1. there are more than one variable that are manipulated; sunlight and fertilizer
2. If provide fertizlier to both plants; placed in sunlight and placed in dark
3. By measuring height of the plant and production of the fruit.
Explanation:
In this investigation, one plant X is placed in sunlight and provided fertilizer where the plant Y placd in the dark did not received fertilizer, so there are two variables that are manipulated in this setting, which can influence the result in the study.
To make this experiment one shuld provide fertilizer to both the plants for control environment and no other infunces to affect the growth of the plants.
To measure the growth of the plant one can measure the height and fruit production each week to compare the difference in growth rate.
