Question

monosaccharides are the building blocks of carbohydrates. they may be found alone or combined with other molecules in fruits, vegetables, dairy products, and grains. the model shows the chemical structures of three monosaccharides: glucose, fructose, and galactose. compare glucose, fructose, and galactose. has 12 hydrogen and 6 oxygen atoms is a monosaccharide has a 6 - atom ring

Explanation:

• For "has 12 hydrogen and 6 oxygen atoms": Looking at the chemical formulas \(C_6H_{12}O_6\) for all three (glucose, fructose, galactose), we can count the atoms. In \(C_6H_{12}O_6\), there are 12 hydrogen (\(H\)) and 6 oxygen (\(O\)) atoms. So all three (glucose, fructose, galactose) should be checked for this property.
• For "is a monosaccharide": The problem statement says "Monosaccharides are the building blocks of carbohydrates. The model shows the chemical structures of three monosaccharides: glucose, fructose, and galactose". So all three (glucose, fructose, galactose) are monosaccharides and should be checked.
• For "has a 6 - atom ring": Looking at the chemical structures (glucose has a 6 - atom ring, fructose has a 5 - atom ring, galactose has a 6 - atom ring). So glucose and galactose should be checked for this property.

Answer:

• has 12 hydrogen and 6 oxygen atoms: glucose (check), fructose (check), galactose (check)
• is a monosaccharide: glucose (check), fructose (check), galactose (check)
• has a 6 - atom ring: glucose (check), fructose (uncheck), galactose (check)
