\'Evolution and classification are interlinked\'. Justify. |
|
Answer» Evolution is a slow change in the body design and other characteristics of an organism over a long period of period that ultimately cause the formation of new speciation from pre-exiting species. Different forms of organisms/ life have evolved during the course of evolution.Classification deals with grouping of these organisms into groups and subgroups based on their similarities and differences. The more characteristics any two species have in common more closely they are related/ will have a more recent ancestor and vice versa.Thus, classification helps tracing the evolutionary relationships between the two organisms hence classification and evolution are interlinked. Evolution is a slow change in the body design and other characteristics of an organism over a long period of period that ultimately cause the formation of new speciation from pre-exiting species. Different forms of organisms/ life have evolved during the course of evolution.Evolution is a slow change in the body design and other characteristics of an organism over a long period of period that ultimately cause the formation of new speciation from pre-exiting species. Different forms of organisms/ life have evolved during the course of evolution. Evolution and classification are interlinked with each other in the following ways:1.classification is most important term to explain evolution2.classification is based on similarities and differences between 2 species or among 2 organisms3.the more characteristics 2 species will have in common, the more closely they are related,and the more closely they are related ,the more recently they will have had common ancestor.4.for example:a brother and sister are closely related. They will have common ancestor in first generation before them,their parents5. A girl and her cousin are also related but less than the girl and her brother. This is because cousins have common ancestors their grandparents in second generation before them,not in the first oneSo,we can say that classification of species is in fact a reflection of their evolutionary relationship |

Why NaCl in aqueous solution is neutral while Na2CO3 is basic ?? |
|
Answer» We know that salts are formed when acids and bases react with each other.Neutral salts are formed when concentrated acids react with concentrated bases and when dilute bases react with dilute bases. But Na2CO3 is formed by the reaction of dilute acid with concentrated base. So it is basic in nature. Bcoz NaCl is formed by a strong acid and strong base so the salt is neutral while NaHCO3 is formed by a weak acid and strong base so the salt is basic in nature .... |

Where is the magnetic field is stronger in a circular loop |
|
Answer» Near the center stronger away from center weak. The two magnetic field lines do not intersect each other because if they do it means at the point of intersect the compass needle is showing two different directions which is not possible. Gaurav tell why don\'t two magnetic lines of force intersect each other We know, when magnetic field is directly proportional to magnetic lines of force . Means if magnetic lines of force are more concentrated at a point respect to another point then that point have more magnetic field with respect to the point which contains less concentrated magnetic lines of force.\xa0In case of circular loop, magnetic lines of force are highly concentrated at centre as shown in figure. so, magnetic field is strong at centre . While in case of circumference , magnetic field is weaker than centre. |
