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.

"The growing human population" a. will require an increase in forests and a decrease in agricultural land. b. is best addressed

storchak [24]

Answer:

C. requires the restoration of ecosystems better designed to serve the needs of humans

Explanation:

For a very long time, the survival of plants and animals has been dependent on each other. The plant depended on animals for oxygen and the animals depended on plants for carbon dị oxide.

In recent times, this balance has been altered as humans (higher animals) have started engaging in activities that hurt the ecosystem such as Bush burning, deforestation and other agricultural practices.

In view of this, there is an urgent need for the restoration of ecosystems that suit human needs. This can be done by planting of more trees, reduction in industrial activities that involves emission of harmful gases and wastes into the air, land and water.

what types of data would a meteorologist need to collect to demonstrate the presence of a cyclone in a specific region?

nevsk [136]

Answer:

Surface temperature and lower air pressure.

Explanation:

Surface temperature and lower air pressure are the types of data would a meteorologist need to collect in order to demonstrate the presence of a cyclone in a specific region. For the formation of cyclone, warm and moist air is required so surface temperature and lower air pressure are the data that gives information that the cyclone is present in a particular area or not.
