    Sodium is kept in kerosene while phosphorus is store in water bacause sodium reacts with water and phosphorus do not react with water

    0Thank You

    Nithya Vijay 5 years, 10 months ago

    Sodium reacts vigorously with oxygen and water at room temperature and gives out more amount of heat, the kerosene layer acts as a shield in between the metal and the atmospheric oxygen. Phosphorous also very reactive and burns in air but does not form water or react with water, hence it is stored under water

    1. When a person reaches puberty, he or she becomes an adolescent. Adolescence continues up to the age of 18 or 19 years. During adolescence, a boy or a girl reaches mental, intellectual and emotional maturity. Adolescence is a period of change in a person's way of thinking. Adolescents are more independent than before and are also self conscious. Intellectual development takes place and they tend to spend considerable time thinking. In fact, it is often the time in one's life when the brain has the greatest capacity for learning. Sometimes, an adolescent may feel insecure while trying to adjust to the changes in the body and mind. The changes which occur in the body of boys and girls may cause emotional swings which show intense feelings like joy, anger, boredom, worries or sadness which are not based on reasoning or knowledge. These changes are a natural part of growing up process.

    Binary fission is a method of asexual reproduction. In this method the body of the animal divides into two halves. The nucleus divides into two, followed by the division of the whole body. It gives rise to two individuals.  Amoeba reproduce by binary fission.

    Budding is a form of asexual reproduction where a bud or outgrowth from the end or side of the parent organism emerges and develops into a new organism. This is seen in fungi, hydra as well as in plants. Usually, the protrusion stays attached to the primary organism for a while, before becoming free. The new organism is naturally genetically identical to the parent. When yeast buds, one cell becomes two cells. When a sponge buds, a part of the parent sponge falls off and starts to grow into a new sponge.

    Budding and binary fission

    0Thank You

    Yogita Ingle 5 years, 10 months ago

    1) Fission

    Fission means division. During asexual reproduction, the parent cell divides into two or more cells. Unicellular organisms show different patterns of cell division according to their cell structure. For example, an amoeba can divide itself into two at any plane but the division in euglena is longitudinal.

    2) Fragmentation

    Fragmentation is another mode of asexual reproduction. Multi-cellular organisms like planaria, spirogyra, etc. reproduce by fragmentation. The parent body divides into two or more fragments. Later, each fragment develops into a new individual.

    3) Regeneration

    When a lizard loses its tail, it grows a new one. This is known as regeneration. In many organisms, there are specialized cells, which can differentiate and grow into a new organism. Organisms like hydra and planaria also show regeneration. In these organisms, when the cell divides into numerous pieces, each piece proliferates and differentiates to regenerate new organisms.
