Answer:
The investigation of the Hudson River is an example of scientific inquiry because it develops testable questions such as this; <em>How might a zebra mussel invasion affect the Hudson River ecosystem?</em>
All the other elements of scientific inquiry were applied.
Explanation:
Developing and using models: Scientists developed ways to check for changes in the river using the data available to them.
• Planning and carrying out investigations: Several scientific institutes have planned and carried out investigations to determine reasons for the return of the Zebra mussels.
• Analyzing and interpreting data: Graphs are plotted to evaluate to draw a relationship between the zooplankton and the Zebra mussels.
• Using mathematics and computer technology
: Mathematical measurements were done to analyze the sizes of the Zebra mussels.
• Constructing explanations
: Explanations were proposed as to why the Zebra mussels were not eating up them. It made sense to them that more Zebra mussels would result in more Zooplanktons
• Engaging in argument from evidence
: They could argue from the evidence that blue cobras were eating up the Zebra mussels
• Obtaining, evaluating, and communicating information: After scientists have obtained their information, they endeavor to communicate them by publishing them in scientific papers and journals.
Collecting and analyzing complex biological data
Sedimentary rock: a solution made by depositions of earths natural resources where mineral or organic particles are formed. It is also the main source for scientific knowledge to be recovered of earths history and is an important source of natural resources that appear for instance coal, fossil fuels.
Answer:
The correct option is D. Cow dung would have piled up in Australia.
Explanation:
The native beetles of Australia did not feed on the dung from the non-native cattle. As the cattle were imported from another country, the native beetles did not recognize the texture of the dung and hence, did not feed on them. As a result, cow dung started to pile up. To get rid of the dung, the best possible solution was to import beetles from a different country which recognized the texture of the dung and could feed on it.
