Answer:
Your answer is cytokinins.
Explanation:
Some flowers bloom in the spring while others bloom in the summer. This is an example of Prezygotic reproductive isolation.
Prezygotic barriers, which prevent cross-species mating or fertilisation, often have a more significant impact on overall reproductive isolation in plants than postzygotic barriers, which select against hybrid progeny. Prezygotic barriers typically evolve through adaptive divergence in response to ecological factors such as pollinators and habitat.
In studies, it is interesting to note that blooming time divergence is highest at the habitat boundary; this pattern suggests reinforcement, where selection against inadequate hybrids has increased prezygotic isolation. These case studies of sympatric and reinforcing speciation demonstrate their viability.

Answer:
To view prokaryotes with the compound microscope, you must use an oil-immersion lens (100x objective).
Answer:
The best wavelengths of visible light for photosynthesis fall within the blue range (425–450 nm) and red range (600–700 nm). Therefore, the best light sources for photosynthesis should ideally emit light in the blue and red ranges.

They observed in the offspring bacteria that there was the presence of marked DNA after crossing.
<h3>What is DNA?</h3>
This is referred to as deoxyribonucleic acid and contains the genetic instruction in organisms.
Hershey and Chase experiment involved using bacteriophages to infect a bacteria in which the DNA entered with little or no protein. The presence of marked DNA in the bacteria means it is the biomolecule involved in reproduction.
