1 In a solution of potassium hydrogen iodate [KH(IO 3) 2 ] at 0.02 M the activity is 40% lower than the calculated hydrogen ion concentration, resulting in a much higher pH than expected.

Endocrine Glands. Endocrine glands lack ducts-they are often referred to as ductless glands.. Endocrine glands secrete directly into the tissue fluid that surrounds them.The product of endocrine glands are hormones, which they release into the extracellular space.lassification of Glands. Glands are classified as endocrine (internal seceretion) or exocrine (external secretion) depending on where they release their product and unicellular or multicellular based on the number of cells in the gland.
