the green pigment chlorophyll.Reaction..... C6 H12 6O2 --------- 6CO2+ 6H2O+energy Yes, photosynthesis is a endothermic reaction because it can\'t occur without energy (from sun) . The light energy absorb by a green pigment. |
