Sooo easy questions first tell me u are which class tell then I will ans ok
Answer:
1) State the role of acid in the human stomach.
➡The hydrochloric acid found in the stomach facilitates the process of digestion by disintegrating complex large food molecules to simpler molecules.

(2) State the function of the (a)Incisor teeth
➡ primary function is to cut food. The two incisors on either side of the midline are known as central incisors. The two adjacent teeth to the central incisors are known as the lateral incisors.
b) Premolar teeth:
➡These teeth are located behind and adjacent to the canines and are designed to crush food.

(3) Explain ingestion of food, in amoeba, through a diagram.
➡Ingestion is the process of taking food in the body. As Amoeba is an unicellular organism, so it doesn't have a mouth for ingestion of food. Thus, Amoeba ingests the food by encircling it by forming 'Pseudopodia' (P is silent). As the cell membrane of the pseudopodia fuse, the food gets trapped into a food vacuole

4) Why is Nutrition important for a living organisms?
➡Nutrition is the essential organic nutrients living organisms require for growth, maintenance, reproduction and repair. This is an essential process for theorganism's survival. Living organisms require energy to survive; this energy is derived from nutrients, or food.
