Answer:
The Richter scale is a numerical scale for expressing the magnitude of an earthquake on the basis of seismograph oscillations. The more destructive earthquakes typically have magnitudes between about 5.5 and 8.9; the scale is logarithmic and a difference of one represents an approximate thirtyfold difference in magnitude.
Explanation:
The differences between true experiments and quasi-experiments is that in a true experiment, participants are randomly assigned to either the treatment or the control group, whereas they are not assigned randomly in a quasi-experiment. Quasi experiments are empirical interventional study used to estimate the casual impact of an intervention on its target population without random assignment.
Answer:
C
Explanation:
Producers are also known as autotrophs, which they make their own food. Producers capture sunlight energy and use it to convert CO2 (carbon dioxide) and H2O (water) into O2 (oxygen) and C6H12O6 (glucose) for other organisms to use. This process is called photosynthesis.
