Before DNA sequence data became available, phylogenies constructed from anatomical and morphological studies of living and fossi
l plants often supported gnetophytes as the sister group to the angiosperms. If this hypothesis were true, and the rest of the phylogeny as depicted in your text stayed the same, which of these statements would be true? Select all that apply a. Angiosperms would be paraphyletic.
b. The phylogeny would support a single origin for vessels.
c. The phylogeny would support independent multiple origins of double fertilization.
d. Seed plants as a whole would be monophyletic.
e. Cycads would be the sister group to all other seed plants.
These areas have anoxic condition means they have very little to zero dissolved oxygen hence cannot support marine/aquatic life. This is as a result of eutrophication caused by algae blooms. This phenomenon is brought about by pollution of these water reservoirs. These algae bloom take up all the oxygen in the water during their mass decomposgion hence leave no dissolved oxygen for the rest of the marine life.
Dark reaction takes place with the presence or absence of sunlight. Light reaction is considered as the light dependent reaction. Light reaction is also called as photo-chemical phase
