a) Pyruvate is a three-carbon molecule, so two molecules can be produced from each molecule of glucose. In total, from 4 molecules of glucose that enter glycolysis, there will be produced eight molecules of pyruvate.
b) PA becomes Lactic Acid instead of Acetyl CoA in anaerobic respiration (that is in auscense of oxygen), particularly when the cell carries out lactic acid fermentation, which is what can happen in the mitochondria of muscle cells when faced with a very demanding stimulus.
<span>The question is providing us with the following scenario:The frog population in the Amazon basin varied. Every 500 years, there was a mutational change leading to speciation. In between, the population remained the same with no observable changes. This pattern of microevolution is called punctuated equilibrium. This pattern is distingushed by long periods of lack of change, followed by a sudden and often extreme change, and followed again by a period of a lack of change. </span>

Explanation:
The answer is: d. comparable in size to the heterosexual females
Simon LeVay is a neuroscientist that studies the relation of brain structure and sexual orientation. He examines the interstitial nucleus of anterior hypothalamic cells. The size of the nucleus in homosexual is found to be similar to women while the heterosexual male is much larger. The result doesn't enough to say that sexual orientation is genetic. This proves that there is the dimorphic nucleus in different sexual orientation.
