Answer:

<h3>Oesophagus</h3>

Explanation:

  • The oesophagus is the region of the alimentary canal where the food passes without the absorption of nutrients. In oesophagus, we find peristaltic movement which is basically rhythmic contraction and relaxation of the oesophagus in order to facilitate the easy passage for the food to pass from mouth to stomach.
  • The oesophagus is a muscular tube which measures about 8 inches long.
  • Mucosal lining lines the oesophagus.

Answer:

a .carbon dioxide(Co2) and water (H2O)

b. air and soil

Explanation:

During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
