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. As body temperature rises, sweating occurs to cool the body:
An example of negative feedback, where the body counters a change to restore normal state.
B. After drinking large amounts of water, urine output decreases to raise blood volume:
Urine output would actually increase to excrete the excess water and maintain volume.
C. Decreases in blood pressure cause a corresponding decrease in heart rate:
A decrease in blood pressure should cause the heart rate to increase (compensatory response).
D. As blood pressure falls, blood flow to the heart decreases:
The body usually increases heart rate and vasoconstriction to maintain cardiac output.
Correct Answer is B
Explanation
A. exocytosis: This is the process of expelling material out of the cell, not taking it in.
B. pinocytosis: Pinocytosis is "cell drinking"-the process of engulfing dissolved particles in fluid by invagination of the plasma membrane.
C. cytolysis: Cytolysis refers to cell bursting, not intake of particles.
D. phagocytosis: Phagocytosis is "cell eating", where the cell engulfs large solid particles like bacteria, not liquids.
