Biology 3
Final Examination Review

The topics for this exam are the hormones and human reproduction through the end of the course.

Read and answer these questions after you have studied the for the examination. Use the self-test/evaluation exercises in the book as suggeted in the syllabus.  If you have studied the material sufficiently you should know the answers. Simply knowing the answers to these specific questions will not result in a good examination grade - you need to know the material and have a good understanding of how systems work.

* What is a biological community?
* What is population carrying capacity?
* Contast the growth pattern of populations growing with unlimited resources, limited resources that are not renewable and renewable resources?
* How do the pre-reproductive, reproductive and post-reproductive populations differ in population pyramids in N. Europe, Asia and Mexico?
* How great an effect does delaying the age of first pregnancy havea on population growth?
