Anaerobically (in absence of oxygen), yeast cells may obtain energy by fermentation, resulting in the production of ATP, CO2 AND ETHANOL. This is called ethanol fermentation or alcoholic fermentation where sugars such as glucose, fructose, and sucrose is converted into cellular energy (ATP), producing ethanol and carbon dioxide as by products.
Human height is one of the traits that belong to traits that cannot easily be placed in discrete phenotypic classes (there is not only tall and short people, there is continuous variation of height between them). Such traits are usually controlled by more than one gene (polygenic traits).
On the other hand, a Mendelian trait is controlled by a single locus.
Answer:
Population growth is based on four fundamental factors: birth rate, death rate, immigration, and emigration.
Hi, the answer to this question would be an Molecular Clock. A molecular clock is a technique used by researchers that uses mutation rates in DNA to estimate the length of time that two species have been evolving independtly. Hope this helped :)
