Explanation:
For question 1:
- Amoeba is an unicellular organism, hence it has no digestive system. It catches food by pseudopodia.
For question 2:
- In humans, the whole digestion process is completed in the small intestine.
For question 3:
- When starch is mixed with iodine solution, it always gives a blue-black color.
For question 4:
- Amoeba is an unicellular organism hence it has no mouth or digestive system and food is captured by pseudopodia.
For question 5:
- The pulp cavity, also known as the root, contains nerves and blood vessels.
For question 6:
- Amino acids bind together and form protein molecules.
For question 7:
- In human beings, the 16 teeth of each jaw consist of 4 incisors, 2 canines, 4 premolars and 6 molars.
For question 8:
- The length of the small intestine in human beings is about 6 meters and 20 feet (average 7 meters) and the large intestine's length is about 1.5 meters.
For question 9:
- An amoeba has no mouth or digestive system, so it catches food particles from the surrounding water by using its pseudopodia, which are temporary finger-like projections of cell surface which fuse over the food.
For question 10:
- The process of taking food from an animal and its utilization in the body is called ingestion.
For question 11:
- The digestion of ground nut oil, which is a lipid containing compound present in food, produces glycerol and fatty acids.
For question 12:
- The cow eats grass and plants which contain cellulose, so the cow is the animal which can digest cellulose carbohydrates present in its food by enzymes which is contained by the symbiotic bacteria.
For question 13:
- Excessive sugar containing food causes tooth decay.
For question 14:
- An amoeba has no mouth or digestive system, so it catches food particles from the surrounding water by using its pseudopodia, which is temporary finger- like projections of cell surface which fuse over the food.
For question 15:
- The millions of tiny out growths on the inner surface of the small intestine are called villi, which facilitate the absorption of nutrients by keeping food in small intestine for longer period of time.
For question 16:
- The fat present in our food is completely digested in the small intestine through absorption of nutrients.
For question 17:
- Carbohydrate can be digested by a cow, but not a man, is cellulose because cow contains symbiotic bacteria which contain enzymes for metabolism of cellulose.
For question 18:
- Starch is digested by the saliva of the mouth.
For question 19:
- The teeth in our mouths, which are for piercing and tearing food, are called canines, which are the sharpest teeth.
For question 20:
- Lizards do not suck nectar from the flowers because they feed on insects.
For question 21:
- Water absorption from the indigested food occurs in the large intestine.
For question 22:
- Protein is made up of amino acids, so the digestion of a particular food- protein in the small intestine produces amino acids.
For question 23:
- Milk is obtained from the animals like cows, buffaloes, goats, etc. not from plants.
For question 24:
- Incisors are the teeth responsible for biting and cutting food.
- These teeth are used when we bite food.
For question 25:
- Mucus, hydrochloric acid and digestive juices are secreted by the inner lining of the stomach.
