There are many theories about why living thins sleep, however, scientists are still unsure about what the answer to this question may be. Some say it is because of its restorative powers - after a good night's sleep, you feel rested, and all your brain and bodily functions work better than when you are exhausted. During sleep, some rejuvenating and growth hormones are created, which again adds to our advantage. You also relieve stress that has accumulated during the day. These are some of the reasons why we have to sleep.

Answer:

The options to this question is incomplete, the correct options are:

A) the citric acid cycle.

B) oxidative phosphorylation.

C) glycolysis.

D) the citric acid cycle and oxidative phosphorylation

The answer is D

Explanation:

Cellular respiration is an important metabolic process carried out by the cells of living organisms including human cells. Aerobic cellular respiration involves three main stages viz: Glycolysis, Kreb's cycle, and Oxidative phosphorylation. These three processes occur to bring about the breakdown of glucose to synthesize ATP.

Glycolysis occurs in the cytoplasm while Kreb's cycle and Oxidative phosphorylation both occurs in the matrix and intracellular membrane of the Mitochondrion respectively. Hence, a drug that causes holes in both mitochondrial membranes will affect both Kreb's cycle and Oxidative phosphorylation.

How did the gold that we are able to mine become part of Earth?

Montano1993 [528]

Answer:

Where to Find Gold

According to estimates, all of the gold ever mined in the history of humanity amounts to about 152,000 metric tons. This sounds like a lot, but it is only about enough to fill up 60 trailers. Scientists believe that there is still eight times more gold in and under the oceans than has ever been mined close to the planet’s surface. Like the gold that is probably floating in the Earth’s molten core, most of this supply of the precious metal is inaccessible or simply too expensive to mine. Interestingly, gold has been discovered on all of Earth’s continents except for Antarctica. Of course, it is possible that even that continent holds some gold under all of the ice.
