Answer: d. the wind
Wind is not a land resource. It is the natural movement of air across the earth surface. Wind is also considered as movement of gases present in the atmosphere. The strength and direction of wind can be measured. It is a atmospheric resource. Wind produces as a result of difference in the atmospheric pressure. When a difference in atmospheric pressure exist air moves from region of high pressure to low pressure area. Wind energy is renewable source of energy can be used to produce electrical energy.
Answer:
The set of prescribed behaviors that are associated with a particular social position.
Explanation:
A role in a society is a behavior that we do as part of our position that we have in that society. There are many roles that we do on a daily basis.

Answer:
Independent: Purposely altered
Dependent: Changes with respect to the independent being altered
Controlled: Never changes
Explanation:
An independent variable is a variable in which does not rely on other pieces/variables of an experiment to assume a value. In other words, it does not change when other variables change. However, it can be changed intentionally by the scientist.
A dependent variable is a variable in which its change in value relies on other pieces/variables of an experiment to assume a value. So, if the indeoendent variable is changed, the dependent variable will change as well. The opposite is not true though - if the dependent variable changes (for whatever reason), the independent variable hasn't necessarily been changed.
A controlled variable is a variable that stays CONSTANT throughout an experiment. It is never changed, and nothing will change it. An example of a control variable is the number of participants in a study: no more participants are being added, and no participants are being removed. The number of participants remains STATIC throughout the study.
The formation of the canyon provides a physical barrier that me lead to speciation between the two populations if interbreeding is prevented. The population to the west of the canyon will probably adapt to feeding on the berries on land, and might therefore evolve traits for a terrestrial, vegetarian existence. The turtles to the east of the canyon will evolve to take advantage of the river environment, and aquatic characteristics will be further emphasised.
