In 2004, tests were performed on the San Carlos Reservoir in Arizona to determine levels and distributions of some toxic metals.
Cores of sediment were sampled and tested, and the scientists found that there were two time periods represented in the sediment by larger levels of copper than is recommended in sediment quality guidelines. What scientific investigation might these results lead the scientists to next?
an investigation on how copper affects aquatic life in the reservoir
Explanation:
It was observed that there were two time periods represented in the sediment by larger levels of copper than is recommended in sediment quality guidelines at the San Carlos Reservoir in Arizona
The next things that will be on their mind is to investigate on how copper affects aquatic life in the reservoir
At dawn the squid prepares to hide in the sand for the day and it ejects about 95% of the bacteria from the light organ in order to reduce or stop the growth of bacteria population in the squid. This will prevent the bacteria population from reaching a level too high for the squid to support.
