Answer:
C. Hydrogen bonds
Explanation:
Anticodon refers to the set of three nucleotides present in tRNA. The anticodon is complementary to the codon of mRNA. The nucleotide bases of anticodon and mRNA codons are paired by hydrogen bonds. 
Here, the adenine of anticodon makes the hydrogen bond with the uracil base of codon while the guanine base of anticodon forms the hydrogen bond with the cytosine base of the codon. 
There is a specific tRNA with an anticodon complementary to the mRNA codon for each amino acid. For example, the tRNA for phenylalanine has an anticodon 3' AAG 5' and binds to the complementary mRNA codon base via hydrogen bonds. 
 
        
             
        
        
        
Answer: A. Above 
Explanation:
Scientists believe that in order for humans to see things, the brain has to make certain assumptions which are done based on previous scenes that it has interpreted before because the eyes do not provide it with complete data. . 
One of those assumptions is that light comes from above which is why the shape of a picture can change depending on the lighting in it.
