[Q]: Process:  -Prophase is the first and longest stage of mitosis -In this stage the chromosomes become visible and the centrioles separate and move to opposite poles of the cell -In prophase the chromosomes become visible and the centrioles separate and move to opposite poles of the cell -In metaphase the chromosomes line up across the center of the cell and become connected to the spindle fiber at their centromere -In anaphase the sister chromatids separate into individual chromosomes and are pulled apart -During telophase the chromosomes gather at opposite ends of the cell and lose their distinct rod-like shapes -Two new nuclear membranes then form around each of the two regions of DNA and the spindle fibers disappear.

[Q]: Process:  -Coal is mined out of the ground -Coal is pulverized into fine powder -The coal is mixed with hot air -The coal and hot air are blown into a boiler -The coal and hot air burn over a fire -Highly purified water is pumped through pipes in the boiler -The water turns into steam -The steam presses against turbines -The turbines spin -Electricity is produced.
 Question: What is the effect of less coal is used on less coal is pulverised.?
