An ecologist studying plants in the desert performed the following experiment. She staked out two identical plots, each of which included numerous small wildflowers. She found the same five wildflower species in roughly equal numbers in both plots. She then enclosed one of the plots with a fence to keep out major herbivores. After two years, four of the wildflower species were no long present in the fenced plot, but one species had increased drastically. The control plot had no change in species diversity.

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.

explanation:

the menstrual cycle – higher tier. negative feedback mechanisms affect the production of hormones in the menstrual cycle. oestrogen also stimulates the release of lh (luteinising hormone) from the pituitary gland, which in turn controls the production of progesterone.

allowed for the prediction of the properties of missing elements.
