18. A student wants to find the benefit of a certain trait in mice. What is the first step the student should follow in order to scientifically investigate the mouse trait? A. Collect data on the survival rate of mice with and without the trait. B. Conduct background research the genetics of mouse traits. C. Breed mice with and without the trait together in nature. D. Design an experiment to investigate the mouse trait.

<p> The scientific method is a logical and systematic procedure followed by in experimental investigations to establish theories and laws. On of the first steps in this process always involves conducting background research on the subject under consideration. This research allows a student to define a problem or question, and hypothesise a potential solution/ answer. Therefore, a student aiming to find the benefit of a certain trait in mice for the first time needs to conduct background research on the genetics of mouse traits (Option B) offers the best initial approach. Like any other investigations in biology, understanding background information determines the best approach. </p>
