You have been teaching for many years and think that sitting in the front of the classroom leads to greater learning than sitting in the back of the classroom, based on your observations. Explain how you would test this, using good experimental design, as we covered in the class, for both an experimental and an observational study.  Keep it simple and in your own words! A) Design a simple EXPERIMENTAL study to examine this.  Explain what you would do and what you would measure. B) Design a simple OBSERVATIONAL study to examine this.  Explain what you would do and what you would measure.

You are studying eukaryotic cells to determine what problems arise when particular organelles or structures are not functioning correctly.   In this cell, most processes are working correctly but the cell is not maintaining its shape, or moving correctly, and the movement of some materials in the cell seems to be blocked.   Given that information, which organelle is MOST likely NOT functioning correctly in these cells?  

You are studying eukaryotic cells to determine what problems arise when particular organelles are not functioning correctly.  In this cell, cell growth and production of proteins have all slowed down as has the movement of some materials across the plasma membrane.  The root cause seems to be insufficient ATP in the cell. Given that information, which organelle is MOST likely NOT functioning correctly in these cells?  

You are studying eukaryotic cells to determine what problems arise when particular organelles are not functioning correctly.   You have a group of cells that show a build-up of a variety of molecules that would usually be degraded (broken down) into smaller components within the cell and then eliminated.  Given that information, which organelle is MOST likely NOT functioning correctly in these cells?  

Look at the atom shown below.  Based on the information contained in the image, choose the statement below that is TRUE. Key: Circles with X = electrons; Dark circles = protons; Open circles = neutrons

Molecules vary in size and charge.  Which combination below would be most likely to pass through the phospholipid bilayer via simple diffusion?  

Match the organelles given with their functions/descriptions

Match each description to the correct molecule type. Some molecules may be used more than once; some may not be used at all.  

Look at the atom shown below.  Based on the information contained in the image, choose the statement below that is TRUE. Key to diagram: Circles with dash = electrons; dark circles = neutrons; circles with + = protons

Look at the atom shown below.  Based on the information contained in the image, choose the statement below that is FALSE. Key: Circles with X = electrons; Dark circles = neutrons; Open circles = protons
