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.
This type of multicellular exocrine gland has a branched rounded secretory part attached to a single unbranched duct and is found mainly in sebaceous glands. simple branched acinar gland. simple tubular exocrine glands have. a straight tubular secretory portion attached to a single unbranched duct.his type of multicellular exocrine gland has a branched rounded secretory part attached to a single unbranched duct and is found mainly in sebaceous glands. simple branched acinar gland. simple tubular exocrine glands have. a straight tubular secretory portion attached to a single unbranched duct.
