Answer:
They evolved from entirely different ancestors, but both developed wings in response to similar ecological conditions.
Explanation:
Based on the info given, they possibly could have had the same ancestor, but even if that was true, the bat would have some type of resemblance other than wings. I think that due to environmental changes, natural selection allowed these organisms to fly so they can survive in that environment. Birds got feathers because they could have been in a cold ecosystem so they needed warmth for themselves and their young as well as stay away from predators, due to their small size they had no way to get away without wings. They didn't have legs for running so they developed wings. Bats may have been in a fine temperature, but the day caused problems due to hunting, so they developed wings to hunt at night and keep themselves in caves to hide from predators.
This is the best I could do, I hope this helped :)

Answer:
(c) Inherited a mutation in a gene required for mismatch repair
Explanation:
Gene mutations are occasional changes that occur in genes, that is, the procedure by which a gene undergoes a structural change. Mutations involve the addition, deletion or substitution of one or a few nucleotides of the DNA strand. Mutation provides the emergence of new forms of a gene and, consequently, is responsible for gene variability.
It is common for several members of the same family to have the same genetic mutations, as the gene affected by the mutation may condition a trait that DNA cannot repair. An example of this is the family shown in the question above, where several people were diagnosed with the same type of cancer while still young. What probably happened in this family was that people diagnosed with cancer inherited a mutation in a gene needed to repair incompatibility.
