Blizzard Tuesday
(February 2, 2011)
Homework:
- Read Chapter 19 no strategy needed
- Finish lab 38
- Due Flow map on 19.3
Notes:
We took notes on Tuesday and here are my notes:
- Homologous structures-the organisms don't have to use the structure the same way but the structure looks very similar. One way I remember what Homologous structure is the start to homologous-homo which means similar or same
- Analogous structures-same function but different structure ,but if put in the same environment natural selection would probably make the structure the same. My hint for this is Analogous structure reminds me of the word analogies and an analogy is like an Analogous structure.
- Vestigial structures-structures that exist in an organisms but serve no purpose.
- Comparative Embryology- a comparison between embryos. My clue to remember this is Embryology contains embryo and that what it involves.
- Molecular biology-finds similarities in amino acids and DNA and RNA
On Tuesday we went over the notes above and then we started the lab that we have for homework.
Our next scribe will be David
