Because the prefrontal cortex is still developing, teenagers might rely on a part of the brain called the amygdala to make decisions and solve problems more than adults do. The amygdala is associated with emotions, impulses, aggression and instinctive behaviour.

Answer:b. Amino acid sequence, hydrogen bonding between backbone groups, the overall shape of a single polypeptide, and combinations of tertiary structures.
Explanation: Primary structure is the amino acid sequence in the polypeptide chain. When the sequence is altered due to mutation it can lead to formation of entirely new amino acid sequence.
Secondary structure could be the helical structure or the Beta pleated sheet. It is form from the interaction of atom that are backbones.It is the hydrogen bond between amino Hydrogen and carboxyl oxygen atom in the backbones
Tertiary structure- Overall structure of polypeptide. It result from interaction of the R groups amino acids. It gives the shape of the polypeptide.
Quantenary- Are protein made up of multiple polypeptide chain. This chain are also called subunit. It is the combination of all tertiary structures given rise to a functional protein.
 
        
                    
             
        
        
        
Answer:
Its primary role in red blood cells is to maintain levels of red blood cells with low levels of this compound are more suceptible to oxidative damage.
Explanation:
Pentose phosphte pathway helps in the formation of reducing equivalent named NADPH.
   The so formed NADPH is used to maintain a normal cellular level of glutathione which act as antioxidant.
  As glutathione is not mantained in its normal level, it ability to reduce to adverse effect of hydrogen peroxide is cut down. 
   As a result cell is more suceptible to oxidative damage.
