Answer:
The answers are:
a. dependent
b. independent
c. test
d. control
Explanation:
In scientific research, investigations are done to study whether certain factors change while changing others, and the following terms are associated with scientific research:
a. dependent variable: These are factors or outcomes that are being investigated in a research experiment, and they are not under the direct control of the researcher. They are factors that vary as a result of other changes made in the process. In our example, the heart rate and blood pressure are proposed to vary with the type of film watched hence these factors are dependent variables.
b. independent variable: Independent variables are variables that are under the direct manipulation of the researcher, and the predetermined variation of these variables cause certain effects on the dependent variables. In our example, the type of film is the independent variable, because the researcher has complete control over the type of film watched.
c. Test group: These are the group of participants/individuals in research, who will potentially be affected by the change in the dependent variable to cause an effect that deviates from the normal. In our example, the group that views the violent film is the test group, because there is a tendency that they might have altered heart rate and blood pressure as a result of the type of film viewed.
d. control group: The control group is the group of individuals whose effects at the end of the experiments will serve as baseline effects, to serve as a means of measuring the magnitude of variation in the test group. These groups serve to eliminate any other effects that might cause similar changes as the factor being investigated in all test participants.
Answer:
The only correct statement is D) Included in the category of resources called land
Explanation:
Land is a natural resource, whether it is use for agriculture, for conservation purposes, for hunting game, or for appropriation and exploitation of other resources.
All the other statements are wrong:
- A is wrong because some natural resources have value in themselves. For example, coal can be transformed to produce other things, or be extracted, and use in its pure form to produce energy.
- B is wrong because most natural resources are scarce: oil is scarce, natural gas is scarce, and even land itself is scarce. The planet Earth does not have unlimited dimensions.
- C is objectively wrong because most natural resources are exclusionary and have to be paid for. Oil has to be paid for, same thing for coal, crops grown in land, and so on. Some people might believe that natural resources are free and unlmited, but that would be a misconception.
