If you are conducting a study on the health of people who have been exposed vs not exposed, the method you should use to obtain data would be an observational study because it involves the pre-existing condition of the subjects.
The answer is non-living elements and living species in a specific local environment, like water, hope this helped you.
Are the pythons a new species?
How can the python population be controlled?
How quickly are pythons reproducing in the Everglades?
<span>How are the pythons affecting other animal populations?
Among the choices, the question least likely to be asked is ARE THE PYTHONS A NEW SPECIES?
It may be asked but the other three questions are more important. This is because we need to know the effect of the growing python population has on the existence of other animals in the Florida Everglades.
Pythons are hunters. Uncontrolled population growth will result to the decrease of the population of other animals because they are the prey of the pythons. Therefore, rate of reproduction and observation regarding their immediate effect to their environment are of utmost importance compared to whether pythons are new species or not.
