Since the 1970’s, the Earth has been warming. Can this be due to natural, increased solar output? Why or why not?
Margarita [4]
No.

The Sun can influence the Earth’s climate, but it isn’t responsible for the warming trend we’ve seen over the past few decades. We know subtle changes in the Earth’s orbit around the Sun are responsible for the comings and goings of the ice ages. But the warming we’ve seen over the last few decades is too rapid to be linked to changes in Earth’s orbit, and too large to be caused by solar activity.

the corrective actions made by the bionic pancreas on a regular basis in response to changing blood sugar levels are similar to
Art [367]

The correct answer is: a feedback mechanism.

The bionic pancreas is bio-engineered device used for the regulation of blood sugar levels in order to maintain body homeostasis. The bionic pancreas includes a sensor that monitors blood sugar levels and sends a signal to a separate device that will then release the appropriate hormone into the bloodstream to return blood sugar levels back to normal. This device is very functional because of its ability to dose insulin and glucagon based on continuous sugar blood measurements.
