Why are lysosome known as sucidal bag? |
|
Answer» Therefore they are called suicidal bags of the cell When the cell becomes dead or when it does not work properly then then the lysosomes brust out and the digestive enzymes inside the lysosomes surround the cell and digest it\'s own cell leaving space for another cell to develop. Lysosomes are cellular organelles that contain digestive enzymes that break down waste materials, foreign material and cellular debris. Lysosomes are capable of digesting nucleic acid, polysaccharides, fats, and proteins. Along with them lysosomes also digest or damage its own cells by its own enzymes, which lead to cell death. This process is called as autolysis. Hence lysosomes are also called as suicide bags . |

what r canal rays |
|
Answer» Canal rays are also called protons and they are positively charge radiations In simple language the rays which travels against cathode through anode are canal rays. The beam of rays which travel in a direction away from anode towards cathode when a gas taken in a discharge tube is subjected to the action of high voltage under low pressure are known as canal rays. It is also called anode rays. It was discovered by E. Goldstein in 1886. |

Expression for potential energy |
|
Answer» If we raise a body of mass"m"to a height "h" and during this a force of acceleration due to gravity is acting in opposite direction of the motion of the body..Now we know that work done=force*distance........(1)And we also know that face=Mass*acceleration =m*g...........(2)And here perpendicular distance=h..........…..............,....(3)From (1) ,(2) and (3):Work done=force*distance =m*g*hAnd we also know that work done=energy consumed or energy used up.And we also know that energy consumed by a body=energy gained by another body. ,(if work is done by first body on another second body)Therefore, energy=m*g*h..Here the body is raised therefore here energy will be gravitational potential energy...So. Potential energy=m*g*hNote: g=acceleration due to gravity . While G=gravitational constant M×G×HWhere M=massG=gravitation forceH=height |

Differentiate between simple distilation and fractional distilation. |
| Answer» Simple distillation\xa0Simple distillation is used when the boiling points of chemicals in a mixture having large differences (more than 25°C).No fractionating columns used as the difference in the boiling point of mixture is large.\xa0E.g. Process used in separating kerosene and petrolFractional distillationFractional distillation is used when the boiling points of chemicals in a mixture are close to each-other, usually within 77°F (25°C).Fractionating columns used to separate the mixtures.E.g. Process used in the separation of Crude Oil into useful fractions. | |

Define reverberation |
| Answer» Many multiple echoes of a sound can be produced are called as reverberations. Reverberation\xa0is the phenomenon of overlapping of sound caused by multiple reflections. Reverberation\xa0causes the overlapping of several reflected waves. If the time gap between the reflected waves is so short that these cannot be distinguished. So we hear multiple noisy sounds. Example:\xa0reverberation of sound occurs in small cave almost the gap between the walls is approximately 17 m. | |

What is archimedies principle |
|
Answer» It states that when a body is immersed fully or partially in a fluid, it experiences an upward force that is equal to the weight of the fluid displaced by it. Archimedes\' principle states that the buoyant (upthrust) force exerted on a body submerged in a fluid, whether fully or partially, is equal to the weight of the fluid that the body displaces.\xa0One of the most useful discoveries to mankind in the field of physics is Archimedes’ principle. Based on this principle, a device called a hydrometer was developed which helps in measuring the density of liquids with ease.\xa0Archimedes’ principle states that “When a body is immersed completely or partially in a fluid, it experiences an upward force that is equal to the weight of the fluid displaced by the body.”According to the principle, a solid that floats or is immersed in a liquid appears to lose its weight which is equal to the weight of the liquid displaced by the solid. Whether a given solid drowns or not in a given liquid depends on the density of the solid in comparison with that of the liquid.For an easy approach, we consider the relative density of the substance, which is the ratio of the density of the substance to the density of water, which obviously has no units but a mere number.\xa0If the relative density of the given solid is greater than that of the given liquid, it drowns in the liquid as there is a net downward force on the solid after it gets completely immersed in the liquid. If the relative density of the liquid and that of the solid are equal, then the solid just floats or drowns.\xa0This implies that the solid immerses in the given liquid and stays suspended at the kept position. If the relative density of the given solid is lesser than that of the given liquid, it floats in the liquid.\xa0This happens due to the up thrust or buoyant force of the liquid acting on the solid. The relative density of a floating solid in a given liquid gives the measure of the percentage of the solid that lies below the surface of the liquid.The “relative density” or “specific gravity” of a substance is defined as the ratio of its density to the density of water at 4 degrees Celsius.\xa0Relative density =\xa0Density of substance\xa0Density of water at 4\xa0℃\xa0This can be expressed in many ways. If the numerator and the denominator are both multiplied by “volume”, then we get the expression relative density is equal to the ratio of “mass of the substance” to “mass of water of the same volume.”Relative density = Mass of substanceMass of water of same volume\xa0Again, when the numerator and the denominator are both multiplied by acceleration due to gravity “g”, the expression becomes:Relative density =\xa0Weight of substanceWeight of water of same volume\xa0When the substance is immersed in water, it displaces water of volume equal to its own volume. According to Archimedes’ principle, the apparent loss of weight of a body immersed in water is equal to the weight of the water displaced. Therefore:Relative density =\xa0Weight of substance\xa0Apparent loss of weight when immersed in water\xa0This expression can be used to find the relative density of a solid body. In order to find the relative density of a liquid, a solid body is taken and its weight is found in air. Then, the weight of the same body is found when it is completely immersed in the liquid whose relative density is to be found. Finally, the weight of the body is found by immersing it completely in water. The relative density of the liquid can be found using the expression:\xa0Relative density = Loss of weight of a solid body when immersed in liquid\xa0Loss of weight of the same body when immersed in water\tThe relative density of a substance is the ratio of density of the substance to the density of water.\tRelative density should be calculated using the same system of units for the substance as well as water.\tA hydrometer uses Archimedes’ principle to determine the density of any liquid.\tArchimedes’ principle is also used in designing ships and submarines.

What is the difference between symptoms and signs??? |
| Answer» A symptom is a manifestation of disease apparent to the patient himself, while a sign is a manifestation of disease that the physician perceives.
