Answer : In the first reaction, 'A' is the atomic mass of barium = 143

In the second reaction, 'B' is the atomic mass of barium = 145 and 'C' is the atomic number of barium = 56

Explanation :

Nuclear fusion : It is a process which involves the conversion of two small nuclei to form a heavy nuclei along with release of energy.

Nuclear fission : It is a process which involves the conversion of a heavier nuclei into two or more small and stable nuclei along with the release of energy.

The complete nuclear fission reaction are,

(1)

In this reaction, 'A' is the atomic mass of barium = 143

(2)

In this reaction, 'B' is the atomic mass of barium = 145 and 'C' is the atomic number of barium = 56

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.

lysosome is this part of the cell is surrounded by a very thick outer membrane to protect the rest of the cell from its strong enzymes.
