* Hormone A causes hormone B to be produced. Hormone B increases the production of hormone C. As hormone C increases its abundance,it causes less hormone A to be produced. This is an example of negative feedback.
* The production of testosterone in human males is controlled by negative feedback loop

Which of the following statements about red giant stars are true? (Select all that apply.) Red giant stars are less luminous than main sequence stars of the same temperature. Red giant stars tend to be more luminous than main sequence stars of the same temperatures because they are larger in size.
