Answer:
As the graph is not provided, lets try to answer the question generally.
Explanation:
Human activities are known to be threatful and harm biodiversity in several ways.
Humans activities like deforestation results in many species from losing their homes. These species are not able to survive and hence become extinct.
Human activities such as fragmentation cause the genetic diversity to become lowered for organisms of a species. As a result, a disaster such as a disease results in killing all the organisms of a species present in a community.
Yes it is therefore the answer is true
Answer:
what you change vs what you are testing
Explanation:
The independent variable is the variable that you change. For example, if we were growing plants and wanted to see if more sun made them grow higher, you would change the amount of sun that each plant is exposed to.
The dependent variable is what you measure. This depends on the independent variable. So, in our plant experiment, the height of the plant is the dependent variable.
Control. The control is what stays the same. So in our plant experiment, the amount of water, type of plant, type of soil, and all of these things would stay the same to insure that the results are equal.
You affect the independent variable and the control and you test the dependent variable.
