Luisa is studying how light affects photosynthesis in an aquatic plant. She places a piece of the plant in a test tube and holds it near a light. Then she measures the number of oxygen bubbles produced by the plant. She moves the light farther away from the plant and repeats the experiment. The graph shows Luisa’s results. © 2017 Measured Progress. All rights reserved.

Describe the inputs and outputs in the model. b. Explain how increasing the amount of light will affect one output of this model. Support your explanation with data from the graph.

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
