jenn and rico are studying bumblebees for class and have decided that their hypothesis is, bumblebees in rural environments are healthier than those in urban environments.
they must now begin investigating.
based on their hypothesis, select the statement that best explains the type of investigation jenn and rico should perform.
this investigation should be a 3-d model in the form of a bee. the behavior can only be viewed if the bee itself is large enough to see the internal organs.
this investigation should be a descriptive investigation. the variables are controlled by nature. the students will observe the bees in multiple settings and record data.
this investigation should be a computer simulation. the students are unable to observe the bees first-hand and must recreate the environments themselves.
this investigation should be an experimental investigation. the students need to be able to create the setting for the bees and create the variables identified in their hypothesis.

Explanation:

To determine the correct investigation type, we analyze each option:

• The 3 - D model option is irrelevant as it focuses on viewing internal organs, not testing the hypothesis about bee health in different environments.
• A descriptive investigation is appropriate here. Jenn and Rico are comparing bumblebees in natural rural and urban environments. In a descriptive investigation, variables (like the environment and bee health) are controlled by nature, and researchers observe and record data from existing settings.
• The computer simulation option is incorrect because there's no indication they can't observe bees firsthand.
• An experimental investigation would require creating the settings and variables, but they are studying bees in their natural rural and urban environments, so they can't create these settings.

Answer:

This investigation should be a descriptive investigation. The variables are controlled by nature. The students will observe the bees in multiple settings and record data.
