Answer:
What effect do human activities have on natural resources?
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.
this is somewhat similar
 
        
                    
             
        
        
        
1. 50, 10grams passed through barrier to equalize
2. 50, same as 1
3. 40, can’t pass through barrier
4. 60, same as 3
5. water level rises in side2, lowers in side 1 because 10 grams of liquid passed through barrier
 
        
        
        
Survival can possibly be one
        
             
        
        
        
Answer:
1) If mRNA is UAU-GGG, What are the two amino acids
In mRNA UAU it is leucine amino acid is present which is used for biosynthesis of proteins. Leucine is an alpha-amino acid, and it also contains an alpha- groups, an alpha – carboxylic acid group. And GGG is the glycine it is the building block of protein. Being not an essential amino acid, it can also be induced from other chemicals.  
2)If DNA is TAT-CGC, what are the two amino acids
In DNA TAT is leucine amino acid is present which is used for biosynthesis of proteins. Leucine is an alpha-amino acid, and it also contains an alpha- groups, an alpha – carboxylic acid group. CGC have the proline amino acid in it, it is an proteinogenic amino acid, used biosynthesis of the proteins. 
3)If tRNA is GAC - AGU, what are the two amino acids
In tRNA GAC the amino acid is aspartic acid, being side chain also enzyme and proteins in the body. AGU is the serine amino acid.
