The PER and TIM proteins accumulate during the day until they cause sleepiness. What prevents them from continuing to accumulate at night?

a. Metabolic rates increase at night, so proteins are digested faster than they can be synthesized.
b. The high levels of melatonin present at night react with the proteins to disable them.
c. The proteins are unstable at the lower body temperatures that are typical at night.
d. When the proteins reach a high level, they turn off the genes that produce them.

Answer to Question 2

Chalmers (2007) proposed that we regard consciousness as a fundamental property of matter. A fundamental property is one that cannot be reduced to something else. For example, mass and electrical charge are fundamental properties. Maybe consciousness is like that.

But it's an unsatisfying answer. First, consciousness isn't like other fundamental properties. Matter has mass all the time, and protons and electrons have charge all the time. So far as we can tell, consciousness occurs only in certain parts of certain kinds of nervous systems, just some of the time not when you are in a dreamless sleep, and not when you are in a coma. Besides, it's unsatisfying to call anything a fundamental property, even mass or charge. To say that mass is a fundamental property doesn't mean that there is no reason. It means that we have given up on finding a reason. And, in fact, contemporary physicists have not given up. They are trying to explain mass and charge in terms of the Higgs boson and other elements of the universe. To say that consciousness is a fundamental property would mean that we have given up on explaining it.
