Answers Latest Update
Metabolism - Answer-Growth depends on a large number of chemical reactions
Fueling - Answer-Some Transformation of Energy

vitamins, etc)
Polymerization - Answer-Reactions that make the macromolecules
Increase in Growth - Answer-If a microbe is in an environment that has carbon but
doesn't have nitrogen it might bring carbon in and store it. This does not mean _____ ,
but it might mean an increase in mass. They store it until Nitrogen is available again.
