Lesson 17

1) Dredging is digging up mud/sand and transporting it out of the channel. Dredging needs to be done in Ventura Marina because of the shoaling problem. With this problem there is sediment rising under water where the ships are parked. If the sediment gets too high, the boats will get stuck and not be able to get in and out of the marina.

2) The problem with Devil’s Slide in San Mateo County is that it has a lock of landslides and closures. A solution they used to stop with the destruction of the landslides is building a bridge.

Lesson 18

1) The way I would define life is that we all started out as small molecules. We all eventually started growing our own set of DNA. Of course none of us were the same so we had different DNA. We are also made out of a bunch of atoms that replicate to make new life forms.

2) Transcription is the process of DNA being read and a messenger RNA is made. Translation is the messenger being read and the protein built. Both transcription and translation is the process needed in order to create a new life form.

3) Evolution

4) RNA was the molecule that did it all. Everything started with those molecules. Nothing consisted more than RNA molecules. Like the chicken and the egg example, the RNA could act as either the chicken or the egg and replicate itself. It evolved in the DNA protein world.
