What are some ways to prevent the spread of zebra mussels?.
Zebra mussels are the invasive species of the molluscan phylum and are freshwater organisms. Proper washing and cleaning of the boats and vessels should be done.
What is the effect of the Zebra mussels?Zebra mussels are invasive and non-native species that spreads very quickly in the water bodies. There increased population affects the native species of the water bodies as it affects the food resources.
Some of the ways by which the spreading of the mussels can be prevented are by washing the boats and the vessels before reentering them in other water bodies. Another way is to dispose of the water containing baits and catches on lands instead of emptying them into other water sources.
Therefore, the spreading of zebra mussels can be prevented.

One of the revolutions in molecular biology in the past decade was
the use of Green Fluorescent Protein (GFP) to make it easier to visually identify specific
components inside living cells. GFP can be seen under a microscope because it fluoresces,
or glows, when certain types of light shine upon it. Scientists can instruct a cell to link GFP
to a specific protein as it is being created and then follow the protein under a microscope.
Explain why this might be useful.
GFP can be useful because has been widely used as a biomarker and can be obtained from gene manipulation, using recombinant Escherichia coli as a microorganism for protein expression.
what does GFP allow?GFP allowed intracellular structures to be observed without the need to employ synthetic dyes or fluorescent antibodies (which may require the use of detergents for cell permeabilization, which can also harm them).
With this information, we can conclude that GFP can be useful because it has been widely used as a biomarker and can be obtained from gene manipulation, using recombinant Escherichia coli as a microorganism for protein expression.
