Goal: Use inverse variation and joint variation models.. Warm-up. Simplify:. Inverse Variation. 2 variables, x and y, vary inversely if:. k is called the constant of variation.. Example 1. Tell whether x and y show direct variation, inverse variation, or neither:. . Authors: Cassandra Shore, Haley Minnear, Liam McGevna, Thomas Cassar. Teacher: Robert Bolen, James Ostensen. Eastport South Manor Junior-Senior High School. Introduction. . Genetic variation is vital to every ecosystem and species because it makes them stable and prosperous. Without genetic variation one simple change to the environment could destroy a whole population. . The Process of Speciation . How Common Is Genetic Variation?. Many genes have at least two forms alleles.. All organisms have genetic variation that is “invisible” because it involves small differences in biochemical processes..

John Lennon. Julian Lennon. Parents. Direct Variation. y varies directly as x if there is a nonzero constant, k, such that . y = . kx. *k is called the constant of variation. Plug in the two values you have and solve for the missing variable. Define the term variation.. Discuss the fact that variation occurs within, as well as between, species.. Describe the differences between continuous and discontinuous variation, using examples of a range of characteristics found in plants, animals and other organisms.. Human variation: defined . Human variation refers to the fact that there are a range of possible values for each of the numerous physical characteristics of human beings.. People of the same species can have differing phenotypic traits that can be related to:. Identify. three examples of inherited characteristics, and three environmental characteristics. Explain. why sound cannot be heard in space. Suggest. some advantages and disadvantages of recycling.
