I can’t help you with the first two questions, as I do not have a reference, but I can help you with the last two. Cystic fibrosis is a recessive trait. It is caused when specific sections of both copies of chromosome 8 are deleted, which in other words mean that it is not a sex-linked disorder because it isn’t inherited from the mother and father of the offspring.
No, all mutations are not bad. Only a small amount of mutations cause genetic disorder. Some in fact are good mutations. There is actually one mutation that is found roughly in 10% of Europeans which affects the CCR5 protein and it prevents HIV from entering the cell! 
 
        
             
        
        
        
<span>The answer would be: as the bicarbonate ion in the plasma after first entering the red blood cells
Carbon dioxide will be changed into bicarbonate ion that released into the plasma. That is why the level of carbon dioxide will influence the pH of the blood. The process will produce hydrogen ion so higher carbon dioxide will result in acidosis. It is important to keep the carbon dioxide level at a certain point to prevent blood pH stable</span>

Answer:
Meiosis
Explanation:
In a process of meiosis a sing cell divides twice to produce four daughter cells which contains half the amount of. genetic information These cells are sex cells. These four daughter cells consists of half the number of chromosomes of the parent so they are haploid. This is the reason in maple tree the chromosome decreased from 52 to 26.
