35. During the development of a Bioresorbable material for use as a scaffold in tissue regeneration applications, the researchers at the Medtronic Corporation have been able to create two sample structures - Sample A material having crystal grains which are 11μm in diameter, and Sample B having crystal grains which are 7μm in diameter. Based upon this information, which is likely to have a slower rate of dissolution and resorption when placed in a body? (3 points)
a) Sample A
b) Sample B
c) Both are likely to have equivalent rates.
