Question

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, Marc Jacobs, Vera Wang, and the
last is 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 (came) 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.

Answer 1

Hypothesis: Exposure to certain perfumes will cause bees to exhibit agitated behavior and leave the hive.

Experimental Group: Bees exposed to perfumes (Ralph Lauren, Armani, Marc Jacobs, Vera Wang, and odorless liquid).

Control Group: Bees exposed to an odorless liquid (baseline for comparison).

Independent Variable: Types of perfumes (Ralph Lauren, Armani, Marc Jacobs, Vera Wang, and odorless liquid).

Dependent Variable: Total number of bees emerging from the hive and their observed behavior.

Control: Bees exposed to an odorless liquid, providing a baseline comparison for the effects of other perfumes.

Step-by-step explanation:

In this experiment, Joanna's hypothesis suggests that certain perfumes will cause bees to exhibit agitated behavior and leave the hive. The experimental group consists of bees exposed to different perfumes (Ralph Lauren, Armani, Marc Jacobs, Vera Wang, and an odorless liquid), while the control group involves bees exposed to the odorless liquid, serving as a baseline for comparison.

The independent variable is the types of perfumes used in the experiment, and the dependent variable is the total number of bees emerging from the hive and their observed behavior. The control is the group of bees exposed to the odorless liquid, helping assess the specific effects of each perfume by providing a baseline of the bees' typical behavior.
