Given below are certain groups of terms. In each group the first pair indicates a relationship between the two terms. Rewrite and complete the second pair on a similar basis. Example: Cytoplasm : Cytokinesis :: Nucleus : Karyokinesis.
Widening of hips : Oestrogen :: Deepening of voice in males : __________
Topic: Testosterone
Answer
TESTOSTERONE.
The relationship is SECONDARY SEXUAL CHARACTERISTIC : HORMONE RESPONSIBLE. Widening of the hips is a female characteristic caused by oestrogen, so deepening of the voice is the male characteristic and testosterone is its hormone.
Testosterone is secreted by the LEYDIG (interstitial) cells of the testis and produces all the male secondary sexual characteristics — facial and body hair, a deepened voice from the enlarged larynx, broad shoulders and muscular development.
THE METHOD for every analogy question: state the relationship of the first pair IN WORDS before attempting the second. Here it is "characteristic : hormone causing it", and the answer follows at once.
