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. 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; columns: glucose, fructose, galactose, with checkboxes

Explanation:

For "has 12 hydrogen and 6 oxygen atoms" row:

• Check the formula of each monosaccharide. Glucose, fructose, and galactose all have the formula \( C_6H_{12}O_6 \), which means each has 12 H and 6 O atoms. So all three (glucose, fructose, galactose) should be checked.

For "is a monosaccharide" row:

• The problem states that glucose, fructose, and galactose are monosaccharides (they are the building blocks of carbohydrates and the model shows them as monosaccharides). So all three should be checked.

For "has a 6 - atom ring" row:

• Look at the structures:
• Glucose: The ring structure (the hexagonal ring) has 6 atoms (5 C and 1 O), so it has a 6 - atom ring.
• Fructose: The ring structure is a pentagonal ring (4 C and 1 O), so it does not have a 6 - atom ring.
• Galactose: The ring structure (hexagonal ring with 5 C and 1 O) has 6 atoms, so it has a 6 - atom ring.

Filling the table:

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

(Note: If the checkboxes are to be marked as per the above, for each row:

• "has 12 hydrogen and 6 oxygen atoms": All three columns (glucose, fructose, galactose) have the property, so mark their checkboxes.
• "is a monosaccharide": All three are monosaccharides, mark their checkboxes.
• "has a 6 - atom ring": Glucose and galactose have 6 - atom rings (hexagonal rings), fructose has a 5 - atom (pentagonal) ring, so mark glucose and galactose checkboxes, leave fructose unmarked.)
