    In humans, implantation is the stage of pregnancy at which the embryo adheres to the wall of the uterus. At this stage of prenatal development, the conceptus is called a blastocyst. It is by this adhesion that the embryo receives oxygen and nutrients from the mother to be able to grow.  Implantation is a process in which a developing embryo, moving as a blastocyst through a uterus, makes contact with the uterine wall and remains attached to it until birth. If the zygote implants in any area besides the uterus, the result is an ectopic pregnancy.

    The 1848 revolution of the liberals refers to the various national movements pioneered by educated middle classes alongside the revolts of the poor, unemployed and starving peasants and workers in Europe. While in countries like France, food shortages and widespread unemployment during 1848 led to popular uprisings, in other parts of Europe (such as Germany, Italy, Poland, and the Austro-Hungarian Empire), men and women of the liberal middle classes came together to voice their demands for the creation of nation-states based on parliamentary principles. The political, social and economic ideas supported by the liberals were: Politically, they demanded constitutionalism with national unification, nation-state with a written constitution and parliamentary administration. Socially, they wanted to rid society of its class-based partialities and birthrights. Serfdom and bonded labor had to be abolished. Economically they demanded freedom of markets and right to property. The abolition of state-imposed restrictions on the movements of goods and capital.

    The prevention of pregnancy in women (by preventing fertilisation) is called contraception. There are four methods of contraception:

    1. Barrier method: In barrier method of contraception, the physical devices such as condoms are used by males and females.
    2. Chemical method: In chemical methods of preventing pregnancy, the females use two types of pills – oral pills and vaginal pills.
    3. Intra-Uterine Contraceptive Devices – The use of intra-uterine contraceptive devices like Copper-T is very effective in preventing pregnancy.  A Copper-T is placed inside the uterus by a doctor to prevent unwanted pregnancies.
    4. Surgical method: These methods are available for males as well as for females. Vasectomy is done in males and tubectomy is done in females.
    1. Vasectomy - In males, a small portion of the sperm duct (Vasdeferens) is removed by surgical operation and both the cut ends are ligated properly. This prevents the sperms from coming out.
    2.  Tubectomy - In females, a small portion of the oviducts is removed by surgical operation and the cut ends are ligated. This prevents the ovum from entering into the oviducts.

    Asexual Reproduction is extremely useful as a mean of rapid multiplication. It is common in lower plants and animals. MODES OF ASEXUAL REPRODUCTION : the mode depends on the body design of the organism. 1. FISSION:The parent cell divides/splits into two daughter cell-Binary Fission; splits into many cells-multiple Fission.   FISSION Binary Fission The parents cell divides into two equal halves Equal halves (daughter cells) E.g. Amoeba follows transverse binary fission,i.e. fissin in any plane. ->Leishmania has a whip-like structure at one end and binary fission occurs in a definite orientation. Multiple Fission The parent cell divides into many daughter cell simultaneously. Eg. Plasmodium  the process where nucleus lengthens is NUCLEOKINESIS and where the cytoplasm lenghthens is CYTOKINESIS. 2. BUDDING: A bud develops as an outgrowth on parent body due to repeated cell division at a specific site. These buds detach from the parent body when they mature. E.g. Hydra, yeast.  3. SPORE FORMATION : Spores which are present in sporangia, are small, bulb like structure which are covered by thick walls that protect them until they come in contact with suitable condition. Under favourable conditions, they germinate and produce new Rhizopus indiviual.  4. FRAGMENTATION : It takes place in multicellular organism with simple body organisation. It is the accidental process when the brokenpieces of an organism (fragments) grows into a complete organism.  5. REGENERATION : When the simple animals like Hydra ,Planaria develop a new individual from their broken older part it is known as regeneration. It is carried out by specialised cells which divide and differentiate to form the complete individual. These cells multiply and from this mass of cells other parts are generated. Regeneration follows an organised sequence referred to as DEVELOPMENT.  Vegetative Propagation A mode of reproduction in which reproduction takes place from the vegetative parts like the stem, root, leaves. Methods of Vegetative Propagation Natural 1. By Roots : E.g. adventitious roots of Dahlias 2. By Stems : E.g. Potato (tuber), ginger (rhizome) 3. By Leaves :E.g. leaves of bryophyllum bear adventitious buds (in the notches of leaf margin) which develop into new plants. Artificial 1. Grafting : E.g. Mango. 2. Cutting : E.g. Rose 3. Layering : E.g. Jasmine 4. Tissue adture : E.g. Orchids, Ornamental Plants. Benefits of Vegetative Propagation 1. Plants can bear flowers, fruits earlier than those produced from seeds. 2. Growing plants like Banana, orange, rose, jasmine that have lost the capacity to produce seeds. 3. Genetical similarity is maintained in the plants. 4. Helps in growing seedless fruits. 5. Cheaper and easier method of growing plants.

    Patriotism means intense love and support to ones own country. Patriotism and nationalism is one and the same thing for both believe in putting national interests above other international considerations. Patriotism is one of the strongest human sentiments. It is expected from every citizen of a country that he or she would cherish a deep and abiding love and concern for the country, yet there can be found many traitors and spurious patriots.
