Which of the following correctly explains the steps pictured below? an image depicting three stages of meiosis. the first shows two cells with chromosomes still paired as sister chromatids and spindle fibers beginning to form. the second pair of cells shows sister chromatid pairs lined up in the middle of the cell with spindle fibers attached to the centromeres of each pair. the third pair of cells shows the centromeres separating and individual chromosomes moving along the spindle fibers to opposite ends of the cell. prophase ii, metaphase ii, anaphase ii prophase ii, anaphase ii, telophase ii prophase i, prophase ii, metaphase i prophase i, metaphase i, anaphase i

The stages of the meiosis process described above are as follows: PROPHASE II, METAPHASE II AND ANAPHASE II. 
Meiosis is a form of cell division, which results in the formation of four daughter cells that possess half the number of the chromosomes in the parent cells. The process is divided into eight basic steps, which are: prophase l, metaphase l, anaphase l, telophase 1 and cytokinesis, prophase ll, metaphase ll, anaphase ll and telophase ll and cytokinesis.
The following happened in the three stages mentioned in the question above:
1. Prophase ll: A new spindle is formed around the chromosomes.
2. Metaphase ll: The chromosomes lines up at the equator.
3. Anaphase ll: The centromere divides and the chromatids move to the opposite pole of the cell.

answer: - b cells

explanation: -

there are many types of white blood cells present in our body. one such class of white blood cells are the lymphocytes. the b cells belong to the lymphocyte class of wbcs. the b cells perform their action against the pathogen by producing specialised proteins called as antibodies. these antibodies are produced as and when the b cells encounter pathogens in response to the antigens present on the surface of the pathogen. these antibodies bind to the antigens present on the pathogen and then, target them for destruction by other cells of the immune system.

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.
