Difference between cell wall and plasma membrane |
|
Answer» The first difference is that the cell wall is only present in the animal cell but the plasma membrane is present in both plants and animals and the second difference is that the plasma membrane is a living part of the cell where as the cell wall is composed mainly of cellulose and is non living and the third difference is that the plasma membrane is selectively permeable but the cell wall is totally permeable Cell wall is present in only plant cell not in animal cell but plasma membrane is present in both animal cell and plant cell. |

A car travelling at 20 km/ hr speed up to 60. km/ hr in 6 sec what is its acceleration |
|
Answer» Here the formula for finding the acceleration = v-u/tWhere. V= final velocity U= intial velocity T= timeSo, U= 20 km/h = 20x5/18= 50/9 m/s. {1000m/3600sec = 5/18m/s}v= 60 km/h = 60x5/18= 50/3 m/st= 6 sa= v-u/t = 50/3-50/9÷6 = 100/9÷6 = 100/9×1/6 = 50/27 m/s^2 Acceleration nikal lo answer a jayega |

Why we sprinkle water on roof in summers |
|
Answer» We usually Sprinkle water on a roof in summer season because the temperature is very much in the summer season and we feel very hot as we all know that evaporation causes cooling because it takes a latent heat of vaporization from the object that it is in contact with so when we sprinkle water on the roof in summer then the water will evaporate the latent heat from the roof and get evaporated and make the roof cool Becase the roof becomes hot in summers and when we sprinkle water The water become hot amd get evaporated |
|
| 2763. |
The rate of diffusion varies in solids, liquids and gases. Why? |
| Answer» Because of the interparticle force of attraction.The interparticle force of attraction is higher in solids, less in liquids and negligible in gases.So particles moves very slowly in solids. hence it takes more time. | |

Why our skin shrink when we wash cloths for a long peroid of time |
|
Answer» Clothes are washed with soap or detergent solution. This solution is hypertonic as compared to osmotic concentration of our skin cells. The washing solution, therefore results in exosmosis in the skin cells that come in contact with it for some time. Due to this reason, the skin over the fingers shrink while washing clothes for a long time. Ur answer is not complete No Because of acid in the washing powder |
|

What is DNA and RNA ?What is the function of DNA and RNA? |
| Answer» DNA (Deoxyribonucleic Acid) is a double helix, which looks very much like a twisted ladder. Each "rung" of the ladder (the part you step on) is a nitrogenous base. The sides of the ladder are made of sugar and phosphate groups, with the sugars being the ones that hold the nitrogenous bases in place. Each nitrogenous base pairs ONLY with another, never crossing over. (Adenine and Thymine, Guanine and Cytosine). It\'s a bit like a puzzle where the pieces will only fit together that way. RNA is like half of the ladder. The basic structure is the same, but there is only one nitrogenous base along it. However, RNA does not have the base Thymine. It has Uracil instead. Also, the sugar in DNA is deoxyribose while the sugar in RNA is ribose. | |
