17. victoria grows the same bacteria in 20 petri dishes. she places 10 of the dishes in a container with a normal atmosphere. the remaining dishes she places in a container in which the oxygen level is double the normal level. she labels the first group a and the second group b. which statement best describes the groups? group a is the experimental group, group b is the control group group a is the theoretical group, group b is the hypothetical group group a is the control group, group b is the experimental group

17. victoria grows the same bacteria in 20 petri dishes. she places 10 of the dishes in a container with a normal atmosphere. the remaining dishes she places in a container in which the oxygen level is double the normal level. she labels the first group a and the second group b. which statement best describes the groups? group a is the experimental group, group b is the control group group a is the theoretical group, group b is the hypothetical group group a is the control group, group b is the experimental group

Answer

Brief Explanations:

In a scientific experiment, the control group is the one that is not exposed to the variable being tested. Here, Group A is in a normal atmosphere (no change in oxygen - level variable), while Group B has a double - normal oxygen level (the variable is changed). So Group A is the control group and Group B is the experimental group.

Answer:

C. Group A is the control group, Group B is the experimental group
