Answer:
A) The gene flow between hatchery-reared and wild populations is leading to a decline in fitness of wild populations.
Explanation:
<u>we have relative fitness at its greatest in trouts whose parents are wild x wild. crossing the wild with hatchery reared causes a decrease in the fitness of the troutgene flow is the exchange of genes between two different breeds. the wild is a greatly diverse breed and it is highly adaptive. while the hatchery reared is less adaptive.when these two breed less fit alleles will then be transferred to the wild</u>
therefore option a answers the question
 
        
             
        
        
        
How they’re classified:
There are two main classifications of minerals major minerals are minerals your body needs in relatively large quantities and trace minerals are minerals your body needs in relatively small quantities major minerals include sodium,potassium, chloride, calcium, phosphorus, magnesium, and sulfur 
What they share nutritionally:
They’re solid, inorganic, naturally occurring, and have a definite chemical composition and crystalline structure
        
             
        
        
        
Answer:
Basically in simple terms, a process in which capable animals can adapt and live longer to their environment than to others. Like a light colored mice on dark rock wouldn't survive unlike dark colored mice
