8 molecules would result, since 2^3 = 8. Each time PCR is performed, the orginal number of molcules double.
When stem cells grown on hard, rigid surface, then they became bone cells. Researchers demonstrate in Nature materials that human mesenchymal stem cells grown on a rigid substrate for some time become biased toward differentiating into bone-cell lineage, whereas cell grown on softer surfaces are just likely to eventually follow a bone or fat cell fate.
Given what we know, we can confirm that the basic idea resulting from these studies is that a creature's metabolism is related to its lifespan.
<h3 /><h3>How is metabolism related to lifespan?</h3>
From the studies done and the comparison of the lifespan of certain species in relation to their metabolic rates, scientists have noticed that <u>metabolism</u> and <u>lifespan </u>are inversely proportional. The <u>slower </u>the metabolism of an organism, the <u>longer </u>that organism can live.
Therefore, we can confirm that the basic idea is that a creature's metabolism is inversely proportional to its lifespan, meaning that the faster the metabolism, the shorter the lifespan of the creature in question.

Answer:
A. The ash would increase the albedo and decrease the global temperature
Explanation:
The volcanoes can have a big impact on the global temperature. If the volcanic eruption is big enough, and the volcanoes manages to propel very large amount of ash in the atmosphere, the whole planet will feel the effect. The ash will make a layer in the atmosphere around the planet. This layer will increase the albedo of the atmosphere, as the ash will block big portion of the sunlight. That will result in much less sunlight reaching the surface of the Earth, thus in sharp decrease in the global temperatures.
