Answer:
Check Explanation.
Explanation:
So, the question is about a research or an experiment on whether the intake of cola causes a lot of or severe headaches. And I will be using myself as the control experiment. Please note that I just did not want to use myself as the control experiment but because the question ask us to. That is the use of "single case design" which means that the person performing the experiment must use himself or herself as the control experiment instead of using another person.
Step one => I will make sure to know how often or how many times I do do get headaches.
Step two => I will then stop taking the cola, but after sometimes I will continue taking the cola back.
Using the single case design, I can test for my Hypothesis using the following steps;
For step two above, if during the period that I stopped taking cola, I did not have any headache and immediately I start taking the cola I started developing headaches, then
it is true that the artificial sweetener in the cola is responsible for the headaches.
To the second part of the question; I expect to find that that the artificial sweetener in the cola is responsible for the headaches.
My conclusion will be that the artificial sweetener in the cola is responsible for the headaches.
Answer:
Environmental justice involves the fair treatment and meaningful involvement of all people regardless of race, color, national origin, or income, with respect to the development, implementation, and enforcement of environmental laws, regulations, and policies.

Some of the topics addressed by environmental justice are responsible use of land and renewable resources, cessation of production of hazardous materials and toxic or radioactive waste, and right to work at a safe and healthy place, among others.
Answer:
independent groups
posttest only
pretest/posttest
Explanation:
Posttest-only and pretest/posttest are the two elementary structures for experiments with independent-groups designs.
A posttest only design is most useful when spontaneous behavior is required from the participants.
Pretest-posttest designs developed from the posttest only design to consider issues of assignment bias and allocation of the participants, as they can avoid selection effects.
