Astudent is performing a test in which she is trying to see if plants can grow when give coca-cola. she gives one plant water and one identical plant the same amount of coca-cola everyday for 2 weeks. what is the independent variable?

The independent variable is coca-cola.

Explanation:

The experiment shown in the question above wants to assess the influence of coca-cola on plant growth.

As we know every scientific experiment has variables, these variables can be divided between independent and dependent variables. The independent variable is one that does not need the influence of anything to exist, in fact, this variable influences a "result" that will be measured. This result represents the dependent variable, which needs the influence of the independent variable to occur.

In the case of the experiment mentioned above, coca-cola will influence or not the growth of plants, therefore, coca-cola is the independent variable and plant growth is the dependent variable.

this is more of a statement than a question. is there answers to go along with this, or is it opinion based?

1. is geographic distribution

2 is increasing complexity

3 is transitional forms
