Use the scenario to answer the following question. Four scientists observed an area of land that had been cleared of all trees a
nd bushes to make space for a power line. Each scientist had a different argument about the impact clearing this area of land might have on the bird population living in the ecosystem. Which scientist’s argument demonstrates how the ecosystem will MOST LIKELY be impacted? A. Scientist 4: The rate of erosion will decrease causing less food and shelter to be available to the birds. B. Scientist 1: The natural enemies of birds will be eliminated causing less food and shelter to be available to the birds. C. Scientist 2: Weather conditions may change causing less food and shelter to be available to the birds. D. Scientist 3: The population of trees in the environment will decrease causing less food and shelter to be available to the birds.

CO2: 9.48/44 = 0.215 mmol
H2O: 3.87/18 = 0.215 mmol
mass of C = 0.215 * 12 = 2.58 mg
mass of H = 0.215 * 2 * 1 = 0.43 mg
mass of O in ethylbutyrate = 4.17 - 2.58 - 0.43 = 1.11 mg
So C/O = 2.58/1.11 ≈ 3 </span>
:The combination of the two galaxies then forms what appears to be an elliptical galaxy as the arms begin to disappear. The merger of gasses creates new stars, and the new shape becomes more elliptical, globular, or sometimes irregular.
