Page 3 - The roots of a plant have root hair cells that absorb water from the soil. The diagram below shows two
different kinds of roots. The concentration of the solution inside the cell is higher than the concentration
the solution in the soil.
a) Explain why water moves from the soil into the root hair cell.
tap root system

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".

the answer is 0.8m.
