The 3Rs by Russell and Burch are known to be the "alternative methods" to improve the treatment of laboratory animals, at the same time to advance the quality of science that uses animals for studies.
The 3Rs are Replacement, Reduction, and Refinement. Replacement is defined as minimizing the pain and suffering of the animals used in research. Reduction is for reducing the number of animals being used, and using healthier animals. Replacement is using alternative to animals such as tissue cultures and computer models.
The correct answer is B) observation.
Among the four methods, the method of data collection that is involved when an individual counts the number of vehicles passing designated locations on the Los Angeles freeway system is observation.
When researchers use the method of observation to collect information, this means that a person acts as the observer, he or she is physically in the location to observe the phenomena. In this case, an individual is placed in a specific part of the freeway to observe and count the number of vehicles that cross the designated location.
Culture doesn't really have aims; it's an by-product of human social behaviour, something that people create as they live in groups and satisfy their other needs. It's functions are to "remember" certain behaviours that worked in the past, such as certain ways of preparing food.
