Answer:
D) Yes, it is important that the single-stranded DNA have 3′ ends, so resection must occur in the 5′ to 3′ direction.
Explanation:
During homologous recombination, the exonucleases remove nucleotides from the free 5' ends of the DNA at the double-stranded breaks to create a double-strand gap.
Removal of more nucleotides from the free 5' ends creates 3' single-strand extension which in turn invades the intact homolog and pairs with its complementary sequence of the DNA. The invaded free 3' end is then extended by DNA polymerase to give rise to Holiday junctions.
If the resection occurs in the opposite direction and creates overhangs with free 5' ends, the free 3' ends would not be available to serve as a primer to facilitate the replication.
I am not sure on this but I think it would be B) sorry if this is not the correct answer

Answer:
The correct answer is - "is this factor decreasing the population growth rate in the environment?".
Explanation:
When a factor or resource in the environment causes the decreases or lowers the population growth rate, such factors known as the limiting factors. Limiting factors can be lower food resources, higher competition, lower birth rates, higher death rates, and many other factors.
Thus, the correct question should ask about the limiting factors that are affecting the monarch population would be - "is this factor decreasing the population growth rate in the environment?".
