Answer:
Explanation:
The only way a recessive trait will show is if the offspring receives 2 recessive (lower case) alleles. 
If there are any upper case letters present only the dominant trait will show. 
The correct answer would be the box(es) that contain 2 lower case letters.
 
        
             
        
        
        
Answer:
tt
Explanation:
Firstly, look at the oldest female shape. It would be a circle since that is female and which circle, would be the oldest one. In line one. Since the circle is white, the gene has not been carried so it must be reccessive.
tt because it is the only allele pair that would give you the gene without obtaining that trait, meaning it is reccessive.
So it would make sense that tt is the choice.
 
        
             
        
        
        
There are three types of hormonal release control (increase or decrease production), which is stimulated by
1. specific molecules, minerals or particular nutrients ( chemical regulation)
2. other hormones (hormonal regulation)
3. input from nervous system. (neural regulation)
If the inhibition is caused by a different hormone, it would be considered hormonal regulation.  In the given example, the hormone is produced in the target organ.
However, if the inhibition is due to the accumulation of the hormone itself, then it is an example of a <em>negative feedback</em>.
        
             
        
        
        
A well-tested explanation for a set of observations or experimental results is a theory. When we're talking about theories, we're talking about a set of hypothesis about a certain topic which have been shown to work and be correct but aren't completely proven up to the point where we could say they always hold true.
