Something is alive if it has cellular organization (building blocks that perform actions necessary to survival), Order (hierarchy of molecular structures), Sensitivity (reacting to the outside world), Growth, development and reproduction (the ability to grow or increase one’s self in order to become more adept), Making use of acquired and produced energy, Adaption (encounters with other things or creatures and as a result able to survive more naturally in its environment), Homeostasis (having a constant and balanced inside, different from your surrounding world). 2) An Isotope is essentially a certain element that has a different amount of protons than it normally would.
