Scientists observed that white mice that were fed seeds
appeared to grow more than mice given leafy green and
yellow vegetables. They designed an experiment to test
this hypothesis. They divided 200 mice of the same age.
size, health, and sex into two groups of 100 mice each.
The mice were kept under identical conditions for 14
days. One group was given a diet low in protein. The
other group was given a normal protein diet. The mass of each mouse was recorded
daily for 14 days.
