When does the cell cycle start? when does it end?

Solution:

The cell cycle is continuous because our cells are constantly dying and making new cells.  

It is is made up of:

1 phase: things inside of the cell begin to grow.  

Middle phase: DNA and only the DNA divides  

Last phase: All other organelles divide  

Then finally comes Mitosis which has:  

Prophase: chromosomes condense, centrioles move to opposite poles, nuclear membrane dissolves, spindle begins to form  

Prometaphase: smindles attach to chromosomes (but they are not aligned)  

Metaphase: chromosomes are on the metaphase plate. They are lined in the center.  

Anaphase: spindles pull the sister chromatids apart  

Telophase: everything that happened in phrophase..but the OPPOSITE!  

Thus we get finally is Cytokinisis where the cell divides

the answer is c. it will give up it's valence electron to the other atom.

can you make it bigger i can't see it
