Answer:
Independent Variable - Soil, Dependent Variable - Height, Control Variable - Sun and Water
Explanation:
First we should define what the variables in the experiment are.
Independent variable is the aspect of the experiment that has a different value for each subject in order to find out how it affects the dependent variables.
Dependent variable is the variable that is kept under observation and recorded by the experimenters in order to track the changes and define its relationship with the other variables/parameters.
Control variable is the variable that is kept constant intentionally by the experimenters to be able to define the relationship between the other variables more clearly and easily.
In the example given in the question, there are one of each variable mentioned above which are, according to the definitions;
- Independent Variable - The Soil
- Dependent Variable - The Height Of The Plant
- Control Variable - The Amount of Water and Sun Exposure

The correct answer is A) A roast at 125°F (52°C)
Explanation:
In general terms, bacteria thrive at warm temperatures; this means bacterial growth is lower at extremely hot/cold temperatures, but it is higher at warm or medium temperatures. Indeed, the ideal temperature for bacteria to develop and reproduce is between 4° C and 60°C. This implies from the options given the roast at 52°C represents an ideal temperature for the growth of bacteria. Also, other options include temperatures above 60°C, and therefore do not allow bacteria to grow well.
