Fertilization to Implantation
Once the egg is ovulated from the ovary it enters into the oviduct (fallopian
tube). It is in the oviduct that the egg may be fertilized by a sperm. After
fertilization, the cell is now called a zygote. The zygote u
This is a formal definition of the menstrual cycle. The menstrual cycle is
controlled by the hormones of the female reproductive system and is closely
tied to the ovarian cycle.
Hormonal activity will be discussed throughout the course. This is
Two-group experimental design
One common type of experiment used to test hypotheses uses the two-group
experimental design. In this type of experiment, there is an experimental group
in which the subjects are exposed to a variable that is being
Heart disease is the number one killer of women in our country (six times
higher than breast cancer). Based on correlative studies, researchers
hypothesized that HRT would reduce the incidence of heart disease in women
who used it.

Upon reaching the penis, the nervous system message will cause a release of cyclic
GMP. Cyclic GMP causes a relaxation of muscles in the walls of blood vessels of
the penis. When the muscles relax, more blood can flow into the penis, and the
The top protein is a normal hemoglobin protein. The one below it is a
sickle-cell hemoglobin molecule. Note that only one amino acid has been changed.
The change in the amino acid is due to a mutation in the DNA that coded for it. On

DNA is the central figure in all aspects of human biology including developmental
processes, cloning, diseases, medical research and human individualism. To
understand all of the issues, requires an understanding of DNA.
DNA is sometimes called
Cell differentiation involves genetic changes within the DNA of the cells. DNA
directs changes in the chromosomes which switches off much of the DNA. The cell
then only uses a portion of the DNA and begins to take on a specialized function.
The second portion of the lecture will involve infertility and in vitro fertilization.
Students will learn
about several causes of infertility and understand how in vitro fertilization can help
overcome some of

Welcome to Contemporary Issues in Biology
This course is designed to inform non-science majors about biology through
the use of contemporary issues found in the popular press. Rather than teach
biology in a traditional approach as is currently u
