Answer:
U CAN JUST WRITE DOWN SOME POINTS FROM THE INFORMATION I HAVE PROVIDED BELOW.I HAVE EXPLAINED EVERYTHING IN A DETAILED MANNER.
Explanation:
Q.1 )
During digestion, muscles push food from the upper part of your stomach to the lower part. This is where digestive juices and enzymes break down the food that you chewed and swallowed. It prepares it to provide your body with energy. The stomach makes several digestive juices and enzymes that mix with food.
Q.2) Cellulose is the type of carbohydrate that can be digested by ruminants but not by humans because, the cellulose of the food is digested by the action of certain bacteria which are not present in humans
Q.3) Villi are small finger-like outgrowths present that help in the process of absorption. These are located in the inner walls of the small intestine. Its function is to increase the surface area of the small intestinal wall to absorb the digested food
Q.4) Bile is produced in the liver. It helps in the digestion of fats by a process called emulsification
Q.5) Ingestion- Amoeba moves towards the food by making pseudopodia. The pseudopodia surround the food particle and fuse to form the food vacuole, which is then taken inside the cytoplasm.
2. Digestion- The food vacuole is combined with lysosomes that contain the hydrolytic enzymes. These enzymes perform the breakdown of food particles.
3. Absorption- The digested food is then absorbed directly into the cytoplasm from where it will be distributed to the different organelles.
4. Assimilation- The absorbed food is used for the generation of energy. The excess amount is stored in the form of glycogen and lipids in the cytoplasm.
5. Excretion- The undigested food in the food vacuole is excreted out of the cell as the food vacuole fuses with the cell membrane and perform exocytosis.(u can just write the name of the process if there is no need to write the explanation)
Q.6) Overall, the function of the small intestine is to:
1. Churn and mix ingested food, making it into chyme
2. Move the food along its entire length (into the colon)
3. Mix ingested food with mucus (making it easier to move)

Answer:
1 - Stomach: The stomach is a muscular, sac-like organ. The inner lining wall of the stomach produces dilute
hydrochloric acid, gastric mucosa and digestive juices. Dilute hydrochloric acid kills microbes that enter
with the food. The digestive juices help in the digestion of proteins. The gastric mucosa keeps the inner
wall of the stomach safe from the harmful effects of the acids
2 - cellulose , The rumen has microorganisms that
can break down cellulose, a complex carbohydrate present in plants.
3 - Villi are finger-like projections on the inner wall of the small intestine
4 - Liver: It is the largest gland in the body. It produces bile juice that helps in digestion of fats. Bile juice is
stored in a small sac-like organ below the liver called gall bladder. The bile juice from the gall bladder is
secreted into the small intestine.
5 - When Amoeba senses food in its surroundings, it starts moving in that direction with the help of finger-like projections of the body called pseudopodia. The word pseudo means false and the word podia means feet . The false feet surround the food particles and engulf it with a drop of water. The food with a drop of water forms the food vacuole. The vacuole stores the food taken in. Some, digestive juices are secreted into the food vacuole where the food is digested. The digested food is absorbed from the vacuole into the body. The vacuole with the undigested food then moves towards the edge of the body
6 - Small intestine: Most of the digestion of the food happens in the small intestine. The bile juice helps in the breakdown of fats in the food present in the small intestine. The pancreatic juice produced in the pancreas contains digestive juices such as trypsin, amylase and lipase, which convert starch, proteins and fats into smaller molecules such as glucose, amino acids and fatty acids, respectively.d bursts open to throw out the waste.
