Which of the following starts to break down as soon as they enter the mouth?
MissTica

The answer is carbohydrates.

Food  in  the mouth is moistened and lubricated  with saliva. Saliva contains an enzyme called salivary amylase. 

Salivary amylase is an enzyme that breaks down complex carbohydrates molecules into simple or smaller carbohydrate molecules  called maltose. The enzyme acts on carbohydrates in the mouth, initiating the process of digestion.

Salivary amylase  is made by the salivary glands in the mouth. Maltose is later converted to glucose in the small intestine by another type of amylase called pancreatic amylase.

Which type of information is pseudoscience based on?
OlgaM077 [116]

Answer:

Unsupported claims

Explanation:

Pseudoscience is kind of a <em>fake </em>science. it uses scientifical terms to trick people into thinking it actually <em>is </em>science. It uses words like "quantum" in a sentence such as "Buy this quantum phone charger for your phone to charge 2x the normal speed!" Since it has the "quantum" in it, some people do actually think it's scientific, and fall for that ad.

So, the answer is unsupported claims because those claims such as "Drinking milk and eating mango at the same time lead you to death" are fake beliefs that don't have any scientifical evidence.
