You need more context for people to answer the question. We can’t respond with so little. We need to see the sentence so we can answer you problem.
An antibody, because antibodies are produced for a specific virus and are unique to that virus, that protein is the response to influenza.
Answer: option B) Sympatric speciation is best described as a random event that disrupts the allele frequencies in a population
Explanation:
Sympatric speciation is an event/situation whereby organisms of the same species:
- live in the same territory or nearby territories ( i.e do not live in geographical isolation)
- DO NOT interbreed, but select a sexual mate from a much diverse territory to yield new species or offsprings.
This sexual selection then results in generations of offsprings that are genetically different from the rest of the same species due to uneven gene flow or disruption of alleles among the population of same species.
Thus, only option B is true.
I believe it is a solution, sorry if wrong
