Answer:
Anthocerophyta, Bryophyta, Hepatophyta.
Explanation:
Non vascular plants are defined as the plants which contains phloem, and xylem without the vascular system. They are containing simpler tissues which are specialized for internal transport of water.
They include bryophyta, hornworts (anthocerophyta), liverworts (hepatophyta) mosses, and some algae. Non vascular plants reproduce with the help of spores, and do not produce fruit, and flowers.
Answer:
Bio carbonate ions
Explanation:
The pancreas secrets an aqueous mixture ( water, digestive enzymes and bicarbonate ions) during digestion of food substances from the stomach into the duodenum to begin the process of absorption and assimilation.
The pancreatic duct are lined with duct cells. These are cells which secretes HCO3- ,into the aqueous mixture. This ion is basic. Therefore it neutralizes the acidity of the of the chyme to released from the stomach to enable the pancreatic enzyme to work.
The bicarbonate ions also prevent the walls of the pancreases from getting burnt by the effect if the acidity of the chyme.
