    Hints and explainations:-



    1.   Hot-spots are areas of megadiversity which are  also the  most threatened

    ones.  The number of hot-spots is 25, of which two  are present

    in India namely Western Ghats and North-East Himalayas.

    In India, Indo-Gangetic Plain, Eastern Ghats  and Aravali Hills are not considered as  hot-spot of



    2.   Dachigam National Park located near Dal Lake in Jammu and Kashmir is known for  conservation of endangered Hangul or Kashmir stag.






    1. Ethnology:- study of ethnic people

    Eugenics: meaning “well born” or “good birth” relates to measures to select/change/improve/discard a genotype/phenotype of an offspring in order to improve the line.

    Euthenics: Measures to improve the environment in order to improve health, appearance, behavior, or well-being of society.

    Euphenics: Measures to improve the individual or phenotype (the body) by biological or medical means.

    1. Gene flow does occur between the populations of a species


    1. The members of same species can reproduce freely with each other.


    1. Foetal Hb has different composition than that of an adult Hb


    1. K+ ions enter guard cells. As a result water move in due to osmotic effect that makes guard cell become turgid and hence stomata open.


    1. In plants, Boron is required for calcium uptake, carbohydrate metabolism and germination of pollen tube.


    1. A layer of sterile cells is absent in algae


    1. Living fosiils are extinct fossil species.


    1. Xylum in cycas mainly consists of tracheids
    2. homologous organs are similar in structure but different in function


    1. During cleavage, nucleo-cytoplasmic ratio increases, size of blastomeres/cells decreases, more oxygen consumption and mitotic divisions take place.


    1. Archenteron is gut of embryo


    50 Palaeontology is study of fossils.


    1. Schizogony takes place in man


    55 ponds and puddles are breeding grounds for mosquito. Mosquito is an intermediate host ofPlasmodium .


    1. bacteria and blue-green algae are prokaryotes that do not have membrane bound cell organelles


    1. Euchromatic regions replicate first


    86 parietal cells produce HCl
