Because of this, the estuaries have a mixture of saline water and fresh water. They are also shallow and warm. The sunlight penetrates to their bottom, and they are rich in nutrients. This results in the estuaries to offer several different living conditions, so there are lot of different species living in them.
The correct answer is option 2- Study the lionfish in their natural habitat in the Pacific Ocean.
As mentioned in the question that lionfish is considered to be highly dangerous due to their fierce and veracious life style. In order to know more about the characteristics and impact of lionfish in order to develop potential solutions to the issue is to:
- Capture lionfish and study their spine in lab
- Study their life style in their natural habitat
This will help us to improvise ways that could help us protect other fishes from lionfish and also help us to develop a safe environment for the other marine animals.

Answer:
a: True
Explanation:
Riboswitches are regulatory segments of mRNA which are capable of controlling/regulating gene expression simply by binding to small molecules. They are divided into two parts;
- The aptamer is the part that directly binds to small molecules
- The expression platform is the part that changes structure in response to binding of aptamer to small molecules. This is the part that primarily controls gene expression by turning on/off relevant genes.
<em>The correct option is a, true.</em>
