Question

1. Oil spills happen in our oceans. Some oils contain volatile organic compounds; these compounds make the oil denser. What large-scale impacts could this kind of oil spill have on the ocean environment?

a. Oil is natural and doesn't have an overall negative impact on the ocean environment.
b. Oil that is denser will sink and have a negative impact on the ocean environment.
c. Oil that is denser will float on the ocean's surface and will have a negative impact on the environment.
d. Oil will impact only select species and not have a large-scale impact on the environment.



2. Imagine a net fishery for a medium sized fish like flounder that takes a large amount of unintended catch in the form of small crustaceans and fish that must be thrown back into the sea (usually dead). You are the fishery scientist who set catch limits for this particular fishery. You did your research and believe that the limits you set are sustainable, but the fisherman tell you they are catching smaller and fewer fish. What would you tell them you think the most likely problem and is and how to address it?

a. The problem is likely global warming, and the only way to solve it will be to address global warming.
b. The problem is likely that your research is outdated and you need to collect new data, set and establish new limits.
c. The problem is likely the increasing level of decaying shrimp and small fish in the area, and could be addressed if the fisherman found a new way to dispose of the unintended catch.
d. The problem is likely the large amount of bycatch is reducing food availability for the flounder, and could be addressed by designing new nets.



3. What application of biotechnology seeks to make a positive impact on human health by searching the marine environment for novel compounds, such as new drugs?

Biochemical engineering
Biomimicry
Bioprospecting
Environmental biotechnology

Answer 1

1) Option c

2) Option d

3) Bioprospecting

Step-by-step explanation:

1) Oil will float and obstruct sunlight which is essential for plant growth in sea too.In turn this affects the whole food chain of aquatic animals.

2)The fisherman are disturbing the food chain by the unintended catch and can design their nets to catch flounders only.
