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. chemical structure diagrams of glucose, fructose, galactose glucose c₆h₁₂o₆ fructose c₆h₁₂o₆ galactose c₆h₁₂o₆ compare glucose, fructose, and galactose. chart with rows: has 12 hydrogen and 6 oxygen atoms, is a monosaccharide, has a 6 - atom ring and columns: glucose, fructose, galactose with checkboxes

Explanation:

1. For "has 12 hydrogen and 6 oxygen atoms": Check the chemical formula \( C_6H_{12}O_6 \) for each. Glucose (\( C_6H_{12}O_6 \)), fructose (\( C_6H_{12}O_6 \)), and galactose (\( C_6H_{12}O_6 \)) all have 12 H and 6 O atoms. So all three columns (glucose, fructose, galactose) get a check.
2. For "is a monosaccharide": The text states all three (glucose, fructose, galactose) are monosaccharides. So all three columns get a check.
3. For "has a 6 - atom ring": Glucose and galactose have 6 - atom rings (count the atoms in the ring: 5 carbons + 1 oxygen for glucose? Wait, no, looking at the structures: glucose's ring has 6 atoms (including O), fructose's ring has 5 atoms (4 carbons + 1 O), galactose's ring has 6 atoms (5 carbons + 1 O). So glucose and galactose have 6 - atom rings, fructose does not. So glucose and galactose columns get a check, fructose does not.

Answer:

	glucose	fructose	galactose
is a monosaccharide	✔️	✔️	✔️
has a 6 - atom ring	✔️	❌	✔️
