What is eutrophication? what can speed it up?

This is the process by which a body of water acquires  a high concentration of  nutrients, especially phosphates and nitrates. These typically promote excessive growth of algae. As the algae die and decompose, high level of organic matter and the decomposing organisms deplete the water of oxygen, causing the death of other organisms such as fish.

Eutrophication is  a natural, slow-aging process for a water body  but human activity greatly speeds up the process  e.g. through  much use of agricultural fertilizers that contain nitrogen and phosphorous which get carried away in run off water and in to waterways.

a few examples of ethical concerns involving genetically engineering of humans include

-privacy of genetically tested people

- potential side effects

-long term effects

lysosome is this part of the cell is surrounded by a very thick outer membrane to protect the rest of the cell from its strong enzymes.
