The correct answer is:

C)Populations have no effect on their environment.

Explanation:

Ecology is the department of biology which studies the interactions between organisms and their environment. Objects of study involve interactions of organisms with each other and with abiotic elements of their environment.

Incomplete question. The remaining part of the question read;

Words in the left column:

Yes
No
Observational
Manipulative

1. A physiologist incubates eggs in the lab at a range of temperatures to see what temperatures produce males and what temperatures produce females.

2. A biologist predicts that shade might influence ground temperature, and therefore turtle sex ratios. He records the sex ratio of turtle hatchlings in shaded and unshaded regions

3. An ecologist predicts turtles grow larger when no predators are around. She places turtles in an experimental pond system where half the ponds have predators and half the ponds have had the predators removed.

4. A climatologist predicts that concentration of CO2 in a city will be negatively correlated with the amount of wind in that city. He collects data and looks at the amount of CO2 in a city as a function of the wind speed in the city.

5. A sociologist conducts a survey in Hawaii to describe people's attitudes about global climate change.

6. A scientist determines the average wind speed, and variation in the amount of wind, in a number of locations to see which locations would be most suitable for wind turbines

Answer/Explanation:

1. Hypothesis-driven? Yes!

Observational or Manipulative? Observational.

We can make this conclusion here that the physiologists' research is hypothesis-driven since we are told he wanted to "see what temperatures produce males and what temperatures produce females." In other words, he wanted to know whether the temperature used in incubators can influence the sex of an egg by means of observation.

2. Hypothesis-driven? Yes!

Observational or Manipulative? Observation.

3. Hypothesis-driven? Yes!

Observational or Manipulative? Manipulative.

We can make the conclusion that is the ecologist used the manipulative method in her research since she decided to place the turtles in two different types of ponds; one where half the ponds have predators while in the other the pond the predators have been removed. In other words, she manipulated the independent variables.

4. Hypothesis-driven? Yes!

Observational or Manipulative? Observational.

Note, the use of the word, "predicts" in most instances underscores the tone of hypothesis-driven research, hence we can say Yes! And remember, we are told the researcher "collects data", meaning he is merely observing differences that occur naturally.

5. Hypothesis-driven? No!

Observational or Manipulative? Observational.

6. Hypothesis-driven? No!

Observational or Manipulative? Observational.

Experimentation (or the experiments the scientist was doing for 10 years) could be wrong or done in an inappropriate way. The only way to know if the information is valid is by checking the way the experimentation (data) was done as well as making sure to check all other factors
