Answer:
The correct answer is- digestion, absorption, transport, elimination
Explanation:
The process of digestion starts from the mouth with the help of enzymes called salivary amylase present in our saliva. The food then passes through the esophagus to the stomach.
In the stomach, the food is broken down in small fragments by churning movement which mixes digestive enzymes and food to form chyme.
This chyme is passed to the small intestine where several enzymes from the liver and pancreas digest the food in smaller particles and absorb these particles in the blood. Therefore absorption takes place in the small intestine.
Then the solid waste material left behind after absorption is transported from small intestine to the large intestine and from large intestine waste is eliminated out of the body.
Therefore the correct order are: digestion → absorption→ transport→ elimination.
Answer:
Following information are needed to classify an organism.
1. Unicellular or multicellular : First we have to see that from how many cells the body of organisms formed.
2. Composition of cell wall: Secondly we have to see the cell wall composition.
3. Prokaryotic or eukaryotic cell: We have to see the nucleus of organisms, if it has nucleus we can say that it is a eukaryotic cell.
4. Mode of nutrition: Mode of nutrition means is the organisms is autotroph or heterotroph.
If they have similarities, so it is placed in one group. If not so it is placed in different group or kingdom.
