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.

Identify what types of of questions that can be answered by science
mamaluj [8]

Answer:

There are many questions that can be answered by science but I will provide some examples below.

Explanation:

Science involves many areas of study, <u>from biology and chemistry to physics and neuroscience</u>. Generating questions and providing answers are the most important steps in science as this process has allowed thousands of scientists to develop new drugs to treat previously-mortal diseases, to protect endangered species, to prevent population declines, to understand the behavior of fauna, among many other remarkable outcomes and discoveries.

In this answer, I will focus on some questions belonging to the life sciences areas that can be answered by science:
