Match the following. Column I Column II 1. Carbohydrates (a) Amino acids 2. Proteins (b) Peristalsis 3. Ruminants (c) Glucose 4. Oesophagus (d) Insects 5. Frog (e) Cud

1-(c) The partially digested food reaches the lower part of the small intestine which secretes intestinal juice. Intestinal juice digests the partially digested food to convert it into the simplest form. The carbohydrates get converted into the simplest sugars known as glucose. 2-(a) Digestion of proteins begins in the stomach. Amino acids are the building blocks of proteins. They're needed for vital processes like synthesis of hormones and neurotransmitters. 3-(e) Cud is a portion of food that returns from a ruminant's stomach to the mouth to be chewed for the second time. 4-(b) The walls of the oesophagus show muscular movement to enable the food to enter into the stomach. This muscular movement is called peristalsis. 5-(d) Frogs catch insects, which are their food. A frog has a long sticky tongue which is attached to the front of the mouth. Hence, the correct match the following is: Column I Column II 1. Carbohydrates (c) Glucose 2. Proteins (a) Amino acids 3. Ruminants (e) cud 4. Oesophagus (b) Peristalsis 5. Frog (d) Insects
