Paul's father and paternal grandfather both contracted but survived prostate cancer with treatment. which answer best explains what this means for paul? paul should know he has a higher risk of prostate cancer and take preventative steps.
paul should not worry about this history as both survived the cancer. paul should have his prostate removed as soon as possible. paul should live a healthy lifestyle and not worry about cancer at all.

The correct answer would be Paul should know he has a higher risk of prostate cancer and take preventative steps.

Explanation:

Paul's father and paternal grandfather both had prostate cancer. So this well established that paul is at high risk of prostate cancer. However, his father and grandfather both survived, even though they contracted but survived so removing the prostate can not be logical. He should be taking preventative steps.

Thus, the correct answer would be the first statement.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
