Susan is conducting an experiment to see if plants will grow better with application of fertilizer. she separates 50 plants into two groups of 25. one group receives a liquid fertilizer when watered every other day, and the other group receives only water on the same days. the plants are kept in a greenhouse with constant and equal amounts of sunlight, and a constant temperature. she measures the plants once a week for 12 weeks. at the end of 12 weeks, the plants with the fertilizer grew an average of 9 inches, and the ones that were not given the fertilizer grew an average of 5 inches. in this scenario, the plants that received fertilizer are the group, and the plants that did not receive fertilizer are the group. contro

First blank: Experimental or test

Second blank: Control group

Explanation:

To distinguish control versus experimental group just remember that in a control group the independent variable is controlled or held constant. In the experimental group the independent variable is changed.

In other words, the experimental group is the group that receives the treatment, or test.

This type is done to isolate the effects of the independent variable. What happens all variables in both groups are kept the same. The only difference is the independent variable should change in one to reliably determine whether the changes in the dependent variable(in this case plant growth) was caused by the independent variable (fertilizer).

post-impressionism is a predominantly french art movement that developed roughly between 1886 and 1905, from the last impressionist exhibition to the birth of fauvism. post-impressionism emerged as a reaction against impressionists' concern for the naturalistic depiction of light and colour.
