Who is more likely to acquire dmd, boys or girls? why is that? could a person have a mutated
gene for dystrophin but not have dmd? how?

Boys are more likely to acquire DMD, this is because the dystrophin gene is commonly in the X chromosome. A person can have a mutated gene for dystrophin but not have DMD because they are known as a carrier, but if they see no symptoms the disease will most likely go to their offspring. This is because it could depend on age and how the original carrier lives.

Hope this helps!

i think the answer is g1

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.
