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:
Buying products that are built to last
Explanation:
The goal of a circular economy is to keep things going around the "circle" as many times as possible. This means reusing and repairing items before they are recycled. After being recycled and remade, they will be reused and repaired until it is time to be recycled again. The process keeps continuing. :)
Hope this helps!
Answer:
Carley has become operantly conditioned.
Explanation:
Operant conditioning can be described as a method of learning which focuses on the rewards or punishments that will be given in course for an action. As Carley has learned that whenever she wants a rush of natural adrenaline, she needs to swim forty laps in the pool, she considers it to be a reward. Such type of practices behaviour demonstrates operant conditioning.
Answer:C performing a courtship dance
Explanation:
In ocean waves, water particles move in circles and energy moves horizontally. Ocean waves are orbital progressive waves. The water molecules that make up the wave move in circles, or orbits, as the wave progresses. The ocean orbital waves get their start when wind blows on the open ocean, A gentle wind doesn't have much of an effect, but the stronger wind becomes the more it pushes against the water. It transfers energy to the water as it makes peaks and whitecaps in the water's surface.
