Positive impacts of genetic engineering:
•	New products are created such as food with higher nutrition values, drugs that are more effective and safer
•	Disease prevention (“correcting” the genetic mutation, or removing disease-causing gene)
Negative impacts of genetic engineering:
•	irreversible side effects, for example resistance of bacteria or introduction of viruses in human cells
•	abusing like change specific traits that are not connected with diseases, create human outcomes that are ethically questionable.

Answer:
Zebra mussels feed on phytoplankton, which zooplankton need as a food source.
Explanation:
The population of zooplankton in Lake Erie and the Hudson River declined due to the arrival of zebra mussels because Zebra mussels feed on phytoplankton, which is the main source food of zooplankton. So due to limited or scarcity of food in the environment, the zooplankton die due to hunger that leads to the decrease of population of zooplankton in that environment.
 
        
             
        
        
        
Answer:
A. It has lost one electron
Explanation:
Since the H has been replaced by a +, this means that the Hydrogen is now a positive ion. For this to happen, it would have to lose an electron.
Gaining one would make it <em>negative</em>, and protons cannot be gained or lost under normal circumstances.
