Answer:
All the puppies have black hair because albino alleles are found in two different genes.  
If we let the letters A and B represent the two different pigmentation genes, the one of the dogs is AAbb, and the other is aaBB. 
Their offspring are AaBb and so there are not albinos because they have one dominant copy of each gene.

The Great Barrier Reef, located off of Australia’s eastern coast, is the largest coral reef ecosystem in the world. The reef covers an area over 300,000 square kilometers and includes a wide range of ocean depth, and it contains such biodiversity as to make it one of the most complex ecosystems on Earth. Much like any other ecosystem on Earth, the Great Barrier Reef relies on biotic and abiotic components to keep it functional and stable.
        
             
        
        
        
That would be catalysts.
Catalysts accelerate (speed up) chemical reactions without damaging itself. They do this by decreasing the activation energy of a chemical reaction.
Enzymes are a type of catalysts.
