Answer:
The digestion starts with the buccal cavity or mouth by chewing the food. Teeth break the ham and cheese sandwich into small and digest the starch present in the food with help of the amylase enzyme present in saliva. The small chewed particles of food mixed with saliva called bolus move to the stomach.
In the stomach, there is HCl acid present that killed any harmful microorganism present in the bolus and digests the protein present in the ham and sandwich by pepsin enzyme secreted by the parietal cells of the stomach.
Lipase digest fat present in the cheese of sandwich by gastric juice. Small intestine digest fat by lipase protein by protease and carbs by amylase.
Absorption takes place in the small intestine that contain numerous villi’s projections in the cell lining for absorption in the small intestine.
Answer:
Mutations can be defined as changes that occur in the genetic material (DNA) of living organisms. These changes are an important source of genetic variability, and are often responsible for the emergence of new species. Changes in genetic material are extremely important, as it is DNA that carries the information necessary for protein synthesis. Some modifications in the genes directly affect the protein to be synthesized, resulting in the appearance of an unexpected characteristic. It is worth noting that mutations in DNA can cause everything from physical changes to behavioral changes. This way, he has to focus on the DNA of the cell.
