Nuclear Meltdown: Abstract
A nuclear power plant produces energy from the splitting of atoms from elements such
as uranium and plutonium. This is a relatively new type of energy producer and is more
environmentally safe than non-renewable resources (coal,
7. All enzymes work faster when at a higher temperature because the molecules gain more
energy but if the lactase were to be used at the higher temperature where it works faster the
enzyme would be denatured. Denaturation is a structural change in a prote

the time of day differing in each trial to a light bulb having a slightly different wattage from
another could cause major discrepancies in the results. With t
