Your challenge will be to create a Dichotomous Key for trees located around Floyd Dryden. You have five types of
leaves to categorize and organize into a key.
The first step is to identify their Scientific Names (Genus species).
• Alnus serrulata
• Picea sitchensis
• Athyrim filix-femina
Tsuga heterophylla
• Salix Alaxensis
.
Next you want to categorize them into two groups.
Then you want to continue to regroup them until each one is identified.
You may write out this assignment in your Science Notebook. If you do not have your Science Notebook available,
you may type out your key.

Awoman whose sister tested positive for a specific mutation in the brca1 gene, which increases the risk for breast and ovarian cancer, is found not to have that mutation but does have a mutation of unknown significance near the known mutation site. how should this woman be counseled? select one: a. she should be informed that her risk for breast cancer is greater than the general population but not as great as her sister’s risk. b. she should be informed that because she does not have the mutation, her risk for breast cancer is not greater than that of the general population. c. she should be informed of her gene mutation status and be presented with all the available prophylaxis options and reconstruction options. d. she should be informed that she does not have the specific mutation but that because another mutation is present she should be vigilant about screening
