What is endocytosis? Why is endocytosis found in animals only. |
| Answer» Endocytosis refers to imagination of a small region of plasma membrane, forming an intercellular membrane-bound vesicle. It has been observed in many kinds of animal cells, where the plasma membrane is in direct contact with external medium. Endocytosis is not shown by plant cells because a rigid cell wall is present over the plasma membrane in them. Thus, this process is found in animals only. | |

What will happen to the life of a cell it there was no golgi apparatus? |
| Answer» Golgi apparatus plays the important role of packaging various substances for further use or for storage. If there was no Golgi apparatus, various substances would not be in a position to be transformed in proper forms for further use. Certain substances, like protein and lipid are important for the formation of plasma membrane and hence absence of Golgi apparatus will hamper the formation of new cells during cell division. | |

Why did Rutherford use a gold foil...?? |
|
Answer» It is not malleable it is ductile .due to its ductility he used gold foil Rutherford used gold for his scattering experiment because gold is the most malleable metal and he wanted the thinnest layer as possible.The gold sheet used was around 1000 atoms thick.Therefore, Rutherford selected a Gold foil in his alpha scatttering experiment. |

Derive an expression for the kinetic energy of an object. |
|
Answer» K=1/2mv^2 Consider a body of mass m initially at rest. If on application of force F, it travels a distance s, thenWork done, W = F x sBy Newton\'s second law, F = maW = ma x swhere, a = accelerationUsing equation of motion v2 - u2 =2as, we get(v2-u2)/2 = asW = m x (v2 - u2)/2As intial velocity is zero, W = ½mv2This work done is stored as kinetic energy of the object.So, KE = ½ mv2 |

What is Rutherford model of an atom ? |
|
Answer» The Rutherfords atomic model is that the he experiment on a-ray Rutherford bombarded a-ray (helium nucleus) upon thin gold foil The atom, as described by Ernest Rutherford, has a tiny, massive core called the nucleus. The nucleus has a positive charge. Electrons are particles with a negative charge. Electrons orbit the nucleus. The empty space between the nucleus and the electrons takes up most of the volume of the atom |

What is the diagram of tyndall effect |
| Answer» What is a Tyndall effect?Answer:\xa0This scattering of a beam of light by the particles of a colloid is called the Tyndall effect. When we apply torch light on a galss of milk then the path of the light becomes visible but it is not so in case of water because in milk light is scattered by its very fine particles. See the following diagram:Tyndall effect can be observed when sunlight passes through the canopy of a dense forest. In the forest, mist contains tiny droplets of water, which act as particles of colloid dispersed in air. If is shown in the diagram below: | |

Funtion of cell wall , cytoplasm , nucleus |
|
Answer» Function of nucleus---------------------------------#Nucleus plays an important role in cellular reproduction.In this process, a cell divides to form two new cells .#It determines the cell development and maturity by directing the chemical activities of cell. #It helps in the transmission of hereditary traits frkm parents to offsprings .#It controls all metabolic activities of cell.If it is removed, the protoplasm dries up.Function of cytoplasm-------------------------------------#It helps in the exchange of material between cell organelles.#It acts as a storehouse of vital molecules such as amino acid, glucose,vitamin, iron etc.#It acts as the site for certain metabolic pathways such as glycolysis etc.Function of cell wall---------------------------------#Cell wall permits the cells of plants, fungi and bacteria to withstand hypotonic conditions without burstings.#It has narrow pores, called pits.Through them, fine strands of cytoplasm (cytoplasmic bridges) called plasmodesmata are able to cross the cell walls . Plant cells interact with each other through these cytoplasmic channels. May it helps youu!!!!!!!!!!!!!! Nucleus= it stores the cell\'s hereditary , material , or DNA , and it coordinates the cell\'s activities , which include growth , intermediary , metabolism , protein sythesis , and reproduction on ( cell devision) Cell wall= is only present only plant cell. It protect the cell and it made up of cellulose. |

Write the advantages of Manure over fertilizers |
| Answer» Manure are Natural they are made uo of Cow Dunk, Vegetable Peals,Rotten Fruit,and all Natural things.Fertilizer are Chemically combined with Urea, Phosphorus and all harmful chemicals used in to form fertilizer.So, Manure are good and better then best over Fertilizer.Fertilizer causes soil defection but the manure slowly improve the quality of the soil.Fertilizer works fast but also Harms the Corps.Manure are basically slow than Fertilizer... | |

Why are lichens called dual organism |
| Answer» Lichens are called as dual organisms because they have symbiotic relationship between algae and fungus.Explanation:• Lichens are species that grown from the substrate of fungi in an algae environment• The algae and the fungi are in mutual relationship the algae help them to produce food and the fungus help them to absorb the nutrients• Symbiotic relationship is that the organisms have mutual support and they help each other and they are beneficiary to each other• They are of various size and forms and they are divided into thallus and the filament body parts• Lichens are of variety of colors and this is due to the presence of usnic acid | |

What is the maximum number of electrons which can be accommodated in N shell ? |
|
Answer» 32 electrons is the maximum number of electron thet can be accomodated in N shell. According to the first rule : 2n^2 is the formula to find the max. No. of electronsSo, 2*4^2=32 where n=the no. Of shell like (1,2,3......)Hence the max.electrons could be 32.Now according to octet rule it can carry only 8 as its max. No. Of electrons. 8 |

Show that weight of the earth is 6 times greater than weight of the moon |
| Answer» | |
| 8596. |
Show that the weight of the earth is 6 times greater than weight of the moon |
| Answer» The weight of an object on the moon will be about one-sixth of what is on the earth. Thus, a spring balance which shows the weight of a body to be 6 N on earth will show a weight of only 1 N when taken to the moon. The weight of an object on the moon is less than that on the earth because the mass and radius of the moon are less than that of earth.Suppose we have an object of mass m. let its weight on the moon be Wm, the mass of the moon is Mm and its radius is Rm. now, according to the universal law of gravitation, the weight of the object on the moon will be:Wm = G x Mm x m/Rm2Let the weight of the same object on the earth be We. The mass of the earth is M and its radius is R.We = G x M x m/R2Wm = G x 7.36 x 1022 kg x m / (1.74 x 106 m)2Wm = 2.431 x 1010 G x m i.We = 1.474 x 1011 G x m ii.Dividing both the equations i. & ii.Wm/We = 1/6Weight of the object on the moon / Weight of the object on the earth = 1/6Weight of the object on the moon = (1/6) × its weight on the earth. | |
