1 A team of scientists prepares to study the flow of a river through a desert canyon for the next 10 years. The scientists think that the water is contributing to weathering and erosion of the canyon. What kind of data should the scientists collect as evidence to support their explanation?
A
Measure the water levels to see if less water can make the same changes in the canyon.
B
Record the measurements of distinct parts of the canyon to see if those areas change over the years.
C
Measure the temperature of the water to see if the water temperature becomes slightly warmer or cooler.
D
Take samples of the water that is flowing into the canyon. Test the samples in a lab to see whether the water and particles that make it up change over the allotted time.

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
