When the nucleus of a U-235 atom captures a moving neutron it splits in two (fissions) and releases some energy in the form of heat, also two or three additional neutrons are thrown off. If enough of these expelled neutrons cause the nuclei of other U-235 atoms to split, releasing further neutrons, a fission 'chain reaction' can be achieved. When this happens over and over again, many millions of times, a very large amount of heat is produced from a relatively small amount of uranium.
It is this process, in effect "burning" uranium, which occurs in a nuclear reactor. The heat is used to make steam to produce electricity.
Answer:
The beginning and majority of the time is known as Interphase. Interphase is 80% of the total cycle and is where the cell does most of the work in replicating organelles, chromosomes, and preparing to undergo Mitosis which is the actual splitting process where one cell becomes two. During Interphase there are 3 major steps, G1, S, and the G2 phase.

Because the hole in the window is larger on the outside, Bill concludes that
there was an impact from outside the house with an object such as a stone
He can also infer that the object that went through the glass has a pointed shape whose tip first crossed the glass
Primary producers pump energy into an ecosystem from an environmental source and then the energy is passed from one organism to another
