In a research project investigating power relationships in speech, first-semester college freshmen and college seniors were invited to a laboratory in equal numbers. there, they were asked to chat and get to know each other before the real experiment began. the researchers actually analyzed the number of interruptions that people made in the course of a conversation. this is an example of research.

laboratory observation

Explanation:

Laboratory observation occurs when researchers gather a group of people to be participants in their tests, so that investigators execute their experiments as similarly as possible to real life but in a controlled environment. Therefore, researchers can regulate the setting and reduce outside influences.

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
