Which of the following is mismatched?
anaphase--sister chromatids are pulled to separate ends of the cell
metaphase -- chromosomes line up at the center of the cell
telophase -- nuclear envelope is breaking down; chromosomes are condensing
interphase -- cell is going about its daily business, at the end DNA is duplicated and starts condensing
The Correct Answer is C
A. anaphase – sister chromatids are pulled to separate ends of the cell: During anaphase, sister chromatids separate and move to opposite poles.
B. metaphase – chromosomes line up at the center of the cell: In metaphase, chromosomes align at the metaphase plate.
C. telophase – nuclear envelope is breaking down; chromosomes are condensing: In telophase, the nuclear envelope is reforming, and chromosomes are de-condensing into chromatin. The description given fits prophase, not telophase.
D. interphase – cell is going about its daily business, at the end DNA is duplicated and starts condensing: During interphase, the cell grows and replicates DNA in preparation for mitosis.

Correct Answer is D
Explanation
A. anterior to her shoulders: Anterior means in front of the body. During a pole vault, Stacy’s hips are typically above her shoulders, not in front.
B. posterior to her shoulders: Posterior means behind the body. Her hips are not necessarily behind her shoulders in the motion.
C. inferior to her shoulders: Inferior means below. Her hips are elevated higher than her shoulders mid-vault.
D. superior to her shoulders: Superior means above. In the airborne phase of a pole vault, Stacy’s hips are above her shoulders, making them superior in position.
Correct Answer is B
Explanation
A. enhance changes in the pH of solutions: A buffer does the opposite-it prevents drastic pH changes.
B. resist drastic changes in the pH of solutions: Buffers help maintain stable pH by neutralizing excess acids or bases (e.g., bicarbonate buffer system in blood).
C. have no effect on the pH of solutions: Buffers do affect pH-they stabilize it.
D. make a solution more acidic: Buffers don’t always make solutions acidic; they can neutralize both acids and bases.
E. make a solution more basic: Same rationale-buffers do not push pH in one direction, they resist change.
