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.

[ answer ]

foliated

[ explanation ]

foliation forms in a rock when pressure squeezes the rock together. the rock then has a design of many different color little lines. there are three types of foliated rock. the types are slate, schist, and gneiss. each type of foliated rock is different based on grain size and foliation characteristics. the lines appear when the rock has been under pressure.
