This is an example of experimental control. In this scenario, the group that receives the pill represents the experimental group, while the group that does not receive the pill serves as the control group. Experimental control is essential for isolating the effects of the treatment being tested.

Scientific knowledge can be re-examined by new investigations.

Scientific knowledge can be published in new publications.

Scientific knowledge can be published in new publications.

Scientific knowledge can be argued.

The statement that BEST describes how scientific knowledge can change is: Scientific knowledge can be re-examined by new investigations. This highlights the dynamic nature of science, where new evidence or perspectives can lead to changes or refinements in existing knowledge.

The correct response is law. A scientific law describes how elements of nature behave under specific conditions, typically stated in a concise mathematical or verbal form, but it does not explain why these phenomena occur.

To test their hypothesis about starfish biodiversity, a scientist removed starfish from specific intertidal pools and then measured the diversity every month for an extended period. What step in the scientific method does this methodology describe?

(1 point)
Responses

forming a hypothesis

forming a hypothesis

doing background research

doing background research

conducting an experiment

conducting an experiment

making observations

The methodology described relates to conducting an experiment. The scientist is testing their hypothesis by manipulating a variable (removing starfish) and measuring the effects on biodiversity over time, which is a key aspect of conducting an experiment in the scientific method.
