What would you say is true of the following reaction:
maltose (C12H22O13) + H2O -> glucose (CH12O) + glucose (C2H12O)
it is a decomposition dehydration reaction
it is an anabolic reaction
it is an exchange reaction
it is a decomposition hydrolysis reaction
it is a synthesis dehydration reaction
The Correct Answer is D
A. it is a decomposition dehydration reaction: Dehydration removes water, but this reaction adds water (H₂O).
B. it is an anabolic reaction: Anabolic reactions build larger molecules from smaller ones. This reaction is breaking a molecule apart.
C. it is an exchange reaction: Exchange reactions involve swapping parts between molecules—not just splitting.
D. it is a decomposition hydrolysis reaction: This is a decomposition (breaking down) reaction using hydrolysis (water added to break bonds).
E. it is a synthesis dehydration reaction: That would involve joining molecules together and removing water, which is not the case here.

Correct Answer is A
Explanation
A. positively charged; cations: Sodium (Na), potassium (K), and calcium (Ca) are metals that lose electrons, becoming positively charged ions, called cations.
B. negatively charged; cations: Cations are always positive. A negative ion is an anion.
C. positively charged; anions: The term anion refers to a negatively charged ion, not a positive one.
D. negatively charged; anions: These elements do not gain electrons-they lose them and do not become anions.
Correct Answer is C
Explanation
A. Anterior:
This means “front” of the body in general, but is too broad and non-specific. The abdomen is located on the anterior side, but “ventral” is the more precise term in this context.
B. Distal:
Means farther from the point of attachment; applies to limbs, not the torso/abdomen.
C. Ventral:
The ventral cavity includes the thoracic and abdominopelvic cavities. A shot to the abdomen involves the ventral aspect of the body.
D. Brachial:
Refers to the upper arm area – unrelated to the abdomen.
E. Proximal:
Means closer to the point of attachment; again, more relevant to limbs.
