Answers
Answer:
a.Holozoic nutrition is a method of nutrition that involves the ingestion of liquid or solid organic material, digestion, absorption and assimilation of it to utilize it. It includes taking in the complex substances and converting them into simpler forms.
b.the whole passage along which food passes through the body from mouth to anus during digestion.
2.a.the absorption and digestion of food or nutrients by the body or any biological system.
b.The process of rechewing the cud to further break down plant matter and stimulate digestion is called rumination
3.The alimentary canal includes the mouth, pharynx, esophagus, stomach, small intestine, large intestine, and anus.
4.
1. Milk teeth (baby teeth) :
1. Root canals have a more hour-glass-like appearance
2. A larger pulp chamber
3. A high degree of cellularity and vascularity
4. Blood supply is abundant, flowing through the enlarged apical foramens
5. The formation of dentine tubules is less regular
6. Inter globular dentine is absent
7. Enamel and dentine are less mineralized
2.permanent teeth
1. Root canals have a well-defined appearance with more branches
2. A smaller pulp chamber
3. A low degree of cellularity and vascularity
4. Blood supply is restricted and reduced
5. The formation of dentine tubules is more regular
6. Inter globular dentine is present
7. Enamel and dentine are more mineralized
5.Human teeth include incisors, canines, premolars, and molars.
6.Incisors – The four front teeth in both the upper and lower jaws are called incisors. ...
Premolars (Bicuspids) – These teeth are located behind and adjacent to the canines and are designed to crush food. ...
7.Stomach acid plays an essential role in the immune system by killing harmful bacteria and parasites that are ingested with food. Stomach acid activates the enzyme pepsin needed for protein digestion. Stomach acid signals to the pancreas produce digestive juices and enzymes to further break down food.
8.(1)The bile juice works as a medium to break down fats from larger parts to smaller parts of body for digestion. (2)The bile juice also functions as a substance that eradicates the germs from the food, making it more hygienic for our body.
(2)When food enters the duodenum, it is deluged with pancreatic juice, which is defined as an alkaline secretion of the pancreas containing enzymes that aid in the digestion of proteins, carbohydrates and fats. ... This pancreatic juice contains enzymes that complete the digestion of starch called pancreatic amylase.
hope this helps :)
