Answer:
Explanation:
The DNA double helix acts as a template for its own duplication. Because the nucleotide A will successfully pair only with T, and G only with C, each strand of DNA can serve as a template to specify the sequence of nucleotides in its complementary strand (more.
 
        
             
        
        
        
A trilobite. Trilobites became extinct about 250 million years ago while a ammonite became extinct around the same time as dinosaurs(65 million years ago). You wouldn't find a human skull or a dinosaur footprint
        
             
        
        
        
Answer:
The virus lacks strcutures to replicate genetic material.
Explanation:
They can replicate it, but don't have structures to do it without the help of a cell. They USE the cell to replicate it but cannot do it themself.
Virus lacks genetic matrial? It has DNA.
Protective outer shell? Ptotection has nothing to do with it.
Movement? They cannot duplicate without cells.
 
        
             
        
        
        
Answer:
I believe the first one would be incomplete dominance, the second would be multiple alleles, and the third would be codominance. 
Explanation:
The first one would be incomplete dominance because the child has a blend of the man's straight hair and the woman's curly hair, but neither of two hair types are completely dominant (if that makes sense). 
The second one would be multiple alleles because, well, there are multiple alleles listed (more straightforward than the other two).
And the third one would be codominance because the traits of red color and white color are equally dominant.
