Match the statements with the correct element Photosynthesis and cellular respiration cycle carbon through living things and the atmosphere.
Cycle nutrients between living and nonliving parts of Earth
Other bacteria change ammonia (NH ) into nitrates and nitrites (nitrification)
Fertilizers with nitrogen help plants grow but runoff causes eutrophication in nearby water bodies
Human activity causes disruptions to the cycles.
Organic molecules
Burning fossil fuels releases carbon dioxide back to the atmosphere
Fossil fuels are ancient carbon stores
Animals respire carbon dioxide, which plants uptake.
Plants can use nitrates for nucleic acids and proteins
Maintain overall health of Earth
Decomposers return organic matter to the soil through ammonification

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
