Specific ordinary differential equations and the ODE solver are briefly
presented together with examples for bio-systems that can be represented by differential
equations, one or a set. The solutions are demonstrated for the bio-molecular reaction,
the predator-prey model, the drug dissolution, the batch reactor, etc. The questions and
life-science problems together with answers to some of them are given in conclusion.
Keywords: Ordinary differential equations, ODE solvers, solution steps, biomolecular
reaction, predator-prey, drug dissolution, batch reactor.
