explain the terms analogous and homologous organ |
|
Answer» Analogy:It refers to the similarity in function of two different organisms due to convergent evolution and not common ancestry.Analogy in Animals: Analogous organs are the opposite of homologous organs, which have similar functions but different origins. An example of an analogous trait would be the wings of insects, bats and birds that evolved independently in each lineage separately after diverging from an ancestor without wings.The wings of insects originate from the inner or outer surface of the insect’s body. Feathers of birds originate from their forelimbs, and the wings of bats originate from both the fore limb and the membranous skin of the abdomen.Homology: Homology refers to the traits inherited by two different organisms from a common ancestry. Homology in Animals: Organs such as bat\'s wing, wings of birds, seal’s flipper, forelimb of a horse, and human arm have a common underlying anatomy that was present in their last common ancestors therefore their forelimbs are homologous organs.We can observe that though the shape and the size of the bones are not similar, there is a similarity in their structure that is, they have the same set of bones humerus, radius, ulna, carpals, metacarpals and phalanges. Man uses his hands to grasp and perform tasks, whales use their flippers for swimming, bats and birds use their wings for flight and horses use their forelimbs for running. Analogous are different in basic structure and have same functions whereas homolgous organs have same structure but different functions .. Examples of analogous wing of bat and bird examples of homologous organs are lizard,frog, etc kkkkk ☺????? |

What happen when blue colour of CuSO4.5H2O is heated |
| Answer» The blue colour is due to the water of crystallization (CuSO4.5H2O). When this is removed by heating, basic copper sulphate is left (CuSO4.H2O) and this can be further broken to simple CuSO4. It is essential you realize the water is not there as free liquid, but as a molecule in its own right and it is bound to the copper atom.In the case of all transition metals, the water of hydration is linked to the d (or higher) orbitals and these distort slightly, thereby causing a band energy shift that is characterized by the colour. In the case of copper this shift is in the 600-900 nm region and this is where the blue-green colours occur. | |

Explain functional group |
| Answer» Functional groups in organic chemistry are those which are responsible for the changes in the physical and chemical properties of an organic compound. There are various functional groups in organic chemistry.An atom or group of atoms which show a characteristic unique reactivity when treated with some reagents and also which impart some unique chemical as well as physical properties to the primary molecule is defined as a functional group.Some of the examples of functional groups is carboxylic acid (RCOO-) and ester (R-COO-R). This comprises of an acyl group (RCO-) and an alkoxy group (-OR’). | |

Why saturated are less reactive then unsaturated |
| Answer» The saturated designation means the carbon atom in compound have as many hydrogen are allow in them ...take the simplest hydrocorbon ,mithan :-it has one carbon and four hydrogen there is no atom remains to react with other elements ...where as unsaturated hydrocarbon makes double or triple bond and it has room to bond with others element ..that\'s why unsaturated is more reactive than saturated hydrocarbon | |

Defination of functional groups |
|
Answer» Functional group defines the structure of a family of compound and determines its properties Functional groups are specific groups of atoms or bonds within molecules that r responsible for the characteristic chemical reaction of the molecule Functional groups are specific groups (moieties) of atoms or bonds within molecules that are responsible for the characteristic chemical reactions of those molecules. The same functional group will undergo the same or similar chemical reactions regardless of the size of the molecule it is a part of. |

What is difference between alkaline and alkali metal |
| Answer» The bases that can dissolve in water are alkalis, while those that do not dissolve in water are not alkali. That is, except for those that can dissolve in water, all foundations are not alkaline. We may also conclude that alkali is a fundamental\xa0hydroxide\xa0that dissolves in water, converting blue into red litmus.There are low electron affinities and low electronegativity on alkaline earths. As with alkali metals, the properties depend on how simple it is to lose electrons. In the outer shell, the alkaline earth has two electrons. They have atomic radii that are smaller than alkali metals. | |

What were the limitations of newlands law of octaves |
| Answer» Limitations :-\tThe law of octaves was found to be applicable only upto calcium. It was not applicable to elements of higher atomic masses.\xa0\tPosition of hydrogen along with fluorine and chlorine was not justified on the basis of chemical properties.\xa0\tNewlands placed two elements in the same slot to fit elements in the table. He also placed some unlike elements under the same slot.\tFor example, cobalt and nickel are placed in the same slot and in the column of fluorine, chlorine and bromine. But cobalt and nickel have properties quite different from fluorine, chlorine and bromine. Similarly, iron which has resemblances with cobalt and nickel in its properties has been placed for away from these elements.\tThus, it was realized that Newlands’ law of octaves worked well only with lighter elements. Therefore, this classification was rejected. | |
