Define isotopes. |
|
Answer» Isotopes\tAtoms of the same element differing in the number of neutrons in their nuclei are known as isotopes. Thus, isotopes of an element have the same atomic number but different atomic mass numbers.\tIsotopes are identified by their mass numbers.\tFor example, the isotopes of carbon are referred to as carbon-12, carbon-13 and carbon-14. Atom of the same element having same atomic no.but different in mass no. |

What is the process of villi? |
|
Answer» Helps in absorption of food in small intestine Villi are small finger-like outgrowths present that help in the process of absorption. These are located in the inner walls of the small intestine. Their function is to increase the surface area of the small intestinal wall for absorption of the digested food. Villi is finger like projection prensent in both small and large intestine. |

Respiration process by mitochondria. |
|
Answer» The process by which a living being utilizes the food to get energy is called respiration. Respiration is an oxidation reaction in which carbohydrate is oxidized to produce energy. Mitochondrion is the site of respiration and the energy released is stored in the form of ATP (Adenosine triphosphate). ATP is stored in mitochondria and is released as per need. Yes by aerobic respiration it converts to co2 h20 and energy |

What are fossils ? What do they tell us about the process of evolution ? |
|
Answer» Fossils are remains or impressions of organisms that lived in the remote past.\xa0Fossils provide the evidence that the present animal have originated from previously existing ones through the process of continuous evolution.\xa0Fossils can be used to reconstruct evolutionary history of an organism. The distribution pattern of fossils shows that the ancient fossils present in the bottom rocks are simple, while the most recent fossils found in the upper strata are more highly evolved. It means fossils form and become more and more complex as we proceed from earliest to recent rocks.\xa0It gives us an idea of time in history when different species were formed or became extinct.\xa0Fossil also help to trace the evolutionary history of some animals. Fossil fuels are non renewable sources of energy. For eg. Petroleum, Coal,e.t.c. are some examples of fossil fuels. And they do not tellUs about any evolution. |

What is reflection. Write the laws of reflection. |
|
Answer» Very good ? The incident ,normal and reflected ray to the point of incidence all lie in the same plane. the principle that when a ray of light, radar pulse, or the like, is reflected from a smooth surface the angle of reflection is equal to the angle of incidence, and the incident ray, the reflected ray, and the normal to the surface at the point of incidence all lie in the same plane. Angle of incidence is equal to angle of reflection Reflection of light is defined as the change in the path of light without changing the medium when it strikes on a surface. |

why covalent compounds are generally bad conductors of electricity? |
|
Answer» Covslent compounds are generally poor conductors of electricity because they do on produce ions in solution or on melting Current is movement of charged ions and electricity is conducted in water from one place to the other by the movement of ions. Since there are no free ions in a covalent compound, they don\'t conduct electricity. |

What type of information do we get from chemical equations? |
| Answer» A balanced chemical equation can provide the following information :\tThe reactants and products through their symbols and formulae.\tThe ratio of molecules of reactants and products.\tAs molecular masses are expressed in unified mass (u), the relative masses of reactants and products are known from the equation.\tIf the masses are expressed in grams then the equation also gives the molar ratios of reactants and products.\tIf gases are involved, we can equate their masses to their volumes and calcu-late the volumes or those gases liberated at given condition of temperature and pressure using molar mass and molar volume relationship.\tUsing molar mass and Avagadro’s number we can calculate the number of molecules and atoms of different substances from the equation. | |

Why does intestine in herbivores are larger than carnivores |
|
Answer» Intestine of herbivores is larger than carnivores because herbivores have to digest heavy food like grass ,leavesetc .. where as carnivorous eat light food which can easily digested by them. Cellulose forms the largest part of the herbivore’s food. Digestion of cellulose takes a longer time, because the enzymes are produced by the ruminant bacteria that live in the gut of the herbivore. Longer small intestine ensures that the food stays for a longer duration and proper digestion is possible. In the case of carnivores, cellulose is not present in the diet, thus the length of small intestine is less. |

What does one mean by exothermic and endothermic reaction? Give example |
|
Answer» In exothermic reaction heat is released along with products where as ln endothermic reaction heat is absorbed Exothermic Reaction: A chemical reaction in which heat is given out is known as exothermic reaction. For exampleC(g) + O2(g) → CO2(g) + Heat EnergyNaOH(aq) + HCl (aq) → NaCl(aq) + H2O(l) + EnergyEndothermic Reaction: A chemical reaction in which heat energy is absorbed is known as endothermic reaction. For exampleN2(g) + O2(g) → 2 NOC(s) + H2O → CO(g) + H2(g) In exothermic heat is released and in endothermic heat is absorbed |

How does chemical coordination |
| Answer» At the cellular level the muscle cells move by changing their shape so that they shorten. Muscle cells have special proteins that change both their shape and theirarrangement in the cell in response to nervous electrical impulses. When this happens, new arrangements of these proteins give the muscle cells a shorter form.When the sense organ in our body is affected, it sends the message to the brain in the form of electrical impulses through the sensory neurons. The brain analyses this message and decides the action to be taken. The brain then sends out instructions to the muscles of the concerned body parts through motor nerves and the concerned body part acts accordingly.\xa0 | |

The process of emulsification in soap??? |
| Answer» Soap molecules have two parts, on is polar head which is hydrophilic (water soluble) carboxylate group and other is non polar tail, which is hydrophobic (oil soluble) hydrocarbon tail. In water, several soap molecules aggregate to form micelles in which hydrocarbon tails are in the interior of cluster and polar heads are at the surface of clusters. The dirt in cloth is due to presence of dust particles in fat or grease which stick to the cloth. In the soap solution, micelles are formed around oil droplets. The hydrophobic part of soap is in the oil droplet and hydrophilic part projects outside like bristiles. The oil drops and micelle are then pulled in water due to hand rubbing or agitation and are washed away. | |

Dervive the relation Rs=R1+R2+R3 |
|
Answer» Thanks you so much yogita ingle....?? Perfect answered Let there be 3 resistance R1, R2, and R3 connected in series. A battery of V volts has been applied to the ends of this series combination. Now suppose the potential difference across the resistance R1 is V1, R2 is V2 and R3 is V3.∴ V= V1+V2+V3 ...(1)Now, suppose the total resistance of the combination be R, and the current flowing through the whole circuit be I.So, applying Ohm\'s law to the whole circuit, we get :V/I = R or V=IR ...(2)∵ The same current is flowing through all three resistances, so by applying Ohm\'s law to three of them seperately, we will get\xa0V1 = IR1V2= IR2 andV3= IR3 ... (3)\xa0Now, putting (3) and (2) in equation (1), we getIR = IR1 + IR2 + IR3i.e IR = I ( R1 + R2 + R3 )⇒ R = R1 + R2 + R3 |
