It was pollution from the industrial revolution that caused tree trunks to turn from light to dark in color.
Answer: Water Quality.
Explanation:
The figure of the unhealthy ecosystem shows the industrial runoff into the water. This run off contains nitrogen and phosphorous in excess amount.
This excess nutrients leads to the growth of the algal bloom in water which in turn reduces the amount of oxygen which is easily seen in the the water.
This growth is caused due to poor water quality, and if the industrial run off will be reduced the quality of water will improve.
Answer:
In the study there was an experiment performed, with the experiment it was determined that twins who were separated at a young age, did not have a significant impact on their behavior. In the study scientists were surprised because the twins still had similar behaviors. That is because both twins inherited traits from their mom and dad. In the study I believe nature was more evident than nurture because even though the twins were separated they still had similar personalities. However, I do still believe that part of their personality will be influenced by their environment and the people they are surrounded.
In this study there were several research methods used. The psychologists used questionnaires to research how the twins traits and personalities develop. They also used observation, they observed the twins behaviors. But the patient and the observer could be influenced by what they are trying to discover, so this technique is biased. And they used case stud, the case studies would be the twins because they are the ones being observed and are the base of the experiment.
In one paragraph, describe the research methods used in this study and why you believe they were chosen. Be sure to use key terms such as cross-sectional research, longitudinal research, data collection, observation, case studies, questionnaires, and experimentation, as they apply. Your answer should include at least two of these key terms.
In one paragraph, discuss the research findings. Does the study support genetics (nature) or environment (nurture) as a stronger influence on human development? Use information from the article and the lesson to support your response.
