Answer;
-Correlational; experimental
Two main types of designs used specifically in human lifespan studies are correlational and experimental.
Explanation;
-Psychological studies vary in design. In correlational studies a researcher looks for associations among naturally occurring variables, whereas in experimental studies the researcher introduces a change and then monitors its effects.
-An experiment isolates and manipulates the independent variable to observe its effect on the dependent variable, and controls the environment in order that extraneous variables may be eliminated. Experiments establish cause and effect. A correlation identifies variables and looks for a relationship between them.
The gibberellic acid solution is the dependent variable because it is the only variable that changes in each scenario.
Any of the other variables (fertilizer, soil) are independent, as they are constant throughout.
The control group is flask 1 because it had a 0% gibberellic acid solution (the dependent variable) added as opposed to the other amounts greater than 0 in the other flasks.
The premises that reinforce the thesis "the human drift", statement are A) 1, 2, and 3.
- The objective of a thesis statement, which often consists of one or two phrases, is to lead the author so that he or she doesn't lose focus while also educating the reader about the author's viewpoint and the topic of what will be read by the man.
- The thesis statement in the "The Human Drift" passage by Jack London reveals that the topic under discussion will be how humans have improved upon and become more proficient at killing.
- The thesis statement should be supported and reinforced by the premises. In this instance, the thesis statement will be well supported by any premise that demonstrates the development of man's killing techniques and the diversity of his prey.
- Those are the exact things that sentences 1, 2, and 3 do. They discuss how man kills to maintain his dominance over other species, how killing tools were created perhaps too early in man's history, and how man has improved to the point where he can kill germs.
