Prophase is the first stage of mitosis. In prophase, chromosomes condense and become visible, spindle fibers emerge from the centrosomes, nuclear envelope breaks down, nucleolus disappears

Metaphase is the second step in mitosis. In metaphase the mitotic spindle is fully developed, centrosomes are at opposite poles of the cell, chromosomes are lined up at the metaphase plate, each sister chromatid is attached to a spindle fiber originating from opposite poles

Anaphase is the third step in mitosis. In anaphase, cohesin proteins binding the sister chromatids together break down
sister chromatids (now called chromosomes) are pulled toward opposite poles
non-kinetochore spindle fibers lengthen, elongating the cell

Telophase is the fourth step in mitosis. In telophase, chromosomes arrive at opposite poles and begin to decondense, nuclear envelope material surrounds each set of chromosomes, the mitotic spindle breaks down

Cytokinesis is the fifth and final step of mitosis. In cytokinesis, Animal cells: a cleavage furrow separates the daughter cells
Plant cells: a cell plate separates the daughter cells

Answer:

Prophase is the first phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells.

Metaphase is a stage in the cell cycle where all the genetic material is condensing into chromosomes.

Anaphase is the stage of mitosis and meiosis in which the chromosomes move toward the poles of the spindle.

Telophase is the final stage of mitosis and of the second division of meiosis in which the spindle disappears and the nucleus reforms around each set of chromosomes.

Cytokinesis is the division of cells after either mitosis or meiosis I and II.

In immediate hypersensitivity, the initial exposure to an allergen usually does not produce any symptoms. the symptoms, such as

stepladder [879]

During the initial exposure to the allergen, contact is made with B cells, these B cells differentiate and produce IgE antibody. The IgE antibodies which works against the allergens are released into the blood stream where they binds to Fc receptors which are located on mast cells and basophils. Now, the mast cells has become sensitized and they will wait patiently for the second exposure. When contact with the allergen is made the second time, the allergen becomes attached to the IgE present on the mast cells and this result in degranulation which trigger a lot of allergic responses.
