Biology Key Questions – Lesson #1 1. How many electrons does Mg2+ have? Answer: Mg2+ has 10 electrons. A Magnesium atom has 12 electrons‚ 2 of which are valence electrons. The atom will lose the 2 outermost electrons in order to stabilize its electron shell. The nucleus maintains its 12 protons and becomes a Mg2+ ion. 2. Given that the half-life of the radioisotope carbon-14 is 5730 years‚ how useful do you think this isotope would be for dating bones that are over a million years

Matthew Nims Biology Honors Reflection 2nd nine weeks Period: 2 In this honors portfolio we created models of the cell cycle and used those models to create an animation. The purpose of this is to‚ first‚ memorize the visuals of the cell cycle. The Second is to understand what’s going on in the visuals by creating commentary to describe the changes from stage to stage. The third is to repeat the first and second by critiquing other videos. We used our understanding of mitosis that we
