Brain injury classified as an injury of the central nervous system.  

Explanation:

CNS is made up of the brain and spinal cord therefore, Central nervous system injury is found in the brain and spinal cord. When some external injury causes damage directly to the central nervous system.  

An example is a coma it occurs when central nervous got a serious injury.

an adaptation is a change or process by which an organism takes to be better suited for its environment. for example; migration is a behavioral adaptation, this is needed because birds are not built to last extremely cold climates. there are different adaptations because there are different species needing to adjust to different things, bears don't migrate; they hibernate.

the answer would be 2, if crossing over doesn’t occur 2 out of 4 of the daughter cells will have that allele.

hope this : )
