Question

the effect of perfume on the behavior of bees
description: joanna read that certain perfumes would cause bees to leave the hive and act in an agitated fashion. she decided to investigate the response of bees to five different perfumes- ralph lauren, armani, mark jacobs, vera wang, and an odorless liquid. she placed a saucer containing 20ml of perfume a 10 meters from a beehive. she then recorded the total number of bees that emerged from the hive during a 15 - minute interval and made observations on their behavior. using a 30 - minute interval between tests to allow recovery time for the bees, she then repeated the procedure to test the remaining three samples. each test was conducted on the same day with similar weather conditions.
which of the following is the dependent variable (dv)?
the bees
the type of perfume
the response of the bees
conducting the tests on the same day with similar weather conditions

Explanation:

A dependent variable is what is being measured and affected in an experiment. Here, Joanna is measuring how the bees respond (number emerging and behavior) to different perfumes. The response of the bees changes based on the type of perfume (independent variable). The bees are the subjects, the type of perfume is the independent variable, and conducting tests on the same - day with similar weather is a control.

Answer:

The response of the bees
