Answers
Answer:
1.beans would take a longer time because sugar is already in a simplified form and can be easily converted to glucose whereas beans contain proteins and therefore takes a longer time to digest.
2.digestion needs the help of two more system in the body to provide energy from food. ... The circulatory system helps in the transportation of absorbed nutrients and oxygen to the tissues for respiration while the respiratory system oxidises the food to release energy.
3.Yes. Even if we eat food while hanging upside down, it will go through the alimentary canal because of the process of peristalsis. The muscles of the oesophagus will push the food downwards in a wave like action throughout the alimentary canal.
