Answer:

Independent variable is that which we change or manipulate.

Explanation:

By changing the independent variable, there is a corresponding change in the dependant variable which we intend to measure.

Answer:

The dependant variable is the one you measure. The dependant variable depends on how you change the independent variable.

Explanation: For example we want to observe speed of a car change with respect to time.

Here, time is the independent variable as it has its own pace regardless of the car. However, at different instances of time , the car has different speeds. Thus, the speed of the car is the dependant variable as it depends on time.

Answer:

The answer is a negative feedback loop. Negative feedback is used to counteract an effect and achieve back a homeostatic balance. An example of a negative feedback loop is in thermoregulation.
