Biology Vocabulary: 1. Immigration: influx of individuals into an area 2. Emigration: movement of individuals out an area. 3. Logistic growth: (shown with an S-shaped curve) population growth that levels off at carrying capacity. 4. Exponential growth: (shown as J-shaped curve) geometric increase of a population as it grows into an ideal unlimited environment. 5. Niche: the sum total of a species use of the abiotic and biotic resources in its environment 6. Symbiosis: an ecological relationship

Syllabus—Biology 100 Dr. B. Pozos Welcome! Course Philosophy Biology 100 is an exciting and important course for non-science majors that applies general concepts in Biology towards every day living. Part of my philosophy behind this course is governed by the dual realizations that 1) healthcare delivery is very confusing to patients who do not understand biological terminology and processes and 2) that for many of you‚ Biology 100 will be your first and last science course. Eventually all

Shalacia Gilmore Fall 2012 BIO 1107 Natural Selection Lab INTRODUCTION In the 1850s‚ two scientists by the name of Charles Darwin and Alfred Russell Wallace composed the theory of evolution by natural selection. (1) Darwin characterized several claims needed for natural selection to happen‚ including heritable variation within the population‚ and the presence of more individuals than the environment can support. They also discovered that certain environments favored certain traits. These
