Answer:
Deforestation
Climate Change 
Invasive Species
Explanation:
Seventy percent of the Earth's plant and animals dwell in forests, and deforestation affects them directly. Once their habitat is lost, they are on their way to extinction.
Climate change also causes extinctions not only as a result of species intolerance to high temperature, but more commonly via a variety of related factors that alter a species’ interactions with other species. 
Invasive species invade foreign territory. They use resources that the other species depend on. Then naturally one of the species will die off.

Answer:
It would be A: a cell that has double the number of chromosomes as the parent cell 
and if for some reason that is wrong then it could possibly be C and just use the same explanation.
Explanation:
This is because Haploid Gametes are the things that are produced during meiosis-which is a type of cell division which reduces the number of chromosomes in a parent diploid cell by half
 
        
             
        
        
        
During Meiosis, Cell divides "Twice"   (2 times )
Hope this helps!
        
                    
             
        
        
        
The parents should go to gene counciling to determine who carried the gene that was passed down to the offspring.
