The larvae (caterpillars) of a species of insect that feed on leaves of a tree were used in this investigation. The larvae were fed for 30 days on either green leaves or yellow leaves. The bar-diagram below shows the mean mass of the larvae, after feeding them for 30 days. Study the above chart and choose the CORRECT statement(s).

Options

1. AFemale larvae, on an average, have higher mass than male larvae.
2. BYellow leaves may have some chemicals that contribute to the differential increase in mass between male and fe
3. CThe increase in the mean mass of the larvae is governed by more than one factor.
4. DThe proportionate increase after feeding, the mean mass in female larvae is always more, compared to that of m
