Drag the tiles to the boxes to form correct pairs. Raya is a gardening enthusiast who is looking to buy a new house. She wonders whether her house plants will grow well if she buys an apartment on a higher floor. She remembers that her friend Jenn also has a small garden on her balcony, and her plants seem healthy.

Raya conducts an experiment to study the effect of altitude on the growth of plants. She gathers plant samples and places them on five different floors of a 20-story building. Identify the basic components of Raya’s experiment, including the confounding variable.

1.  the altitude -  Independent variable

2.  the growth of plants  - Dependent variable

3. the amount of water and nutrients -  Constant variable

4. the storeys of the building - Confounding variable

Explanation:

The fundamental parts of a scientific investigation or experiment are the kinds of factors remembered for the examination which are needy (to be contemplated), autonomous (can be changed) and the steady factors (stay same).  

The trial is likewise affected by another variable known as confounding variable which straightforwardly impact these essential factors and can cause or produce the futile outcomes in a test.

In the given question,

1.  the altitude -  Independent variable

2.  the growth of plants  - Dependent variable

3. the amount of water and nutrients -  Constant variable

4. the storeys of the building - Confounding variable
