Motion in One Dimension

In this chapter, you will learn why it is important to identify a reference frame in order to clearly describe motion. For now, the motion you describe will be one-dimensional. Within this context, you will learn the difference between distance and displacement as well as the difference between speed and velocity. Then you will look at some graphing and problem-solving techniques.

Natural Selection

Outcomes:

  • Determine which mutations are favored by the selection agents of predators and food variety and which mutations are neutral.
  • Describe which traits change the survivability of an organism in different environments.
  • Experiment with environments which produce a stable population of bunnies, a population that dies out, and a population that takes over the world.
  • Track genes through multiple generations.
  • Compare how dominant and recessive genes get passed onto offspring.

Phases of meiosis II

Meiosis is a process that creates sex cells (gametes) with half the number of chromosomes of the parent cell. Meiosis has two stages: meiosis I and meiosis II. In meiosis I, homologous chromosomes pair up and exchange genetic material (crossing over). In meiosis II, sister chromatids separate, creating four haploid cells.
