Answer:
Genes.
Explanation:
Genes are present on DNA that are inherited from parents to their offspring. Genes may be defined as the segment of DNA that ultimately form a particular protein product. 
The particular trait of an organism is determined by the specific combination of the inherited genes. The genes are nearly same in all the human beings and there mutation can cause observable phenotype traits.
Thus, the correct answer is option (2).
 
        
             
        
        
        
The answer would be C because the car is can be refueled just like a normal car but is mostly powered by a electrical battery/motor
 
        
                    
             
        
        
        
Answer:
Transcription and RNA processing (splicing)
Explanation:
Although Howard is almost right, the DNA sequence does not precisely relate to the protein sequence. First of all, the DNA is transcribed to an primary mRNA molecule. Bur before the mRNA is ready to be translated into an amino acid sequence, it must be processed into a mature mRNA.
This includes adding a 3' poly A tail, and a 5' cap, and importantly for this question, splicing.
Splicing is the removal of non protein coding intermediate sequences called introns from the protein coding regions (exons) of a primary mRNA. This means that lots of the DNA sequence is not dictated by the final protein, as many of the intervening sequences have been removed by splicing.
 
        
             
        
        
        
Answer;
C) ATP
Explanation;
-Photosynthesis can be divided into two parts: the light-dependent reactions and the light-independent reactions (also referred to as the "dark" reactions). 
-The two products of the light-dependent reactions of photosystem are ATP and NADPH.  The movement of high energy electrons releases the free energy that is needed to produce these molecules.  The ATP and NADPH are used in the light-independent reactions to make sugar.
-The light-independent reactions, or dark reactions, of photosynthesis are chemical reactions that convert carbon dioxide and other compounds into glucose. These reactions occur in the stroma, the fluid-filled area of a chloroplast outside the thylakoid membranes.
