Human Organs Anatomy | Physiology
If we were to “break apart” the human body at the microscopic level, then the cell would constitute its most basic unit. Here are some of the important organs' anatomy. Need help with the Physiology Assignment? Visit globalassignmenthelp.com.au

All Sorts of Mutations: Changes in the Genetic Code - Lesson
Four boxes illustrate normal DNA and three small-scale mutation examples. 1) A normal DNA sequence (TAT, CAT, CCT, AAG, GTA) and the resultant proteins (Tyr, His, Pro, Lys, Val), 2) the same normal DNA sequence with one base substituted for another (CCT > CGT) and the new resultant protein (Arg), 3) the same normal DNA sequence with a base inserted and the new resultant protein, 4) the same normal DNA sequence with a base deleted and the new resultant protein.

Independent vs. Dependent Variable Activity
This activity can help students learn the difference between independent and dependent variables. Terms included are: Independent Variable, Dependent Variable, and Controlled Variable. There are matching cards and a control to allow students to self-check. The control is shaded. Also included are two activity sheets with answer keys. (Keys Not Shown)
Natural Selection
Charles Darwin and Alfred Russel Wallace's theory explains how evolution occurs. Individuals naturally vary in traits in a population. With limited resources, competition exists in which those better adapted - with beneficial traits suited to the environment - are more likely to obtain resources, survive, reproduce, and pass traits to offspring over successive generations. This natural selection of advantageous traits leads species to evolve over time.
