Outcomes:
How homologous chromosomes separate into two sets. Prophase I, metaphase I, anaphase I, and telophase I.
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.
This video explains how pie charts can be used to display data in a more 'user-friendly' way.
This video explains how to plot straight line graphs.
Outcomes:
Skeletons support and protect our bodies. Bugs have exoskeletons outside their bodies, while humans have endoskeletons inside. Our bones are in axial (skull, ribcage, spine) and appendicular (arms, legs) groups. Bone marrow makes blood cells; more specifically, red marrow makes blood and yellow marrow stores fat.
