Nellie has a family history similar to Lorene Alhern's. Nellie's mother died at an early age from breast cancer, as did her mother's sister. Nellie is not yet 35 but has started having annual mammograms. She has also been tested or BRCA1 and BRCA2 mutations. She has a BRCA2 mutation and is considering prophylactic surgery. Her younger sister, Anne, doesn't want to know the results of Nellie's genetic testing because if Nellie has a BRCA2 mutation, then there is a chance that Anne could have inherited the same mutation from their mother. Required:
a. Does Nellie or Nellie's doctor have an obligation to tell Anne about the test results?
b. What about Nellie's older brother? Should he be told? There are personal and medical benefits and risks to consider here.

The answer is going to be a because ik that i’m right

Hunting in the darksome fish rely on senses beyond sight. in the darkness of the marianas trench, a fish called the rattail has an extremely sensitive sense of smell. the fish uses scent, rather than sight, to steer toward food. once it's near food, the rattail uses a special organ on the bottom of its chin to guide itself by feel.marine snowone staple of the deep sea diet is "marine snow," flakes of organic, edible substances that sink down from the upper ocean. animals at the ocean's bottom find sustenance in everything from the bodies of dead creatures to fecal matter. marine snow is diverse enough to support numerous species. for instance, several species of snails and worms feed exclusively on deceased whales.microorganismsthe deep sea is an intricate ecosystem, and even the ocean floor itself plays a part. hydrothermal vents are cracks in the sea floor where erupting magma mixes with ocean water to produce plumes of hot, sulfur-rich chemicals. some microbes can use these chemicals for energy, sustaining their existence and that of the animals who depend on their roles in the deep sea food chain.
