Question 28 GCE_MODEL_QUESTIONS_VOL1 • 2019 • BIOLOGY • objective

A desert shrub has cylindrical stems that are 10 cm long and 2 cm in diameter. A closely related mesic (moist‑habitat) species has stems of the same length but a diameter of 5 cm. Assuming water loss is directly proportional to stem surface area (ignoring the ends), calculate the ratio of total water loss of the desert shrub to that of the mesic species. Explain how this ratio reflects an adaptation to arid conditions.

Answer Options

Correct Answer A. 0.4 (the desert shrub loses 40 % of the water lost by the mesic species).
B. 1.5 (the desert shrub loses 150 % of the water lost by the mesic species).
C. 0.6 (the desert shrub loses 60 % of the water lost by the mesic species).
D. 0.25 (the desert shrub loses 25 % of the water lost by the mesic species).
Correct Answer
A
Correct Option:
0.4 (the desert shrub loses 40 % of the water lost by the mesic species).
