Lionfish have become an invasive species since their introduction into the atlantic ocean, where they have few natural predators due to their venomous spines and quick reproduction. they feed voraciously on native reef fish and mollusks, negatively impacting coral reef biodiversity. how can scientists further investigate the characteristics and impact of lionfish in order to develop potential solutions to this issue? capture lionfish and study their spines in a laboratory study the lionfish in their natural habitat in the pacific ocean study maps of lionfish sightings prior to 1995 use a remotely operated underwater vehicle (rov) to capture lionfish

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: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.
