Answer:
1) All prey get swallowed whole bcz frogs can't chew. Some frogs catch prey with a long sticky tongue. Tongueless frogs use their fingers to catch their pray.
2)Spiders digest their food outside their bodies. After their pray is captured, spiders expel digestive enzymes from their intestinal tract onto the victim. The enzymes break down it's body and tissues, after that spider sucks the predigested tissues.
3)The alimentary canal is a long tube of organs — including the esophagus, stomach and intestines —that runs from the mouth to the Anus.
4)colour– baby teeth are whiter than permanent teeth.
Rougher edges– Baby teeth are smooth on the bottom and permanent have a jagged bottom edge.
5)Saliva is the watery and usually somewhat frothy substance produced in the mouth of some animals, including humans.
Produced in saliva glands.
6)The function of taste buds is to allow you to experience tastes such as sweet, sour, etc.
7)It takes about six to eight hours for food to pass through your stomach to the small intestine.
8)This acids creates a low pH environment in the stomach. The stomach acids helps in the digestion of food by degrading the food molecules, activate stomach proteases.
