OSMOSIS is the diffusion of water through a selectively permeable membrane. Water will generally move quite freely through the cell membrane by diffusion. Osmotic movement of water occurs when the solute (non-penetrating) concentrations differ between the opposing sides of the cell membrane. A difference in solute (non-penetrating) concentrations means there is a difference in water concentrations and water will move from the region of higher concentration to a region of lower concentration.

WOU Biology 100 Series Graphs Overview
Making a graph is one of the easiest ways to get an idea of the patterns in your data.
Graphing is a fairly straightforward process, but there are a few things to keep in mind.
1. Type of graph. You should think carefully about the kind of data you have before you
decide what type of graph to produce. See Figure 1.
a. Line graphs are useful to show how a factor changes over time or in some other
gradual continuous increment (like temperature or ambient light).
b. Bar graphs are useful to show a total change or overall difference between
different discrete variables (like types of organisms or specific experimental
treatments).
Figure 1. Types of Graphs. The graph on the left is a line graph. The graph on the right is a bar graph.
2. Variables
a. The independent variable is the variable that you change or manipulate in the
experiment. This variable is usually placed along the x (horizontal) axis. In the
case of an experiment where you are observing something that changes over
time, time serves as an independent variable and is always listed on the x-axis. If,
in addition to time, there is a second independent variable (e.g. observing what
happens to two different treatments over time) this variable is usually graphed by
drawing multiple lines on the graph. See Figure 2.
b. The dependent variable is the response or what happens in response to the
independent variable. Typically, this variable is what you counted or measured
during the experiment. This variable is placed along the y (vertical) axis.
3. Titles and Labeling.
a. Every graph needs a concise and descriptive title that explains what phenomenon
the graph is attempting to visualize. If you averaged data from several different lab
groups before graphing, you should note in the title that your graph depicts
averaged data (like in the bar graph in Figure 1).
b. Each axis should be labeled, and the label should include the units in which the
data was recorded. Without units, your graph is meaningless.

Table 1, below, shows an example of data collected during an experiment. The same data is

collected in the visual graph compared to the data table, as long as the graph is titled

This document will serve as your guide, sending you to the relevant lab activities and introductory
information found in the eSciences lab manual (pages for this unit are 68 - 81), or in the online replication of
the eScience lab manual uploaded to Blackboard for those of you who prefer to follow along online.
NOTE: I recommend that you read from this lab guide & report document first, going to the
eSciences manual materials only as directed. Students previously using the lab manual
have found that the additional background information provided in this document and the
step-by-step guidance through the eSciences lab materials to be beneficial.
BACKGROUND INFORMATION: DIFFUSION
Diffusion is the net movement of a solute away from an area of high concentration towards an area of lower
concentration. If you have ever watched tea diffusing from a tea bag, you are familiar with the process of
diffusion. You have watched the brown molecules leaving the tea bag until eventually the tea become
uniformly brown. This is sometimes referred to as solute molecules moving down their concentration
gradient.
Notice that I said that it is NET movement of a solute. This means that like all molecules in liquid and gas
phases, solute molecules move randomly in all directions. There is no driving force for sending a solute
molecule down its concentration gradient other than there is no way to prevent the random movement of
molecules. Eventually, the solute molecules will become totally randomized in their distribution throughout
the solvent.
What does diffusion have to do with biology? Virtually all movements of molecules into and out of, and
around the interior of the cell relies on diffusion of solutes. The removal of waste products from the cell
relies on the random movement of these molecules from the inside of the cell to the outside of the cell.
Similarly, the uptake of vital nutrients relies on their diffusion from the outside to the inside of the cell. The
circulatory system speeds these processes up by sweeping nutrients into the vicinity of cells and sweeping
away waste products from the cells to be excreted elsewhere from the body.
Note that the diffusion of oxygen (a vital nutrient) and carbon dioxide (an ever-present waste product of
cellular respiration) are a part of this story. Diffusion is critical in the process of providing nutrients and
oxygen circulating in the bloodstream to cells. A cell must be close to a capillary, within100 microns from a
capillary, in order for these metabolites to diffuse to the cell quickly enough. If it is farther than that from the
cell, it will not receive the ...

During the course of this activity, you will be learning and practicing micropipetting, polymerase chain reaction (PCR), and DNA gel electrophoresis. Each topic below provides, or refers you to, background information on the technique prior to the hands-on activity where you will learn the technique.
Learning Objectives:
1. Be able to properly select and utilize micropipettes for the manipulation of small volumes of liquid.
2. Be able to explain how PCR amplifies DNA and be able to perform a PCR protocol.
3. Understand how gel electrophoresis is able to separate DNA fragments, be able to pour an agarose gel, load samples, and interpret results.
Lab notebooks:
Look over the notebook guidelines posted in the general Lab Materials content folder. Begin this lab by writing a summary of the lab’s objectives.
I. Micropipettes
Pre-lab Introduction:
A micropipette is a kind of fancy eyedropper – one that comes in many different models and volume ranges. But while an eyedropper dispenses drops, micropipettes transfer microliters of fluid. Recall that ‘micro-’ is a prefix in the metric system which means “one-millionth” of the base unit (in this case, a liter, “L”). It may be easier for you to picture one milliliter (mL or ml) of water. If you mentally subdivide that milliliter of water into 1000 tiny equal-sized volumes, each volume is one microliter (abbreviated μL or μl). Watch the 2 pipetting videos posted in the lab 2 content folder (https://www.youtube.com/watch?v=p-OPOYbeZP0 & https://www.youtube.com/watch?v=NgosWmRjjAo) , then continue from here.
Micropipette Anatomy:
1. Examine the figures to the right to familiarize yourself with the anatomy of a micropipette.
2. Micropipette plungers have 3 positions:
a. Rest position- no pressure on plunger
b. First stop- position that will draw desired volume into tip
c. Second stop- position that will fully expel a sample from the tip
3. Pipette tips are pressed.
Dissolution is a process in which a solid substance solubilizes in a given solvent.
Method for dissolution are-
1. Beaker methods
2. Open flow through compartment system
3.Dialysis concept
This document discusses in vitro dissolution testing methods. It defines dissolution as the process by which a solid substance solubilizes in a solvent, and dissolution rate as the amount of drug substance that goes into solution per unit time under standardized conditions. It then describes 7 common apparatus used for in vitro dissolution testing according to pharmacopeial standards, including the rotating basket, paddle, reciprocating cylinder, flow through cell, paddle over disk, rotating cylinder, and reciprocating disk methods. Each apparatus has distinct advantages and disadvantages for testing different drug products and dosage forms.
The document discusses invitro dissolution testing. It begins with an introduction to dissolution and BCS classification. It then covers theories of dissolution like the diffusion layer model. It describes various invitro dissolution test models including non-sink methods like the USP rotating basket and paddle apparatus and sink methods like the flow through column method. Finally, it discusses factors that can affect dissolution testing and provides a conclusion.
This document provides instructions for calibrating common volumetric glassware used in analytical chemistry including volumetric flasks, pipettes, and burets. It explains that glassware must be calibrated to avoid systematic errors in measurements and outlines the general calibration procedure which involves weighing the amount of water contained or delivered, converting this to a volume using the density of water, and correcting to the standard temperature of 20°C. Tips for proper use of each type of glassware are also provided to reduce random errors.

Micromeritics refers to the science and technology of small particles. It deals with particle size, size distribution, shape, surface area, and pore size. Knowledge of these properties is important in pharmacy because particle size affects drug release from dosage forms and stability of suspensions, emulsions, and tablets. It also influences flow properties and uniformity of drug fill in tablets and capsules. Smaller particle sizes increase dissolution and absorption rates for some drugs. Common methods to determine particle size include sieving, sedimentation, light scattering, and electrical sensing using a Coulter Counter.
The document presents information on the development of dissolution methods. It discusses the processes involved in dissolution testing of solid oral dosage forms including that the drug must be released and dissolve in GI fluids to be absorbed. It also outlines factors that affect dissolution tests such as the apparatus, dissolution fluid, and process parameters. The document provides details on apparatus selection and types, as well as key elements of developing a dissolution method such as ensuring it is discriminatory, robust, and correlated to in vivo outcomes.

Osmosis
Definition- Process - Egg experiment
The flow of the solvent through a semipermeable membrane from pure solvent
to solution, or from a dilute solution to concentrated solution, is termed Osmosis
(Greek Osmos = to push).
The phenomenon of osmosis is the spontaneous passage of a pure solvent into a
solution separated from it by a semipermeable membrane, a membrane permeable
to the solvent but not to the solute.
• As time passes, the volume of the solution increases and that of the solvent
decreases. Eventually the liquid levels stop changing, indicating that the system has
reached equilibrium.

its walls is fitted with a long glass tube.

In vitro dissolution, Alternative Methods.pptxPrachi Pandey
In vitro dissolution and drug release testing provides important information about drug product performance. There are several methods for testing, including sink and non-sink methods as well as natural convection, forced convection, and continuous flow/through methods. Key factors in testing include the dissolution medium, apparatus used, sampling timepoints, and analytical methods for quantifying the amount of drug released over time. Dissolution and drug release profiles are important for understanding and comparing the in vivo behavior and therapeutic effectiveness of different drug product formulations.

Micromeritics refers to the science and technology of small particles. It deals with particle size, size distribution, shape, surface area, and pore size. Knowledge of these properties is important in pharmacy because particle size affects drug release from dosage forms and stability of suspensions, emulsions, and tablets. It also influences flow properties and uniformity of drug fill in tablets and capsules. Smaller particle sizes increase dissolution and absorption rates for some drugs. Common methods to determine particle size include sieving, sedimentation, light scattering, and electrical sensing using a Coulter Counter.
The document presents information on the development of dissolution methods. It discusses the processes involved in dissolution testing of solid oral dosage forms including that the drug must be released and dissolve in GI fluids to be absorbed. It also outlines factors that affect dissolution tests such as the apparatus, dissolution fluid, and process parameters. The document provides details on apparatus selection and types, as well as key elements of developing a dissolution method such as ensuring it is discriminatory, robust, and correlated to in vivo outcomes. Steps involved in method development like degassing, sinkers, agitation, sampling, and cleaning are also summarized.

Osmosis
Definition- Process - Egg experiment
The flow of the solvent through a semipermeable membrane from pure solvent
to solution, or from a dilute solution to concentrated solution, is termed Osmosis
(Greek Osmos = to push).
The phenomenon of osmosis is the spontaneous passage of a pure solvent into a
solution separated from it by a semipermeable membrane, a membrane permeable
to the solvent but not to the solute.
• As time passes, the volume of the solution increases and that of the solvent
decreases. Eventually the liquid levels stop changing, indicating that the system has
reached equilibrium.
A pot with s semipermeable membrane deposited in
its walls is fitted with a long glass tube.
• It is filled with concentrated aqueous sugar solution
and immersed in distilled water.

• The osmosis of water through the membrane from
water to the sugar solution takes place.
• As a result, the solution level in the long tube rises
over a period of time. After a few days the level
attains a definite maximum value.
• This marks the stage when the hydrostatic pressure set up due to the column of sugar

Osmotic Pressure.
Osmotic pressure may be defined as the external pressure applied to the
solution in order to stop the osmosis of solvent into solution separated by a

In vitro dissolution, Alternative Methods.pptxPrachi Pandey
In vitro dissolution and drug release testing provides important information about drug product performance. There are several methods for testing, including sink and non-sink methods as well as natural convection, forced convection, and continuous flow/through methods. Key factors in testing include the dissolution medium, apparatus used, sampling timepoints, and analytical methods for quantifying the amount of drug released over time. Dissolution and drug release profiles are important for understanding and comparing the in vivo behavior and therapeutic effectiveness of different drug product formulations.

For the following question(s): A school counselor tests the level of depression in fourth graders in a particular class of 20 students. The counselor wants to know whether the kind of students in this class differs from that of fourth graders in general at her school. On the test, a score of 10 indicates severe depression, while a score of 0 indicates no depression. From reports, she is able to find out about past testing. Fourth graders at her school usually score 5 on the scale, but the variation is not known. Her sample of 20 fifth graders has a mean depression score of 4.4. Use the .01 level of significance.

9. OSMOSIS is the diffusion of water through a selectively
permeable membrane. Water will generally move quite freely
through the cell membrane by diffusion. Osmotic movement of
water occurs when the solute (non-penetrating) concentrations
differ between the opposing sides of the cell membrane. A
difference in solute (non-penetrating) concentrations means
there is a difference in water concentrations and water will
move from the region of higher concentration to a region of
lower concentration.
Click Mouse Here to View Next Text on the Blackboard
11. For example, water osmotically moves into a cell when the fluid
outside the cell has more water (less solutes) than the fluid
inside the cell. In this case, as water moves into the cell, it
12. swells as the water pressure inside the cell increases.

Distilled Water
14. DIALYSIS is the separation of solutes according to their size by
diffusion through a permeable membrane. Depending upon the
molecular pore size of the membrane, solutes will either diffuse
across the membrane or be restricted by their size.
The device you will be using to collect data for the experiments
is an osmometer. This is a device used to measure osmotic
force.

about dialysis
Click Mouse Here to View Next Instructions on the Blackboard
Dialysis is the diffusion of a solute (salt, glucose, etc.) across a
selectively permeable membrane. In this case the solute
molecules always move from the stronger concentration
(hypertonic) to the weaker (hypotonic).
44. Dialysis involves the movement of some, but not all, of the
dissolved substances in a solution. The substance that moves
has small molecules, so these can pass through the pores in the
membrane, but other substances, with larger molecules, cannot
escape.
45. The green molecules are small enough to fit through the pores
of the semi permeable membrane while the red molecules are
too large.
Click Mouse Here to View Next Instructions on the Blackboard
*
46. Click Mouse Here to View Next Instructions on the Blackboard
This process occurs normally in the kidney. Substances with
small molecules, such as salts, glucose and urea, continuously
pass out of the blood through a membrane under pressure, but
useful substances are later reabsorbed. Waste substances are
then excreted as urine.
Kidney
*
47. In this exercise you will measure diffusion of small molecules
through dialysis tubing, an example of a semi permeable
membrane. The movement of a solute through a semi permeable
membrane is called dialysis. The size of the minute pores in the
dialysis tubing determines which substance can pass through the
membrane.
48. The light blue object here represents a section of dialysis
tubing. The red spheres represent molecules which are able to
move through the dialysis membrane, while the blue spheres
represent molecules too large to move out of the dialysis
membrane solution.
