Murchison tells us that the Tasmanian Devil could go extinct in the wild in 20-30 years. Conduct a short web search about the Tasmanian ecosystem. What did you find? How might the extinction of Tasmanian Devils impact the ecosystem? List your sources below.

just finished the test, the answer is d, greg is the least cost-effective because he charges the most for the project

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.

the answer u all are looking for is 4000000000000000000000 million years.
