<h2>Answer:</h2>
Salivary amylase breaks the chemical bonds of starch to form sugar monomers.
<h3>Explanation:</h3>
- Amylase is one of the digestive enzymes which catalyze the breakdown of starch molecules into its monomers.
- A starch molecule is made of the Glucose molecules which are bonded with each other with glycosidic linkages.
- Salivary glands secrete saliva into the mouth cavity.
- Saliva contains amylase for the digestion of starch are known as salivary amylase.
- Steps in the digestion of sugars start from the action of this enzyme.

I would say the answer is false because they also used information of science to help make things like medicine and fungi and fossils, one of the main things science was used for was chemistry and physics to determine what things could kill humans in the world back in the day.
Hope this helps, Have a good day:), ~Nana!~
Answer:
b. reducing molecules
Explanation:
Nicotinamide adenine dinucleotide (abbreviated NAD +, and also called diphosphopyridine nucleotide and Coenzyme I), is a coenzyme found in all living cells. The compound is a dinucleotide, as it consists of two nucleotides linked through their phosphate groups with a nucleotide that contains an adenosine ring and the other that contains nicotinamide.
In metabolism, NAD + participates in redox reactions (oxidoreduction), carrying electrons from one reaction to another.
Coenzyme, therefore, is found in two forms in cells: NAD + and NADH. NAD +, which is an oxidizing agent, accepts electrons from other molecules and becomes reduced, forming NADH, which can then be used as a reducing agent to donate electrons. These electron transfer reactions are the main function of NAD +. However, it is also used in other cellular processes, especially as a substrate for enzymes that add or remove chemical groups of proteins, in post-translational modifications. Due to the importance of these functions, the enzymes involved in the metabolism of NAD + are targets for drug discovery.
