How does a cell in your spleen know how to express spleen genes

During growth and development of the embryo, the multipotent cells move to particular regions of the embryo and begin to differentiate - beginning in the gastrulation stage. The cells vary in the silencing of particular genes so that they produce only the appropriate proteins for the specific function of the organs that they develop into. Silencing means particular areas of the genetic material are inaccessible to polymerase enzymes because they are locked up into nucleosomes by histone complexes. Therefore the genes that are turned on in skins cells may differ slightly with those of the spleen cells.

one of the spleen's major jobs is filter the blood.

Explanation:

One of the spleen’s main jobs is to filter your blood. It affects the number of red blood cells that carry oxygen throughout your body, and the number of platelets, which are cells that help your blood to clot. It does this by breaking down and removing cells that are abnormal, old, or damaged.  

The spleen also stores red blood cells, platelets, and infection-fighting white blood cells.  

The spleen plays an important role in your immune system response. When it detects bacteria, viruses, or other germs in your blood, it produces white blood cells, called lymphocytes, to fight off these infections.

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
