									            BIOLOGY 1ST SEMESTER EXAM REVIEW
NOTE: Please understand that I have done my best to put together a Study Guide for the exam.
However, if there is something on the exam that is not on this study guide but it was covered this
semester, then it has the possibility of being on the exam. You should not be using this as your only
source of studying for the exam. It is my strong suggestion that you use your old tests to study for the
exam as well as looking through each chapter thoroughly. Anything covered this semester could be on
the exam.

Chapters covered this semester: 1 – 4, 6 – 8, and 10 – 11

Chapter 1

    Terms:

       biology                reproduction           development           organism               species

                    have to identify the experimental group, the control group, the
                    hypothesis, and draw conclusions based upon the data.

    1 graph: You will have to answer a few questions about a graph on population growth.

              factors, the effect of introducing a new predator or prey. Also be able to
              identify a limiting factor as being density-dependent or density-independent.
              Be able to determine the independent and dependent variables and then answer
              some questions about the graph.
