God must be the creator of the universe. 3 views Christians can faithfully hold: Old-Earth Creationism, Young-Earth Creationism, Theistic Evolution. What do we use in order to determine evolutionary relationships?. Fossil Record. Anatomical Evidence. Molecular Evidence. Embryological Evidence. Evidence for Evolution. Fossil Record. Evidence for Evolution. 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. Liz Cirulli. Assistant Research Professor. Duke Center for Applied Genomics and Precision Medicine (CAGPM). 4/27/15. Advantages to studying healthy variation. Most “healthy” traits not studied genetically at all. SOL A8. by Robert Lotze, Moody Middle School. Direct Variation.

Early scientists proposed ideas about evolution. . Evolution is the biological change process by which descendants come to differ from their ancestors.. A species is a group of organisms that can reproduce and have fertile offspring.. Sexual and asexual reproduction. Reproduction. advantages/disadvantages. Sexual. Asexual. Needs two parents.. Only one parent needed (quicker).. Produces variation in the offspring.. Identical offspring (no variation).. By exploring the characteristics offspring inherit when living things reproduce, I can distinguish between inherited and non-inherited characteristics.. SCN 2-14b. Learning intentions.
