Molecular phylogenies show all land plants are a monophyletic group. this suggests

a) there were many different transitions from aquatic to terrestrial habitats
b) wind-pollinated plants arose first
c) land plants have undergone a diversification since they first colonized terrestrial habitats
d) there was a single transition from aquatic to terrestrial habitats

D.  There was a single transition from aquatic to terrestrial habitats

Explanation:

Based on the molecular differences at the level of DNA sequence and inheritance, the molecular phylogenies show that all land plants are a monophyletic group. This is why it suggests a single transition from aquatic to terrestrial habitats occur.

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.
