1. identify ways the system can be divided into two or more subsystems.
2. describe at least two ways these subsystems interact through the inputs and outputs of each subsystem.

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".

1 is the answer to this problem

the objects have the same charge.
