Answer:
See the answer below
Explanation:
<em>Hemophilia typically affects more males than females because the disorder is </em><em>X-linked </em><em>and </em><em>recessive</em><em>. </em>
<u>Females have two X chromosomes (XX) while males only have one X and one Y chromosome (XY). The two X chromosomes in females are capable of carrying alleles while the Y chromosome in males is hypothesized not able to carry alleles. </u>
Consequently, the two X chromosomes in females will both need to carry the recessive allele of hemophilia in order for any female to be affected for hemophilia while the males only need their single X chromosome to carry the recessive allele in order to be affected. 
In order words, the presence of a single recessive allele is not enough for a female to be affected while it is more than enough for a male to be affected. Hence, more males are affected b hemophilia disorder than females. 
 
        
                    
             
        
        
        
The given statement is true.  
Some of the health science sites may restrict employees from wearing perfumes or other fragrances because the chemicals in the fragrances can stimulate reactions ranging from headaches to palpitations of heart in some of the individuals who are sensitive to them, making it tough for them to work efficiently.  
With time, the individuals getting exposed to the chemicals present in the fragrances become more sensitized to them to the point that they can no longer tolerate any more exposure. This can initiate breathing issues, nausea, sneezing, disorientation, and in extreme situations, they can even go into shock.
