Answer: Mouth.
Explanation:
The mouth is known to be performing both the tasks of chemical digestion and mechanical digestion.
The food is ingested through mouth and the teeth perform the process of mechanical digestion by breaking down the food particles into smaller particles.
Then the saliva gets mixed into the food and the enzymes(amylase) present in the saliva helps in the digestion of carbohydrates.
So, mouth is the organ that performs the process of both mechanical and chemical digestion.
Any theory must contain a meaningful concept with new evolution to accept by the scientific community
Answer:
Different from one another.
Explanation:
Both rocks are different from one another because one rock is formed from small pieces of rock while the other is made of liquid rock. Due to formation from different types of materials both rocks are different from one another. If both rocks are formed from small pieces of rock or liquid rock, then we can say that both rocks are similar to each other in composition.
