6/3 - Lesson
Using what you have learned in the last 2 weeks answer the following 3 questions. They are due by 6/4 and are worth 15 points. 1. What is the most likely cause of the decline of the Ocean Edge sea otter population? Cite specific evidence. 2. How does natural selection work; or what are the requirements and mechanism? 3. Given your answers to 1 & 2; can se expect the sea otter population to adapt and survive the threat? Explain

The following table may help you answer the first question:

death rate || adults || 86 || 17 || 20% || 8% ||
 * || population || deaths || death rate || stable population
 * pups || 55 || 30 || 55% || 52% ||
 * juves || 38 || 16 || 42% || 40% ||
 * sub-
 * adults || 121 || 9 || 7% || 7% ||

5/12 Natural Selection
We are beginning a study of natural selection. Follow the link below as a guide: Mechanisms of Evolution We will be following through this website - to understand how this all works

4/1 Ecology:
Ecology is the study of the environment and relationships. It studies how each part of the environment is is connected to and affects each other part. Think about how you are connected to your environment. List 5 SPECIFIC interactions between you and the environment. When you have that list, watch the video below:

TED talk: Jane Pointer

Upon finishing the video, check your original list and make any corrections to anything that you wrote. Then add 5 more SPECIFIC interactions between you and the environment.

4/2 Biogeochemical cycles:




4/4 NOTES:
Reservoir - storage "container" reservoirs can function as both a sink and source Sink - a place where stuff is added Source - a place where stuff is taken from

Metamorphism - (meta = change) (morph = form) change one kind of rock into another kind of rock with heat and pressure Outgassing - release of gases from volcanoes Decay - breaking down of biomass (organic material) Combustion - burning Respiration - oxygen "burning" glucose in our cells to produce energy for life Photosynthesis - plants making food (glucose) using sunlight for energy 6CO2 + 6H2O --> C6H12O6 + 6O2

The small purple arrows represent the movement of carbon from one reservoir to another. Identify the processes and label as many of them as you can. You can download the picture and then add text boxes to make the labels.

As we have been looking at protein folding, view these videos to help you understand how it works:

media type="file" key="Simulation of millisecond protein folding- NTL9 (from Folding@home).mp4" width="363" height="363" media type="file" key="hemoglobin.mp4" width="300" height="300" Hemoglobin is a protein with a quaternary structure. This means that after the polypeptide chains fold into their tertiary structures, multiple chains come together to form the functional protein. For hemoglobin, their are 4 polypeptide chains -- two alpha and two beta chains. media type="file" key="Protein Folding.mp4" width="363" height="363"

Upon finishing your lab report, please visit the Chem4Kids website again: http://www.chem4kids.com/files/bio_intro.html Pay special attention to the 4 groups of biochemicals: Their names, examples, structures, building blocks, role or function in living systems. Also, start a vocabulary list. There is TONS of vocabulary associated with biochemistry. :)

download the biochem documents

If you have your new laptop, please create a folder for science on the desktop. Keep your notes and handouts in this folder. They can be sorted by date, and you can retrieve what you are looking for, easily.
