S1.3 Blood flow through the heart Links to an external site.
- The blood flow information starts at about 2:00 minutes in and goes to about 6:00. With a quiz right after you can do.
S1.5 The nervous system and action potential Links to an external site.
- Check out time 1:13 in video for central nervous system vs peripheral. At 3:05 branches of the peripheral nervous system. 6:19 video of the action potential.
- Here is also a good diagram Links to an external site. that shows break down of the PNS.
S1.6 Muscle contractions thin/thick filaments Links to an external site.
- Emphasis on the sliding filament model from 4:30 to 7:00 and the role of thick and thin filaments (myosin and actin)
S2.1Intro to eukaryotic cell organelles Links to an external site.
- For TEAS the focus will be on eukaryotic cells and their organelles, and much less emphasis on bacterial prokaryotic cells.
S2.1 Mitosis vs meiosis. Links to an external site.
- Side by side comparison starts at around 2:30.
- Understand that mitosis produces 2 diploid cells that are genetically identical while meiosis produces 4 haploid cells that are each unique. Also check out this diagram Links to an external site. from Wikipedia to see the difference between homologous chromosomes/sister chromatids and sister chromosomes
S2.2 Transcription/Translation Links to an external site.
- Transcription (DNA>RNA) video starts at around 2:40 translation (RNA> protein) starts around 3:50. It is unlikely you will need the codon chart at 6:00 for TEAS test.
S2.3 Punnett squares (there are 2 videos below)
- For mono-hybrid Links to an external site. ( 1 gene crosses) The cross starts at around 3:50 in video with video before that explaining the genes in guinea pigs.
- The dihybrid Links to an external site. ( 2 gene crosses) TEAS will not ask beyond dihybrid crosses. The dihybrid cross video starts around 4:50.
- Also check out the Page on this course for common crosses
