Which is the best example of organisms that have been naturally selected?
KengaRu [80]
<span>Natural selection is when species learn to adapt to their environment. They could (1) differential reproduction, that is, not all organisms are able to reproduce to their fullest capacity because nature cannot simply sustain it and (2) acquire genes, that is heredity. Certain characteristics of organisms tend to survive if it continues to strive. If it survives, this trait is passed down to the next generations forgetting the other traits but only the one who could survive the environment. Therefore it is true that <span>natural selection is when ‘organisms inherit advantageous traits, and tend to reproduce more successfully than other organisms’. One best example is the extinction of other animals and some with the same species retains.</span></span>

aniked [119]

Answer:

<h2>92%</h2>

Explanation:

When glucose is converted to ethanol by yeast, one mole of glucose is converted  into two moles of ethanol and two moles of carbon dioxide,  

and this process produce two moles of ATP.  

C6H12O6 → 2 C2H5OH + 2 CO2

When glucose is converted to ethanol by yeast (as in the production of beer) 92% of the chemical energy that was originally stored in glucose still remains in the end product, ethanol, that is produced.
