The limitation to climate research that could most likely be overcome through scientific design would be that "<span>Data from a wide range of time periods must be analyzed" since we can only gauge what is happening relative to history. </span>
Answer: New vaccines are offered each year because the virus changes.
Explanation: The flue viral strain constantly changes its genetic make up, a process called antigenic drift. As the virus replicates there are small changes that creates new strains which evolve to a completely different influenza virus requiring a new type of vaccine each year.

The genes in a population give forth the genetic variability across a population (genotypes). In addition, occasional mutations of these genes in a population increase this genetic variability. Hovever, natural selection only favours reproduction of individuals with genes that are favourable in the environment/habitat. Therefore, natural selection has no foresight but is rather pegged on being an ‘opportunistic’ process.
Answer:
I believe the answer is A.
Explanation:
Species may share similar physical features because that feature was present in a common ancestor. These features are known as homologous structures.
Answers b, c, and d sound probable, but those responses of foods, habitat, and genetic mutation don't directly correlate with the theory of evolution.
For example: In option d, these organisms all most likely suffered from a genetic mutation, but the similarity of the embryos does not prove that.
