Why are cells so small? Explain (in 1 to 3 sentences), and include in your explanation: surface area and why surface area is important.   

Part 1:  Type the correct name for each structure in the cell.  Please include the letter and the name.  For example:  X = Telomeres (this isn’t one of the answers for this cell, it is just an example.)  Also, spelling counts. Part 2:  What type of eukaryotic cell is this cell?    Hints: A is the entire large “ball.”  C includes the “dots” and the “squiggly” thing with the “dots.”   Cell #1.png

What are “relaxed” (loosely coiled) chromosomes called?

If a cell is placed in a hypertonic solution, the cell will lose water and appear

For ALL of the following scenarios, provide the following:  A.  Identify all solutions (in the beaker and in the dialysis tubing “bag”) in relation to the other.  (Hypotonic, Hypertonic, and/or Isotonic)  B.  Which direction will the water molecules move (assume only the water can move through the “bag” but the solutes can’t)?   SCENARIO I – 70% salt (30% water) solution is in a “bag” inside a beaker with a 10% salt (90% water) solution in the beaker.   SCENARIO II – 30% salt (70% water) solution is in a “bag” inside a beaker with a 90% salt (10% water) solution in the beaker.   SCENARIO III – 48% salt (52% water) solution is in a “bag” inside a beaker with a 48% salt (52% water) solution in the beaker.  This is a general image of the scenarios. This is to help you “picture it.”  The different “dots” represent the different molecules.  This is a general image.  It isn’t specific to any of the scenarios, but it can be used to help think through the scenarios described above.   Beaker with Dialysis Tubing.png

List two (2) of the four (4) structures that are the same between prokaryotic and eukaryotic cells.   Provide two (2) structures that both types of cells have.  

solar energy + carbon dioxide + water  →   carbohydrate + oxygen This equation shows which cellular process?

If a cell is placed in a hypotonic solution, the cell will

Which type of microscopes provides a much greater ability to distinguish two points as separate points (resolution)?

Exam #2 Topics Include:  Cell Theory, Cell Types, Cell Structures, and Cell Membranes / Materials Transport Due Date/Time: 11:59 PM Wednesday OCTOBER 15, 2025. Point Value = 100 points Maximum Time Limit = 75 Minutes (in one sitting) Must be taken in one 75-minute sitting/session. Honorlock is required to take this exam. Remember to comply with the identification requirements, and show your photo ID, please. Acceptable forms of ID include: CCAC Student ID, Driver’s License, or other Government-Issued ID.  Spelling counts. IF YOU NEED TO USE SCRAP PAPER, YOU MUST SHOW THE BLANK PAPER TO THE CAMERA FIRST, THEN WRITE WHAT YOU NEED TO, THEN SHOW THE WRITTEN-ON PAPER TO THE CAMERA. Be sure that you type all your answers and any work into the exam, too, please. IF YOU NEED TO USE A CALCULATOR, IT MUST BE A REGULAR CALCULATOR (HAND-HELD OR ON SCREEN). PHONES AREN’T PERMITTED. YOU MUST SHOW THE CALCULATOR TO THE CAMERA IF IT IS HAND-HELD.  Reminder:  If students do not submit exams by the scheduled due date and time, a grade penalty will be applied. If the exam is submitted within 24 hours of the original due date/time (that means 1 minute late up to 24 hours late), then a 25% grade deduction to the exam grade will be applied. If the exam is submitted 24 hours to 48 hours after the original due date/time, then a 30% grade deduction to the exam grade will be applied. Exams will NOT be accepted after 48 hours after the scheduled due date and time, and a zero (0) will be the grade recorded for that exam.  This information is in the Course Outline. REMINDERS: Exams, tests, and quizzes are closed books, closed notes, closed slides, closed assignments, and taken individually. No additional devices allowed other than the one (1) being used for the exam/test/quiz. Only the test/exam/quiz screen should be open. A simple, basic calculator can be used (not phones). No other windows, websites, programs are permitted.  “Cheating = The act or attempted act of deception by which a student misrepresents that he/she has mastered information on an academic exercise that, in fact, has not been mastered.”If you are found to be cheating on an exam or assignment at the very least, you will receive a grade of “0” for that exam or assignment. This may also lead to a failing grade in the course and disciplinary action by the college and the Dean of Academic Affairs. Please do not diminish your learning experience by cheating.
