BSC 1010C - Lab midterm exam study guide

-Test covers the following labs:  1. Scientific Method;   2. Atoms, Chemical Bonds and pH;  3. Microscope;  4. The Cell;  5. Diffusion 1;  6. Diffusion 2
-Anything that I wrote on the board may appear on the exam
-Know all the terms from the Lab Print-outs that I said you needed to know
-Understand the concepts of each of the lab activities
-Be able to answer all Lab Packet questions

1.	Know the steps of the scientific method
2.	Understand what independent, dependent, and controlled variables are, and be able to identify them from a sentence

3.	Be able to calculate pH and hydrogen ion concentration [H^+]:  i.e. converting from pH to [H^+] in decimal and scientific notation
4.	From the periodic table, be able to determine atomic number, number of electrons, and mass number for a given element
5.	Know how to draw the electron dot formula for a particular molecule
6.	Understand the relationship between protons and electrons with regard to ions (i.e. Ca^++ means that this calcium atom has lost two electrons)
7.	Know the methods (paper vs. liquid) for determining pH, and the names and functions of the pH indicators (phenolphthalein and bromthymol blue)

8.	Know the name and function of all the parts of the compound microscope
9.	Be able to calculate cell size (you need to memorize the formula):  cell size = diameter of the FOV/number of cells that fit across the diameter of the FOV.  You should be able to convert mm to µm (1 mm = 1000 µm).
10.	Be able to calculate total magnification for a particular objective lens

11.	Be able to identify the various specimens from the “Cell” lab (see my website “cell lab specimens”), and know the attached information, i.e. What kingdom or group do they belong to?  How do they obtain food?  How do they move?  What is their shape?  Etc.

12.	Know the name and function of an osmometer
13.	What was the purpose of the agar?
14.	Know the concepts of diffusion, osmosis and tonicity (i.e. hypertonic, hypotonic, isotonic)
15.	Understand molecular weight and its significance in diffusion
16.	Understand how diffusion is affected in a solid vs. liquid vs. gas
17.	How does temperature affect diffusion rate?
18.	Know the name and function of dialysis tubing; what was it simulating?
19.	Know what plasmolysis, crenation, lysis, turgid, turgor pressure are, and under what conditions they occur.
20.	Know which substances moved across the dialysis tubing membrane and why.
