The question is incomplete and the whole question is-
Interbreeding two different species of lovebirds produces offspring unable to build a nest after they mature because they lack the innate knowledge needed to carry the nesting materials. The hybrid offspring do not reproduce, and this limits genetic mixing of the two species. This is an example of:
Answer:
The correct answer is- Hybrid infertility
Explanation:
When members of two different species reproduce and produce offspring, then these offsprings are called hybrid. If the hybrid offsprings are not able to produce viable gamete and do not able to reproduce then this is called hybrid infertility. One of the famous examples is mule produce by breeding between donkey and horse.
So here interbreeding of two species of lovebirds produces offspring that do not reproduce and lack innate knowledge needed to build the nest which limits the genetic mixing between the species due to hybrid infertility.
None of the above is the answerr
The most likely explanation for this phenomena is that this is a result of natural selection.
What actually happened?
When the insecticide was introduced, it killed all of the organisms that were vulnerable to it. However, there was a portion of the population that was immune. Since the immune individuals were the only ones that have survived and left offspring, after some generations in the population of this organism there were only their descendants that have the resistance to the insecticide.

Answer:
<em>The correct option is C) The helicase enzyme unwind the DNA molecule into two strands.</em>
Explanation:
DNA replication occurs in a semi-conservative manner. This means that each strand of the DNA can give rise to a new strand. For the process of DNA replication to begin, firstly it is necessary that the DNA unwinds. Topoisomerases are enzymes which are known to remove the super-coiling of the DNA. Helicases can be described as the enzymes which separate the two strands of DNA from the region where replication has to begin. Hence, option C is correct.
