Answer:
b. the laboratory setting may not be a good representation of the real-world setting
Explanation:
The laboratory setting is different from the real world settings due to the real world settings having uncontrolled variables and conditions. Whereas the laboratory setting have controlled variables and conditions in which experiments could be performed under. The controlled or uncontrolled conditions could either influence the experiments positively or negatively.
 
        
             
        
        
        
Answer and Explanation:
Because the DNA sequence determines a protein's amino acid sequence, a gene shared by two closely related organisms should have similar, or even identical, amino acid sequences. That's because closely related species most likely diverged from one another fairly recently in the evolutionary span. Thus, they haven't had as much time to accumulate random mutations in their genetic codes.
