1) The two functions of mucus along the alimentary canal are:
- Lubrication: Mucus helps to lubricate the food particles, making it easier for them to move through the digestive system.
- Protection: Mucus helps to protect the lining of the alimentary canal from acidic substances, enzymes, and mechanical damage.
2) Assimilation and absorption are two different processes in digestion:
- Assimilation: Assimilation refers to the process by which digested nutrients are absorbed into the bloodstream and used by the body's cells to support various physiological functions.
- Absorption: Absorption refers to the process by which the digested nutrients and water are taken up by the cells lining the small intestine and transferred into the bloodstream for distribution throughout the body.
3) A food that helps peristalsis is fiber-rich foods, such as whole grains, fruits, and vegetables. Fiber adds bulk to the stool and helps stimulate the muscle contractions of peristalsis, promoting regular bowel movements.
4) The end products of the light stage of photosynthesis are ATP (adenosine triphosphate), NADPH (nicotinamide adenine dinucleotide phosphate), and oxygen. During the light stage, light energy is converted into chemical energy in the form of ATP and NADPH, and oxygen is released as a byproduct.
5) The end products of the dark stage (or Calvin cycle) of photosynthesis are glucose and other organic molecules. During the dark stage, ATP and NADPH produced in the light stage are used to convert carbon dioxide into glucose through a series of enzymatic reactions.
