Please help me and no file Is it accurate to say that
having the BRCA-1 gene gives someone cancer? Explain your thinking.

On average, women with an altered BRCA1 gene have a 50 to 85 percent risk of developing breast cancer by age 70. Their risk of developing ovarian cancer is 40 to 60 percent by age 85. A woman with cancer in one breast has a higher risk of developing cancer in the other breast.

from my research i have to the conclusion that decomposers, such as fungi, bacteria and invertebrates, play a critical role in nutrient cycling and without them the earth's ecosystem may not support life as we know it. elements such as carbon, nitrogen and phosphorus exist in limited amounts on earth, although huge amounts of carbon are being released into the atmosphere from underground sources now by humans. it is still extremely important that other nutrients be retained by the process of re-use. decomposers are organisms that are able to chemically break down dead material and make these elements available for use by other organisms. without this breakdown of dead material, dead bodies would pile up. so decomposers also play a role in clean up also. without them, life might not continue as we know it and dead material would overwhelm the earth.
