Question

read the science textbook excerpt and then answer the question.
genes and behavior
in the 1940s, behavioral psychologist robert tryon
conducted an experiment in which rats were placed in a
complex maze that had a food reward at one exit. rats that
made fewer errors navigating the maze were bred together
to create a \maze-bright colony.\ rats that made more
errors were bred together to create a \maze-dull colony.\
after selectively breeding the mice for seven generations,
tryon tested offspring from each colony to determine how
quickly those rats would learn the maze. offspring of the
maze-bright rats consistently made fewer errors than the
maze-dull offspring. tryons research therefore suggests
that the ability to navigate the maze successfully was
influenced by genes passed from parent to offspring.
who is the primary audience?
people who own pet rats
professional psychologists
genetics researchers
biology students

Explanation:

The excerpt is a science textbook passage about an experiment linking genes and behavior. Textbooks are typically designed for students learning the subject. Biology students study genetics and behavior connections, which aligns with the content. Pet rat owners, professional psychologists, and genetics researchers are less likely to be the primary audience for a basic textbook excerpt.

Answer:

biology students
