Document Summary

Exam 1 review: know the levels of biological organization. Domain, kingdom, phylum, order, family, genus, species: gain an understanding of how organisms interact with their physical environment, review the concepts of negative and positive feedback. Negative feedback- a loop in which the response reduces the initial stimulus. Positive feedback- a loop in which the response speeds up its own production: understand how evolution is a core theme in biology. Evolution- the process of change that has transformed life on earth from its earliest beginnings to the diversity of organisms living today: be ready for questions on the theory of natural selection. f. Know the steps in the scientific method. g. h. j. k. m. n. p. q. s. t. i. l. Chapter 2: understand the relationship between the subatomic particles, know the difference between atomic mass and atomic number. Atomic mass is the combined weight of the protons and the neutrons.
