Weighted Average Problems
The average atomic mass of an element is the weighted average of the
masses of its naturally occurring isotopes.
The isotopes of chlorine are Cl-35 and Cl-37
In nature 75 % of all Cl atoms have a mass of 35 amu (Cl-35)

Neutralization of acid rain through use of base incorporated hydrogels in plants
Topic: Land management, Water Conservation
Step 1: Global Impact
The global issue of pollution can lead to acidic rain. Acid rain is known as a mixture
of wet and dry composi
Lab Title: Modeling Diffusion and Osmosis; Observing Osmosis in Living Cell
Purpose:How does Diffusion and Osmosis Occur?
Osmosis is the movement of free water molecules from a high area of water potential to
an area of low water potential through a selec
DNA Restriction Analysis
STATEMENT OF PROBLEM
In this experiment, samples of DNA from the bacteria Lambda were cut along with EcoR1 and HindIII. A
third DNA sample is the control that was undigested, while a fourth sample was cut with an unknown

Cephalopods, are a class of mollusks which scientists classify as octopuses, squid,
cuttlefish and nautiluses. These "brainy" invertebrates have evolved suckered tentacles, cameralike eyes, color-changing skin, and c
Respiration refers to two different but related processes: one is the active acquisition of gaseous
oxygen by an organism and the other is the release of energy from organic compounds within a
cell. The latter process, a chemical oxi

Surface Area and the Rate of Diffusion into Agar (will change later)
Problem: How does the surface area of a substance relate to its volume? How does the rate of
diffusion vary with the surface area to volume ratio?

A test cross is a way to explore the genotype of an organism. Early use of the test cross
was as an experimental mating test used to determine what alleles are present in the genotype.
Usually when creating a new variety t
