Answer:
In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. Oxygen is released as a byproduct. In cellular respiration, oxygen is used to break down glucose, releasing chemical energy and heat in the process
Explanation:
product, whereas cellular respiration uses oxygen as a reactant to release energy from food
 
        
             
        
        
        
Gases A, B, and D all have the same average molecular kinetic energy, since they are at 12°C.

Carbohydrate is a group of compounds that is comprised of very simple units of sugar called the monosaccharide. From the prefix "mono", this means that the simplest unit is composed only of one block of sugar. Monosaccharide examples include: glucose, galactose, and fructose. From the given lists above, the one that does not match perfectly is the fourth pair. Glycogen is a multibranched polysaccharide. 
ANSWER: glycogen - monosaccharide
        
             
        
        
        
<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>
        
                    
             
        
        
        
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.
