Answer:
<u>No, there is no control group.</u>
Explanation:
To test various theories, experiments are usually conducted under a number of different conditions. Several considerations must be established when planning studies to ensure reproducibility, accuracy, and validity of findings.
For example, while controls are kept constant, or unmanipulated. Also, separate independent variables are strictly altered and analyzed - this guarantees validity and may show whether external influences affected the experiment. Here the variable being altered or measured is the food, and the resultant weight is the factor being observed.
Responding to the environment is a characteristic of the life best shown by a living organism.
