Eutrophication occurs due to excessive use of these compounds, which can lead to having dead zones in bodies of water. 
Dead zones refers to areas with decreased levels of oxygen in the bodies of water caused by eutrophication and other factors. These affect the marine life negatively as fishes are also dependent on oxygen. 
Eutrophication is defined as the presence of excess minerals in the water, which causes dense growth of plants and leads to depletion of oxygen that make the animals in the water to die.

Answer:
Replicate itself into the cell host
Explanation:
Visus is made from a protein capsule and inside a fragment of RNA. Sometimes they also have some feet of filament to get attached to the cellular membrane.
Once attached, the virus injects its RNA into the cytoplasm and travels to the nucleus and insert this fragment of RNA into the cell DNA and start making copies of itself.
When the cell is full of virus, the membrane breaks and releases all the new virus to the neighbor cells, and the process starts again.
 
        
             
        
        
        
  If the mutation occurs during meiosis, the mutation will be incorporated into a gamete. If that gamete is the one that eventually fuses with another gamete (i.e. if it's the sperm that fertilizes the egg), that mutation will be passed on to the offspring. As all the offspring's cells are the result of the first two gametes, all the organism's cells will have that mutation. Obviously this can have dire consequences for the offspring, if the mutation is harmful.
