If you look at the taxonomic classification there are 7 levels and they are 1. Kingdom; 2. Phylum; 3. Class; 4. Order; 5. Family; 6. Genus and 7. Species.
The taxonomic level phylum includes greatest number of species for a given genus.
Given that a blowfly starts its lifecycle only if there are appropriate conditions met, one of which is suitable temperature, the correct answers as to what can impact the timing of the blowfly lifecycle is the air temperature.
I don't see how humans will impact when this fly is going to be born, so A and C are incorrect. Leaves also doesn't really affect blowflies, which is why D is incorrect as well.
Answer:
When homologous chromosomes form pairs during prophase I of meiosis I, crossing-over can occur. Crossing-over is the exchange of genetic material between homologous chromosomes. It results in new combinations of genes on each chromosome. It is obviously another source of genetic variation in offspring.
