A person take concentrated solution of salt,after some time he starts vomiting, why? |
| Answer» When a solution containing excess of salt is taken, then due to osmosis water will move into the intestine, putting pressure on the intestinal walls. This also causes nausea. The intestinal wall is not able to tolerate this strain, and hence this excess water retention causes vomiting | |

Why air is considered as a mixture and not a compound |
|
Answer» Air contains oxygen and nitrogen as its major constituents. These gases retain their properties in air. So the air is called a mixture. Air is considered a mixture because in air there is many gases combined together in any proportion and we know that mixture is a substance consist of two or more two substance in any proportion Air is considered as a mixture because it is made up of two or more than two types of atom like it contains hydrogen, oxygen, nitrogen etc. And these all substances are not in fixed ratio. Sia you are a genius Air contains many gases .In Science anything that contains many items is called mixture . That is why air is mixture |

How amoeba obtains its food? |
|
Answer» Amoeba is obtain its food by the process of phagocytosis. Its by psedopodia that the capture their food they stretch their body to capture the food. Amoeba has not fixed shape and they can stretch thei body in any direction. by the process of endocytosis.it ingulf the food particles with the help of psedopodio and then from vacoule around it Ameoba capture the food by forming False feet or psuedopodia to surround the food it captute the food in sac like structure called food vacuole and digestion process complete in food vacuole and excreta remove through special organ Amoeba obtains its food by the process of endocytosis . It engulfs the food particles whe the help oh pseudopodioa and then form a vacuole around it. When the particles is completely trapped the amoeba secratez digestive enzyms that digest the food thus the amoeba obtains food |

Define laws of inertia |
|
Answer» Law of inertia is also known as Newton\'s 1st law of motion bcoz it was given by Issac Newton. According to this law,an object in motion will continue to be in motion and an output bject in rest will continue to be in rest unless no external forces is applied on it. Law of inertia states that : an object will continue to be in the state of rest or in a state of motion, unit and unless an external force acts on it.Law of inertia which is also known as Newton’s first law of motion. |

Why is ice at 273 Kelvin more effective in cooling than water at the same temperature |
|
Answer» Sorry i did not read que clearly Ice Ice at 273 K will absorb heat energy or latent heat from the medium to overcome the fusion to become water. Hence the cooling effect of ice is more than the water at same temperature because water does not absorb this extra heat from the medium. |

What are the difference between the mass of an object and it\'s weight? |
| Answer» \tMassWeightMass can never be zero.Weight can be zero. As in space if no gravity acts upon an object, its weight becomes zero.Mass is a scalar quantity. It has magnitude.Weight is a vector quantity. It has magnitude and is directed toward the center of the Earth or other gravity well.Mass is commonly measured in kilograms and grams.Weight is commonly measured in Newtons.Mass doesn’t change according to location.Weight varies according to location.The mass may be measured using an ordinary balance.Weight is measured using a spring balance.\t | |

Uniform &Non uniform velocity |
| Answer» Uniform velocity: An object with uniform velocity covers equal distance\xa0in equal intervals of time in a specified direction. For\xa0e.g.\xa0an object moving with speed of 40 km/hr\xa0towards west has uniform velocity.Non-uniform velocity: When an object covers unequal distances in equal intervals of time in a specified direction, or if the direction of motion changes, it is said to be moving with a non-uniform or variable velocity. For e.g.\xa0revolving fan at a constant speed has variable velocity as direction of blades of fan is continuously changing. | |

Definr collenchyma and parenchyma tissue |
| Answer» \tParenchymaCollenchyma1. Parenchyma consists of relatively unspecialized cells with thin cell walls.1. Cells of collenchyma have irregular thickening at the corners. Their thick cell walls are composed of cellulose and pectin.2. They are usually loosely packed; intercellular spaces are present.2. They are compactly arranged; intercellular spaces are small.3. Parenchyma provides support to the plant and also stores food.3. It provides flexibility to the parts of a plant; allows easy bending of leaves and stem without breaking. It also provides mechanical support and structure to the plant.\t | |

What are the laws of motion |
| Answer» Newton gave three laws of motion that describe the motion of bodies. These laws are known as Newton\'s Laws of motion.The first law of motion is stated as: An object remains in a state of rest or of uniform motion in a straight line unless compelled to change that state by an applied force.The second law of motion states that: the rate of change of momentum of an object is proportional to the applied unbalanced force in the direction of forceNewton\'s third law of motion states that: Whenever a body exerts a force on another body, the second body exerts an equal and opposite force on the first body | |
