If displacement of a particle is equal to zero then its distance is equal to |
| Answer» If a body starts from some point, say A, goes in a circle and comes back to point A, then the displacement as defined will be zero. Because the initial and final points will be same and there will be zero distance between them. But in the same case distance will not be zero and will be given by the length of actual path traveled by body.Hence, displacement can be zero, even if distance covered is non-zero. | |

| 9656. |
What is budding? |
| Answer» Budding is an asexual mode of reproducing\xa0new organisms. In this\xa0process, a new organism is\xa0developed from a small part of the parent’s body. A bud which is formed detaches to develop into a new organism. The newly developed organism remains attached as it grows further. It is separated from the parent organism when it gets matured by leaving scar tissues behind. As this is an asexual reproduction, the newly developed organism is a replica of the parent and is genetically identical. | |

3 Examples of fertilizers |
|
Answer» manure, worm castings, compost, bone meal A fertiliser is a chemical compound that is given to a plant to promote growth. Fertilisers usually provide the three major plant nutrients (nitrogen, phosphorus and potassium). Fertilisers are in general applied to the soil so that the nutrients are absorbed by plants through their roots. Examples: potassium chloride (KCL), potassium nitrate (KNO3) , ammonium phosphate (NH4)3PO4, calcium superphosphate Ca(H2PO4)2 ammonium nitrate (NH4NO3), urea CO(NH2)2 |

Why lysosome is called as "suicide bag" ? |
|
Answer» 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 It engulf waste materials or disposals of cell and after full of ag it burst into the cell that is why lysosome is called.......... |

Define refraction |
|
Answer» The change of direction of light because of change of medium is known as Refraction or Refraction of Light. The ray of light changes its direction or phenomenon of refraction takes place because of difference in speed in different media. The light travels at faster speed in rare medium and at slower speed in denser medium. The nature of media is taken as relative. For example air is a rarer medium than water or glass. Refraction is the bending of light from one medium to another medium |

Obtain a relation between g and G |
| Answer» G stands for Newton\'s universal gravitational constant, whereas g stands for the acceleration due to gravity at a certain point.G =\xa06.67300 × 10-11\xa0N.m2.kg-2.\xa0G is a constant throughout space and time.g = 9.8 m.s-2. g is a variable quantity.G is a scalar quantity whereas g is a vector qualtity.\xa0\xa0(According to Newton\'s law of universal gravitation the force of attraction between two bodies is given by F = GMm/r2, where the symbols stand for their usual well known meanings. Also the weight of a body of mass m is F = mg.So mg =\xa0GMm/r2,\xa0or g = GM/r2g is a constant at a given location, which depends upon M and r.) | |

Why cell is called structral and functional unit of life |
|
Answer» Every organism on earth is made up of microscopic organisms called cells. So it is a basic structural and functional unit of life . Many cells form tissue and tissue form organs and organs form organ system which forms an organism so cells are called so.Hope this helped you. Thank you Body of all organisms consists of one or many cells.Therefore,cell is called the structural unit of life .All processes associated with life such as respiration,digestion,excreation,etc,..are performed by cell.So,cell is also called as functional unit of life.. Why cell is called structral and fuctional unit of life |

| Answer» \t\xa0ChordatesNon-ChordatesNotochordPresence of cord or notochord.Absence of cord or notochord.LimbsLimbs are two pairs.Limbs may be more than two pairs.HeartHeart is ventral with hemoglobin, RBC and limbs.\xa0Heart is in a dorsal or lateral position with limbs.ExamplesFrog, fish, bird, reptiles, amphibians and mammals.Cockroach, earthworms, flatworms, jellyfish, sponges, insects, water bears, and other arthropods, annelids and protozoans.Post **** tailThey have post **** tail associated with them.\xa0No post **** tail is present in non-chordates.Circulatory SystemChordates have a closed circulatory system.Usually open circulation of blood takes place in non-chordates.Nerve CordDorsal, hollow and single nerve cord is present in chordates. The nerve cord is without ganglia.Ventral, solid and double nerve cord is present. The nerve cord of non-chordates have ganglia.Gill slitsPharyngeal gill slits are present.Pharyngeal gill slits are absent.RespirationRespiration occurs through the gills or lungs in chordates.Respiration occurs through trachea, gills or body surface in non-chordates.Body fluidHemoglobin is present in chordates.Hemoglobin is absent, instead, hemolymph is present which is analogous to bloods in the vertebrates.Germ layerTalking about the germ layer, chordates are triploblastic.Talking about the germ layer of non-chordates, they can be diploblastic, triploblastic or neither.\xa0SymmetryThese animals are bilaterally symmetric.These animals can be bilateral, bi-radial, asymmetrical or radial.CoelomatesThey are true coelomates.They can either be true coelomates, acoelomates or pseudocoelomates.ExoskeletonExoskeleton is present in some of the chordates, for example, tortoises.Exoskeleton is present in all non-chordates.EndoskeletonEndoskeleton is present in chordates.Endoskeleton is absent in non-chordates.RegenerationChordates have poor regeneration.Non-chordates have good regeneration, mostly.****The **** of these animals is differentiated and opens before the last segment.**** in these animals is usually absent and if present, it opens on the last segment.BrainThe brain of chordates is present, and located dorsal to the pharynx in head.Brain is not as complex as that of chordates if present in some of the animals.OrganizationThey have a body with an organ system.Their body organization is protoplasmic to the organ system.\t | |
