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.
Glands that secrete their products directly into tissue fluids or the blood without ducts are called endocrine glands. Those that secrete their products into ducts that open onto internal or external open surfaces are called exocrine glands.f the duct and secretory portions are of uniform diameter, the gland is tubular. If the secretory cells form a dilated sac at the end of the duct, it is acinar, and if the secretory cells extend uniformly from the duct then form a sac, it is called tubuloacinar.
