A polymer is a large molecule made up of smaller molecules called monomers. The process of monomers joining each other to create a polymer is called polymerization. Water plays a role in condensation polymerization. In this reaction a hydrogen from one monomer will connect with the hydroxyl functional group of another monomer. The two join and water is formed. the water breaks off, leaving the remaining functional groups of the  monomers able to be joined together.
Hydrolysis is the opposite reaction where water is added to the polymer. The hydrogen (H) and hydroxide (-OH) react with the functional groups that formed the bond and as a result break apart the polymer.

If you eat food while hanging upside down, do you think it will still go through the alimentary canal? Give Reasons...
andrew11 [14]

Answer:

Our alimentary canal undergo a process or a movement called peristalsis, in which the walls continuously move to pass the food downwards. So if you eat hanging upside down, the food would surely move.

Explanation:

  • Peristalsis is a series of wavelike muscle contractions that moves food to different processing stations in the digestive tract and the process begins in the oesophagus when a bolus of food is swallowed.
  • The muscles of the oesophagus are strong enough to propel food and liquids into the stomach even when hanging upside down although there is a risk of choking
  • It is advised that maintaining a correct body positioning during eating is very important for digestion to happen properly and avoid blockage of the airways by food and fluid.
  • Leaning your body upright slightly and rounding your shoulders a bit so that your chin is tucked-up is a way of exercising safe chewing and swallowing.
