Question

jamie and the bees
jamie read that certain chemicals would cause bees to leave the hive and act in an agitated manner. she decided to investigate the response of bees to four different perfumes (charm, white diamonds, forever, and dune). she placed a saucer containing 20 ml of the first perfume 3 meters from the bee - hive. she recorded the time the first bee emerged from the hive, the total number of bees that emerged, and the observations of the bees behavior. she repeated the experiment with the three other perfumes. she was careful to have the same weather conditions (temperature, humidity, wind) during each experiment.
7 multiple choice 1 point
the independent variable of jamies experiment is
o the weather conditions.
o the type of perfume.
o the bee hive.
o the response of the bees
8 multiple choice 1 point
the distance of the perfume from the hive, the amount of the different perfumes, bee hive, and weather conditions are all examples of
o procedure.
o constants.
o dependent variable.
o the independent variable
9 multiple choice 1 point
the bees behavior and the time they emerge from the beehive in response to the perfume would be the
o dependent variable.
o independent variable.
o constant.
o procedure.

Explanation:

In an experiment, the independent variable is what the experimenter changes. Here, the type of perfume is being changed to see how bees respond. Constants are factors that are kept the same throughout the experiment, like the distance of perfume from hive, amount of perfume, bee hive, and weather conditions. The dependent variable is what is being measured or observed as a result of the change in the independent variable, which is the bees' behavior and emergence - time in response to the perfume.

Answer:

1. B. the type of perfume
2. B. constants
3. A. dependent variable
