Answers:
- the amount of sunlight received by different branches of the tree
- the presence of pests or diseases affecting some of the apples

Reason: Light exposure varies by branch and affects fruit size, and pests/disease can reduce growth of some fruits. Fertilizer is applied to the whole tree (so not a within‑tree source of variability), and apples on the same tree are generally genetically the same (especially on grafted trees), so genetics is unlikely to explain within‑tree weight differences.
