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.

The steps that should follow directly AFTER a scientist makes an observation are to **begin background research and ask a question**. This step helps the scientist understand the context of their observation and formulate a specific question to investigate further.

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.
Answered by GPT-4o mini
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.
Answered by GPT-4o mini
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.
