Answer 1

Answer:

Various alternatives to the use of animals have been suggested, such as in vitro models, cell cultures, computer models, and new imaging/analyzing techniques (Balls, 2002). The in vitro models provide the opportunity to study the cellular response in a closed system, where the experimental conditions are maintained.
